Fight overview

The fight in 30 seconds

Neither heavyweight looks for takedowns, so this will be decided on the feet at range. Diniz, the longer and heavier puncher, waits for Boser to step onto a straight right down the middle, the punch Gokhan Saricam dropped him with in April. Boser has to chop the lead leg, angle off the centre line and drag the fight into the third round, where his workrate starts to count.

Paths that change the fight

  • Tanner BoserFifteen minutes. Eight career decision wins, six UFC trips to the final horn and a Round-2 engine averaging 28 significant strikes landed at 58% — if this fight is still upright and competitive in minute eleven, it is his.
  • Jhonata DinizOne straight right down the middle, thrown from four inches further out than Boser is used to, inside the first ten minutes — the punch Gokhan Saricam found six months ago.
What limits this estimate · Analyst conviction: 5/10
  • Boser wins the volume card: 4.82 significant strikes landed per minute against 3.67, and 3.00 absorbed against 3.41, with defence level at 58%.
  • The leg-kick tax — 32% of his UFC strikes to the legs from a 43-inch leg reach, two inches longer than Diniz's, aimed at the base a heavy counter-puncher needs most.

The Frame

What this fight is really about — and the measurements that shape it

The Analyst's Take

Across thirty-eight UFC rounds between them, these two heavyweights have tried exactly one takedown — Boser, once, against Gokhan Saricam, and it missed. Diniz has never shot in the Octagon. That matters because both of Jhonata Diniz's losses began with his back on the canvas, under Marcin Tybura's elbows and Mário Pinto's mount, and Tanner Boser has no route to that position. So this is a kickboxing match, and there Diniz has two inches of height, four inches of reach, roughly twelve pounds, a heavyweight kickboxing title pedigree and seven knockouts in nine wins. He also has the freshest fact on the board: six months ago a debutant dropped Boser with a straight right and finished him, the first knockdown Boser had ever suffered in the Octagon. Boser owns the busier hands, the cleaner defensive record, a two-inch leg-reach edge, eight career decision wins, a real third-round engine, and Rogers Place — the building where his 2019 hometown debut was called off when his opponent failed a drug test.

Length and mass to Diniz, engine and technique to Boser. Diniz is the bigger man on every axis that matters at heavyweight: two inches taller, four inches longer, and about twelve pounds heavier at their last weigh-ins — 244.5 lb for Boser in Winnipeg in April 2026 against 257 lb for Diniz in Rio in October 2025. Boser has spent the back half of his career as one of the division's smaller heavyweights; he made the light-heavyweight limit twice in 2023, against Ion Cutelaba and Aleksa Camur, before returning to heavyweight. His only physical counter is the 43-inch leg reach, two inches longer than Diniz's, and that is not a decorative stat for him: 41.3% of everything he lands in Round 1 goes to the legs, and he once put 21 of 22 leg kicks on Andrei Arlovski in a single third round. Diniz, by contrast, is a head-hunter whose targeting climbs from 70.2% head in Round 1 to 84.0% in Round 3 — a man looking for one shot, not an accumulation.

Venue Factor
Rogers Place owes Tanner Boser a night. His hometown UFC debut was booked here for UFC 240 on July 27, 2019 against Giacomo Lemos, and it was called off when Lemos tested positive for a banned substance. Boser debuted three months later in Boston instead. Seven years and eleven Octagon appearances later, at 35 and coming off the first standing knockdown of his UFC career, he finally gets the walk he was promised. That is worth real early adrenaline, and adrenaline is exactly what a man with four extra inches of reach and one-shot power wants his opponent to be running on.

The veteran on the way down, and the arc is legible. A 2019–2022 run produced three UFC finishes — Philipe Lins, Raphael Pessoa and Ovince Saint Preux — alongside four decision losses to Ciryl Gane, Andrei Arlovski, Ilir Latifi and Rodrigo Nascimento, the last two on split cards. Then came a 2023 detour to light heavyweight, free agency when his contract ran out after the Aleksa Camur win, a Global Fight League signing that never produced a fight, and a 22-month gap broken by a third-round stoppage of Vinicius Moreira at UAE Warriors 60 in June 2025. The UFC return ended with Gokhan Saricam dropping him with a straight right and finishing him with ground punches at 4:43 of Round 2 — the first time in eleven Octagon appearances anyone had put him down. For most of his career, beating Tanner Boser meant out-pointing him: eight of his eleven losses are decisions, none are submissions, and he went eight years without being stopped after a six-second loss to Tim Hague in 2015. Since 2023 it has twice meant finishing him.

A narrower and stranger arc: five first-round finishes on the Brazilian circuit across Spartacus, Metanoia and Imortal FC, a first-round TKO on Dana White's Contender Series in September 2023 to earn the contract, and a Round-2 knockout of Austen Lane in his Octagon debut — a Performance of the Night after Lane had held him down for most of the first round. Since then: a decision over Karl Williams, a doctor's stoppage against Marcin Tybura, a decision over short-notice newcomer Alvin Hines, and a mount stoppage against Mário Pinto. Behind the record sits a genuine kickboxing pedigree — 22-7 with 15 knockouts, ACB Kickboxing heavyweight champion in 2016, 2021 Tatneft Cup +80 kg winner, and a GLORY veteran who shared a ring with Rico Verhoeven. He has never solved a wrestler and has rarely needed to solve a striker. He withdrew from a June 2026 booking and arrives on a twelve-month layoff, 257 lb on a 6'4" frame at 35.

Pattern

2-3, and two of the three losses are stoppages — a genuine break from a career built on losing decisions. The Camur win is his best modern tape: 120 significant strikes landed across three rounds at 56% accuracy, 5:27 of control time, 30-27 on all three cards. The Cutelaba loss is a wrestling loss dressed as a knockout — one takedown, then 30 of 40 landed including 16-for-16 on the ground, done in 125 seconds. The Saricam loss is the alarming one: Saricam went 0-for-4 on takedowns and the striking was close to level — 60 significant strikes landed by Boser, 57 by Saricam — until a straight right down the middle put him down late in Round 2. Boser is 1-3 in his last four UFC fights and has been stopped twice in that stretch after going eight years without being stopped.

Pattern

3-2, and the split runs along one axis — when he was allowed to stand, he won; when a heavyweight got him down and kept him there, he lost. Against Hines he landed 32-of-55, 37-of-60 and 43-of-67 while stuffing nine of ten takedown attempts; against Williams he landed 36-of-60 in the second round. Even the Lane win began on his back, with 4:10 of first-round control conceded, before he knocked Lane out standing in the second. Against Tybura he was held for 7:14 across two rounds and opened up with elbows until the doctor waved it off. Against Pinto he was taken down twice in Round 1, controlled for 7:28, survived two submission attempts, and was pounded out from mount. In those two losses his combined offensive output was sixteen significant strikes in four rounds. This is a position problem, not a striking problem — and it has shown up in the third round too: Williams took him down twice in the last round of their fight.

Critical Insight
Both the donuts and the round bars cover full professional records — Boser's 12 knockouts, 8 decisions and 2 submissions across 22 wins, Diniz's 7 knockouts and 2 decisions across 9. Boser's finishes are spread across the fight, with six of his fourteen arriving in Round 2 and four more in Round 3 or later, including a fourth-round leg-kick stoppage in a title defence. Diniz's are stacked at the front: six first-round stoppages — five on the Brazilian circuit and one on the Contender Series — while his only UFC finish took until 2:12 of Round 2. Diniz's power is the most dangerous object in the fight; Boser's engine is the most reliable one. And neither of Diniz's UFC decisions was comfortable at the finish: Alvin Hines took him to 29-28 on all three cards, and Karl Williams won the last round with two takedowns.

  • Gokhan Saricam (style proxy): A UFC debutant went 0-for-4 on takedowns, stayed level with Boser in the striking, and won anyway with a straight right down the middle late in Round 2. Diniz fights at range behind a four-inch reach edge, which is where that punch lives.
  • Marcin Tybura & Mário Pinto (style proxy): Both Diniz defeats started with his back hitting the canvas — Tybura's elbows after 7:14 of control, Pinto's mount after 7:28. Boser has tried one takedown in twenty-six UFC rounds and missed it, so the only proven way to beat Diniz is not in his toolkit.

Boser's number is built on volume and defence: more significant strikes landed per minute than the heavyweight average, fewer absorbed, and a defensive rate well above the division norm. Diniz's line is cleaner than it is busy — higher accuracy, level defence, lower output — and his gauge carries an explicit leverage adjustment for four inches of reach, seven knockouts in nine wins and a kickboxing title résumé, none of which a rate formula can see.

Neither man offers any wrestling: one missed takedown attempt between them in thirty-eight UFC rounds and no submission attempts at all. Their takedown defence is near-identical at 70% and 69%, so they are separated on what happens underneath. Boser has never been submitted in 34 professional fights and survived long stretches under Ilir Latifi and Rodrigo Nascimento; Diniz has spent 38.9% of his UFC cage time under control, and both of his losses ended there.

Statistical Verdict
Every volume and absorption marker belongs to Boser, and the defensive rates are level. Accuracy, reach, mass and finishing résumé belong to Diniz. The grappling column is a mutual zero, which removes the mechanism that beat Diniz twice — he has spent nearly two-fifths of his UFC cage time underneath somebody, and Boser has tried one takedown in eleven UFC fights. The honest one-sentence read: Boser wins the fight that is still a fight in minute twelve; Diniz wins the fight that ends with one clean right hand from four inches further away than Boser is used to. With the Saricam knockdown six months old, we give the shorter fight the higher probability — but only just.

Significant Strikes Landed per Round

Control Time per Round (sec)

Tanner Boser

  • Round 2 is his busiest round — 28.0 significant strikes landed at 58% accuracy — and two of his three UFC finishes, Raphael Pessoa and Ovince Saint Preux, came in it.
  • Opponents' accuracy against him barely moves, 41.8% in Round 1 and 41.9% in Round 2, before rising to 44.1% in Round 3, the round in which he also concedes the most control.
  • His targeting is a leg-kick story: 41% of Round-1 output goes to the legs, dropping to 24% in Round 2 and climbing back to 36% in Round 3.
  • One takedown attempt in twenty-six UFC rounds, and 15.5% of his UFC cage time spent under someone else's control.

Jhonata Diniz

  • His accuracy climbs every round — 54.8%, then 59.2%, then 63.3% — though the third-round figure comes from only two fights.
  • So does what he absorbs: 11.2, then 17.2, then 25.0 significant strikes taken per round, and he lost the third round on five of the six judges' cards in his two UFC decisions.
  • Round 1 is where he gets taken down: an average of 2:26 of first-round control conceded, and 11% of his opening-round strikes landed from the ground.
  • Round 2 holds his only UFC knockdown (Austen Lane, April 2024); his head targeting rises from 70% in Round 1 to 84% by Round 3, and body work is almost absent.
Critical Insight
Boser's busiest round and Diniz's most dangerous round are the same one. Boser lands 28 significant strikes per second round; Diniz's only UFC knockdown, his only UFC finish and both of his UFC losses all arrived in a second round, and Saricam's knockdown of Boser came late in the second as well. After that the curves cross: Diniz absorbs more every round and dropped the third on the cards in both of his UFC decisions, while Boser's third-round output runs 132% of his first in the same fights. Diniz's win equity is front-and-middle-loaded; Boser's is middle-and-back-loaded.

The Story of the Fight

Advantages, worst cases, gameplans — and the patterns underneath

Where the fight lives

Who owns each phase — and by how much
Open SpaceJhonata owns it

+4" reach and +2" height with both men at range — 86% of Boser's landed strikes and 94% of Diniz's come at distance — so the jab exchange is his before anyone moves

Pocket / ExchangesJhonata owns it

Boser out-throws him 48 to 34 in the second round, but the only knockdown Boser has suffered in the Octagon came from a straight right at mid-range

ClinchTanner owns it

Boser's clinch share is 9% of his UFC output and nearly doubles in Round 2, against Diniz's 3% — the one place four inches stop mattering

GroundEven

One takedown attempt in 38 UFC rounds between them; Diniz's 38.9% control conceded is the biggest weakness in the fight and Boser owns no tool that reaches it

Path to Victory

Tanner Boser

Fifteen minutes. Eight career decision wins, six UFC trips to the final horn and a Round-2 engine averaging 28 significant strikes landed at 58% — if this fight is still upright and competitive in minute eleven, it is his.

Why they win
01
Volume and workrate

4.82 significant strikes landed per minute against 3.67, and a Round-2 average of 28.0 landed at 58% accuracy against a patient, low-output striker.

02
The leg-kick tax

32% of his UFC strikes go to the legs, 41% in Round 1, from a 43-inch leg reach two inches longer than Diniz's. Against a head-hunter who puts only a fifth of his own output on the legs, this is the highest-leverage tool in the fight for shortening a reach advantage.

03
Defensive rates

3.00 significant strikes absorbed per minute against Diniz's 3.41, with striking defence level at 58% — both men well clear of the heavyweight norm, Boser across more than twice the UFC cage time.

04
Duration and decision identity

Eight career decision wins, six UFC bouts to the horn, and third-round output of 132% of his first in the same fights. Diniz has fought two UFC third rounds and lost both on the majority of the judges' cards.

05
Level of competition

Gane, Arlovski, Latifi, Saint Preux, Nascimento, Cutelaba. Diniz's best UFC win is Karl Williams on the cards. Nothing on the Brazilian's ledger has the timing Boser has already survived fifteen minutes against.

06
Rogers Place

Bonnyville-born, Edmonton-based, and finally fighting in the building where his 2019 debut was called off. The crowd is a real early-round variable for a fighter who lives on activity scoring.

The gameplan
  1. 1
    Open on the legs, not the head

    His Round-1 profile already says so — 41% of his opening-round output goes low. Buy the first round with kicks that do not require entering Diniz's straight-right lane.

  2. 2
    Circle off the centre line and never square up

    Diniz lands 94% of his strikes at distance and three-quarters of them to the head. The straight line down the middle is where his power lives, so the angle is the whole defence.

  3. 3
    Turn it into a Round 2 fight

    His engine is a 28.0-landed round at 58% accuracy. Get there intact and the volume arithmetic starts to pay.

  4. 4
    Attack the body

    Heavy men pay for body work late. Boser's body share runs 18–21% by round, and Diniz, who puts only 5% of his own output there, is not used to living in that exchange.

  5. 5
    Bank rounds, do not hunt the highlight

    Eight decision wins and one knockdown every sixty minutes in the Octagon. A cautious 30-27 is a far better use of this skill set than a swing for a one-punch finish.

  6. 6
    Contingency — if the kicks are being checked

    If he is losing the range battle he must force the clinch and dirty box. His clinch share nearly doubles in Round 2, from 6% to 11%, and it is the only place Diniz's four inches stop mattering. Half-measures at mid-range are exactly how the Saricam fight ended.

Path to Victory

Jhonata Diniz

One straight right down the middle, thrown from four inches further out than Boser is used to, inside the first ten minutes — the punch Gokhan Saricam found six months ago.

Why they win
01
Four inches of reach and two of height

At heavyweight, with both men fighting at distance — 86% of Boser's landed strikes and 94% of Diniz's come at range — the jab exchange belongs to Diniz before either man moves.

02
One-shot leverage

Seven of nine wins by knockout, six of them in the first round, plus an ACB heavyweight kickboxing title, a 2021 Tatneft Cup crown and 15 knockouts in 22 kickboxing wins. The UFC knockdown rates are level — one for Diniz in twelve rounds, two for Boser in twenty-six — so the edge is résumé and leverage rather than Octagon evidence.

03
The Saricam blueprint is six months old

A straight right down the middle put Boser down for the first time in his UFC career, on April 18, 2026. Diniz fights at distance behind a four-inch reach edge, which is exactly where that punch lives.

04
Accuracy that climbs

54.8% in Round 1, 59.2% in Round 2, 63.3% in Round 3, and 59% across his UFC career against Boser's 54%. He gets sharper, not sloppier, as the read develops.

05
Mass

About twelve pounds heavier at their last weigh-ins, 257 lb to 244.5 lb, against a man who made the light-heavyweight limit twice in 2023 and has fought as a smaller heavyweight for most of his career.

06
He is not vulnerable to anything Boser owns

No takedown to fear, no submission to fear, and he has never been knocked down in the Octagon. Both of his stoppage losses required a wrestler, and Boser has tried one takedown in twenty-six UFC rounds.

The gameplan
  1. 1
    Fight behind the jab and take the range for free

    With four extra inches he does not need to be busy — he needs to be first. His modest output is a design choice, not a fitness problem.

  2. 2
    Bait the entry, land the straight right

    Boser must close distance to land. Every step in is a chance at the shot that ended Boser's night in Winnipeg.

  3. 3
    Check and answer the leg kicks

    The one thing that could unmake his frame. Punish each low kick with a right hand over the top rather than absorbing them for free.

  4. 4
    Do not chase Round 3

    His finishes live in the first ten minutes. He lost the third round on five of six judges' cards across his two UFC decisions, and what he absorbs climbs from 11.2 significant strikes in Round 1 to 25.0 in Round 3.

  5. 5
    Stay off the fence and off the ground

    Both losses he owns started with his back going somewhere it should not have. Even against a man with one takedown attempt in eleven UFC fights, a scramble is the only way this goes wrong for him.

  6. 6
    Contingency — if the legs are compromised by Round 2

    He must stop retreating in straight lines and commit to a single overhand sequence per exchange. A patient sniper with a dead lead leg loses a decision he cannot afford at 3-2 in the Octagon.

Danger Zone

How Tanner Boser loses

  • Saricam 2.0 in front of his home crowd — he walks onto a straight right inside the first six minutes, goes down, and is finished on the ground before Rogers Place has finished its first roar.

  • Reach starvation: he spends three rounds a half-step outside his own range and inside Diniz's, never gets the leg kicks going, and drops a 29-28 decision to a cleaner, longer striker.

  • Adrenaline dump — he burns the first ninety seconds on hometown energy, throws a haymaker instead of a leg kick, and hands a counter-puncher the exact geometry he wants.

Danger Zone

How Jhonata Diniz loses

  • The legs go by minute eight. Boser stacks calf and thigh kicks from a 43-inch leg reach, Diniz's base erodes, and the sniper cannot plant to fire.

  • Volume drowning: Boser throws his usual 45-plus significant strikes a round from the second onward, Diniz's absorption curve of 11.2 → 17.2 → 25.0 plays out exactly as it has before, and he loses two rounds without ever being hurt.

  • Cut and stopped again. He has already been waved off once on a doctor's stoppage, Boser has two elbow finishes on his record, and Diniz has never proved he can close a cut and keep working.

Both men arrive with a loaded gun the other cannot fire

The Empty Grappling Column

Across thirty-eight UFC rounds between these two there is one takedown attempt — Boser's, against Saricam, and it missed. Diniz has never shot in the Octagon. That is a shared stylistic identity, not a fluke, and the consequence is specific: Marcin Tybura and Mário Pinto beat Diniz by putting him on his back, and Ion Cutelaba finished Boser the same way — none of them are in this cage. Diniz has spent 38.9% of his UFC cage time under control and has been finished from the bottom twice, the single largest exploitable weakness in the fight, and it sits entirely outside Tanner Boser's toolkit. Symmetrically, Boser's worst tape — 30-of-40 with 16-for-16 on the ground in 125 seconds against Cutelaba — is out of Diniz's reach.

0
takedowns landed across 38 UFC rounds (one attempt)
The most load-bearing fact in the fight

The Saricam Shadow

On April 18, 2026 in Winnipeg, UFC debutant Gokhan Saricam did something ten previous Octagon opponents had not: he knocked Tanner Boser down, with a straight right, and finished him with ground punches at 4:43 of Round 2. Before that night Boser had absorbed no knockdowns in ten UFC fights — he went the distance with Ciryl Gane, Andrei Arlovski and Ilir Latifi without touching the canvas from a strike. The detail that matters most: Saricam went 0-for-4 on takedowns and the striking was close to level, 60 significant strikes landed for Boser to 57 for Saricam. That was not a wrestling loss dressed as a knockout. It was one clean punch down the middle, six months ago — and it is why the fighter with the better rate sheet is the underdog here.

4:43
Round 2, Apr 18 2026 — Boser's first knockdown in eleven Octagon fights
Résumé versus record

Regional Power, Octagon Evidence

Diniz's finishing reputation is real — seven knockouts in nine MMA wins and 15 in 22 kickboxing wins — but six of the seven MMA knockouts came outside the UFC, five on the Brazilian circuit and one on the Contender Series. Inside the Octagon he has one knockdown in twelve rounds, 0.27 per fifteen minutes, essentially identical to Boser's 0.25. The model does not treat him as a proven UFC finisher; his knockout equity rests on the reach gap, the résumé and Boser's April knockdown. This is the strongest single argument for keeping the line at 57 rather than pushing it to 62.

knockdown in 12 UFC rounds for Diniz
Why the underdog is not lower than 43%

Strength of Schedule, Qualitatively

Boser has shared the cage with a future interim heavyweight champion in Ciryl Gane, a former heavyweight champion in Andrei Arlovski, a durable gatekeeper in Ilir Latifi, a long-tenured light-heavyweight contender in Ovince Saint Preux, a current heavyweight in Rodrigo Nascimento and a light-heavyweight veteran in Ion Cutelaba. He lost most of those fights, but he completed fifteen minutes in four of them. Diniz's five-fight UFC résumé tops out at Marcin Tybura, who beat him, and Karl Williams, whom he beat on the cards. Nothing on Diniz's ledger has yet asked him a question Boser has not already been asked several times.

Same age, incomparable mileage

Two Thirty-Five-Year-Olds, Two Different Clocks

Both men are 35 on fight night and neither is young for a heavyweight, but the mileage is not comparable. Boser has 34 professional fights, twenty-six UFC rounds and two stoppage losses in three years. Diniz has 11 professional MMA fights and twelve UFC rounds — offset by a long kickboxing career, a twelve-month layoff and two UFC third rounds that both went to his opponent on the cards. Boser's clock is running out of durability; Diniz's has never been tested deep into a fight. In a three-round bout, the second problem is the smaller one.

The Five-Round Clock

Tanner Boser danger windowJhonata Diniz danger windowNeutral / contested
R1 · 0:00–5:00Maximum danger, minimum output

A genuine paradox. Diniz's Round-1 average is only 11.4 significant strikes landed at 54.8%, and it is the round in which opponents have taken him down, but six of his seven career knockouts came in a first round — none of them in the UFC. Boser should be ahead on activity after five minutes and simultaneously at his highest per-second risk. Estimated finish equity: ~19%.

Critical Insight
Diniz's win equity is front-and-middle-loaded — roughly 28 of his 37 knockout points sit in Rounds 1 and 2. Boser's is middle-and-back-loaded: about 17 of his 21 knockout points sit in Rounds 2 and 3, plus all 21 of his decision points. Boser is favoured to win minutes 6 through 15; Diniz is favoured to make sure minutes 6 through 15 never get scored.

The Verdict

One hundred simulated fights, the betting market, and our conviction

If you only read 3 things
1

Neither heavyweight wrestles — one missed takedown between them in thirty-eight UFC rounds — so the position that beat Diniz twice is off the table and this becomes a kickboxing match at range.

2

Diniz brings four inches of reach, seven knockouts in nine wins and a kickboxing title résumé; Boser brings the busier hands, the lower absorption, eight decision wins, a home crowd, and an opponent who lost the third round in both of his UFC decisions.

3

Model: Jhonata Diniz 57% / Tanner Boser 43%, conviction 5/10 — our technical gauges have them level, so the lean rests on power, reach and the April knockdown rather than the rate sheet.

The Saricam template

The single highest driver in the model. A straight right down the middle on a Boser who has now been dropped once in the Octagon, at 34, by a debutant. It is what makes Diniz's 37 knockout points the largest bucket in the simulation.

Reach and mass at distance

+4 inches of reach, +2 inches of height and roughly +12 lb to Diniz, with both men fighting at range — 86% of Boser's landed strikes and 94% of Diniz's come at distance. There is no phase of this fight where the length gap gets hidden, because neither man goes looking for one.

Boser's Round-2 engine against a low-output opponent

28.0 significant strikes landed at 58% in his peak round, against a fighter who throws 34 per second round and lands 3.67 per minute across his UFC career. It is why Boser's combined decision-plus-TKO equity is 42 points rather than 30.

The absorption curve versus the leg-kick tax

Diniz takes 11.2, then 17.2, then 25.0 significant strikes per round as fights lengthen, and puts only a fifth of his own output on the legs. Boser puts 32% there from a 43-inch leg reach. That collision is the whole of the underdog's late-fight case.

Decision reliability, and the mutual grappling vacuum

Eight career decision wins and six UFC third rounds against two and two — and Diniz lost the third round on five of six cards in his two decisions. One missed takedown across 38 rounds removes the position that beat Diniz twice. Whoever cannot be finished wins on the cards, and that leans toward the older man.

The Saricam Sequel

Boser steps into the lane, and from four inches further out than Gokhan Saricam needed, the straight right lands. Most likely in Round 1 or Round 2, most likely finished on the ground afterwards — the single largest bucket in the simulation and the one that carries the pick.

Tanner Boser win probability
0%
21%

KO/TKODECSUB

  • Higher than his knockdown rate suggests, because Diniz's stoppage history is position-and-accumulation rather than chin failure: a doctor's stoppage from ground elbows and a mount-position pounding. Boser's volume, body work and elbows are a real route to a Round-3 accumulation TKO against a man absorbing 25 strikes per round by then.

  • His primary path. Eight career decision wins, six UFC third rounds, and third-round output of 132% of his first in the same fights. If this fight reaches minute eleven upright and competitive, Boser is the favourite from there.

  • One point, and not a rounding choice. He has no UFC submission attempts and his two career submission wins came in 2013 and 2014 on the Alberta circuit. This covers a choke off a rare scramble and nothing more.

Jhonata Diniz win probability

KO/TKODECSUB

  • The largest single bucket in the simulation and the one that carries the pick. Built on the four-inch reach gap, seven knockouts in nine wins, a kickboxing title pedigree, and the fact that Boser was dropped by a straight right and finished six months ago — the first knockdown of his UFC career.

  • Deliberately modest. He is a patient, low-output striker who lost the third round on five of six cards in his two UFC decisions, is coming off a twelve-month layoff, and faces a man who throws roughly twelve more significant strikes per round.

  • Zero. He has no career submission wins, no UFC submission attempts, and no UFC takedown from which to hunt one. There is no submission branch on his side of this fight.

Original analyst price notes

These notes describe the original analysis and may refer to older prices.

Every figure here is an MMA Analytics model percentage, not a book's price. The cleanest structural read on the board is that the fight does not go the distance — our model puts that at 59% against 41% for the full fifteen minutes, on two heavyweights with no takedown offence, a combined nineteen knockout wins, and both coming off second-round stoppages in their most recent outings. By round, the model splits it roughly 19% in Round 1, 22% in Round 2 (the highest single-round finish cluster) and 18% in Round 3. Second-best, once the market opens: Boser by decision at plus money. Our 21% on that bucket is built on eight career decision wins, six UFC third rounds and a 132% third-round output ratio, against an opponent who lost the third round in both of his UFC decisions. The bet we would actively avoid is anything by submission — the model prices either fighter by submission at roughly 1%, on zero career submission wins for Diniz, zero UFC submission attempts for either man, and one missed takedown between them in thirty-eight UFC rounds.

Conviction
0
5/10

Editorial confidence in the evidence, not a win probability or a calibrated confidence interval.

A real but honest lean. The rate sheet favours Boser and our technical gauges have them level; we are picking Diniz on reach, knockout résumé and one six-month-old knockdown, and saying so out loud. Two thirty-five-year-olds coming off stoppage losses, one with the busier hands and the home cage, one with the bigger frame and the bigger punch, in a division where a single clean shot outweighs fourteen minutes of arithmetic. That is a five, not a seven. Lean: Jhonata Diniz.

What backs the lean

  • +4" reach, +2" height and roughly +12 lb at heavyweight, with both men committed to fighting at distance.

  • Seven knockouts in nine wins, plus an ACB heavyweight kickboxing championship, a 2021 Tatneft Cup crown and 15 knockouts in 22 kickboxing wins.

  • The Saricam knockdown is six months old — Boser's UFC chin held for ten fights and then broke, at 34, to a straight right down the middle.

  • Boser does not wrestle, which closes the only method that has ever beaten Diniz; the 38.9% control-conceded figure is unexploitable here.

  • Rising accuracy by round — 54.8%, 59.2%, 63.3% — and 59% across his UFC career against Boser's 54%.

  • Never knocked down in five UFC fights, including a first round spent under Austen Lane before he knocked Lane out in the second.

What limits it

  • Boser wins the volume card: 4.82 significant strikes landed per minute against 3.67, and 3.00 absorbed against 3.41, with defence level at 58%.

  • The leg-kick tax — 32% of his UFC strikes to the legs from a 43-inch leg reach, two inches longer than Diniz's, aimed at the base a heavy counter-puncher needs most.

  • Eight career decision wins, six UFC third rounds and third-round output of 132% of his first, against a Diniz who lost the third on five of six cards in his two UFC decisions.

  • Level of competition: Gane, Arlovski, Latifi, Saint Preux. Diniz's best win is Karl Williams on the cards.

  • Diniz's absorption rises to 25.0 significant strikes per round in Round 3.

  • A twelve-month layoff for Diniz, including a withdrawal from a June booking, against six months for Boser — and Rogers Place, the building whose 2019 card lost Boser's hometown debut.

  • Our technical gauge has them level, 41 to 40.5. We are leaning on power and reach; readers who weight the rate sheet over leverage should treat this as close to a coin flip.

Final Assessment

In roughly 57 of 100 simulations, Jhonata Diniz's four extra inches and one clean right hand decide the night — most often as a Round-1 or Round-2 knockout as Boser steps into the lane Gokhan Saricam found six months ago (37%), and otherwise as a narrow decision built on cleaner work at a range Boser cannot comfortably reach (20%). There is no submission branch: Diniz has never recorded one, never attempted one in the Octagon, and has never attempted a UFC takedown from which to hunt one.

In the other 43, Tanner "The Bulldozer" Boser buys the fifteen minutes he has spent a decade learning how to buy — banking rounds behind a 43-inch leg reach and a Round-2 engine that averages 28 significant strikes landed at 58% accuracy, and taking a decision the Edmonton crowd will hear coming from the second round (21%). In another 21, that accumulation becomes a stoppage: Diniz's absorption climbs to 25 strikes per round by Round 3, his lead leg is gone, he has already been waved off once on a doctor's stoppage, and Boser's volume, body work and elbows finish a heavyweight who has faded in both of his UFC third rounds. The final 1 is a scramble nobody can script.

The data gives Diniz the reach, the mass, the accuracy, the knockout résumé and the freshest exploitable evidence in the fight; it gives Boser the volume, the absorption edge, the engine, the level of competition and the building. Because neither man wrestles, the position that beat Diniz twice is off the table — which turns this into fifteen minutes of pure kickboxing between a sniper and an accumulator. On October 17 in Edmonton, we take the sniper, narrowly and without comfort — and we will not fade the Bulldozer's decision at plus money in the one arena that already owes him a night.
