Fight overview

The fight in 30 seconds

Blaydes's wrestling and longer historical control time give him a route to take away Cortes-Acosta's boxing exchanges. Watch the first scramble after each entry: quick returns to the feet would make Blaydes spend energy without securing the attacking positions he needs.

Paths that change the fight

Waldo Cortes-AcostaStuff the chain, not the shot. If he is still standing at distance in the second round — where his output rises to 31.2 significant strikes and Blaydes's takedown rate falls to its lowest — he wins a kickboxing match against a man whose every loss is a knockout.
Curtis BlaydesThree entries, one per round. He does not need a finish; 107 seconds of first-round control and 169 in the third is a 29-28 card before anything else happens.

What limits this estimate · Analyst conviction: 4/10

All five of his statistical record defeats are knockouts, into an opponent who drops 0.78 opponents per fifteen minutes.
Cortes-Acosta lands 5.34 significant strikes per minute to Blaydes's 4.18 and has never been finished or dropped.

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

The Analyst's Take

A heavyweight identity clash with almost no overlap. Waldo Cortes-Acosta lands 5.34 significant strikes per minute — 7th of 36 active heavyweights — and 85% of his career output lands standing at distance; he has never been finished, and all his defeats have come on the cards. Curtis Blaydes attempts 5.12 takedowns per fifteen minutes, 4th in the division against a 1.60 average, and banks 107, 87 and 169 seconds of control across the three rounds of a normal fight. Every one of Blaydes's five statistical record losses is a knockout. The fight is one question asked three times: does the shot land, or does the punch?

Fighting Style

Chain wrestling into top control

Frames are all but identical — both men measure 76 inches tall, and the reach gap is two inches, not the eight the stale statistical record stub used to suggest. Age is a wash inside eighteen months, and it runs the other way from the editorial assessment: Cortes-Acosta is 34 on fight night, Blaydes 35. What separates them is Octagon mileage. Blaydes debuted in April 2016 and has twenty UFC bouts and five knockout defeats behind him; Cortes-Acosta debuted in October 2022 and has twelve, none of them ending early. Neither man has a published leg reach, which matters here because 28.7% of Blaydes's opening-round strikes land on the legs.

Venue Factor
A full-size 30ft Octagon is the neutral surface, and neutral favours the kickboxer marginally: extra space punishes a failed level change and lengthens the walk back to the fence. But Blaydes has spent a decade closing exactly that distance — 64 takedown attempts in first rounds alone across twenty Octagon fights, 35 of them landing. Three rounds also compresses the fight into the shape he prefers: he does not need a finish, he needs entries, and 363 seconds of average control across three rounds is a scorecard whether or not anything else happens.

Four years from debut to the top five. He arrived in October 2022 as a decision-winner — Vanderaa, Sherman, Arlovski, Despaigne, Spivac all went the distance — and then turned into a finisher: Ryan Spann in the second, Ante Delija in the first, Shamil Gaziev in 1:22, Derrick Lewis in the second at UFC 324. The rate line explains it. He lands 5.34 significant strikes per minute against a divisional average of 4.79, and 85% of his career output lands standing, 4% in the clinch, 10% on the ground. The losses are as informative as the wins: Pavlovich, de Lima and Volkov all beat him on the cards, and none of the three could put him down. Zero knockdowns absorbed across twelve Octagon fights.

Chin · Vulnerable — every statistical record loss is a knockoutSOS · Championship-adjacentChain wrestler into ground-and-pound (statistical record label: MMA)

A decade of the same fight, executed better than almost anyone in the division's history. Blaydes attempts 5.12 takedowns per fifteen minutes — fourth of 36 active heavyweights, more than three times the 1.60 average — and 38% of his career significant strikes land on the ground against 49% standing. It has produced a five-round decision over Alexander Volkov, knockouts of Overeem, Dos Santos, Daukaus and Jailton Almeida, and a title eliminator résumé. It has also produced a single, consistent failure mode: all five of his statistical record defeats are knockouts, to Ngannou twice, Derrick Lewis, Sergei Pavlovich and Tom Aspinall. He has never lost a decision, and he has never been submitted. If he is beaten, he is beaten upright and early.

Pattern

The shape is unusually legible: he stops power heavyweights who stand and trade, and he loses decisions to long, disciplined kickboxers who refuse to trade. Delija, Gaziev and Lewis were finished in the first two rounds. Pavlovich, de Lima and Volkov out-managed the distance for fifteen minutes and won the cards without ever hurting him. Blaydes fits neither template — he is not a puncher standing in the pocket, and he is not a range manager. He is the first opponent in a while whose plan is to remove the fight from the ledger entirely.

Pattern

Five fights, three of them ending inside a round, and none of them by decision except the Kuniev split. Blaydes beat Tom Aspinall in fifteen seconds in 2022 and was knocked out by him in sixty seconds at UFC 304; that pair of results is the whole scouting report. When the wrestling arrives he banks minutes nobody can take back — Almeida, a grappler, was knocked out from top position in 36 seconds. When a heavyweight with timing catches him coming forward, it ends. The Kuniev split decision was a return to the grinding identity after the Aspinall loss, and it was close.

Critical Insight
Both donuts are scoped to Octagon wins only — Cortes-Acosta's ten and Blaydes's fourteen — because the regional portion of Cortes-Acosta's record is not itemised in the statistical record and mixing a twenty-fight UFC tenure against a twelve-fight one on different scopes flatters nobody honestly. the editorial assessment's full-career line for Cortes-Acosta reads 9 KO / 1 submission / 7 decisions. Read at UFC scope the two men are near-inverses in timing rather than method: three of Cortes-Acosta's five stoppages arrive in the first round off a cold start, while six of Blaydes's eight arrive in the second, after a round of control has already softened the opponent. Neither man has a UFC submission win.

Statistical Verdict
Blaydes's takedown line is historically among the best the division has produced and the table says so plainly: 5.12 takedowns per fifteen minutes, fourth of 36 active heavyweights, against a divisional average of 1.60 — more than three times the field. Pair it with 2.76 significant strikes absorbed per minute and you have a fighter who takes limited damage while banking control. The counterweights are equally clear. His own takedown defence is 35%, and his 0.17 knockdown average is 22nd. Cortes-Acosta ranks 7th in output, 10th in knockdown rate and 13th in takedown defence at 73% — above the 71.0% average, but that number has never met an attacker at Blaydes's volume.

Significant Strikes Landed per Round

Control Time per Round (sec)

Waldo Cortes-Acosta

His output nearly doubles after the opening five minutes: 17.2 significant strikes in the first round, 31.2 in the second, 31.1 in the third. He is an accelerator, not a blitzer.
He barely leaves distance — 87.9%, 84.3% and 90.8% of his round-by-round offence lands at range, with clinch shares of 5.8%, 2.5% and 1.8%. There is no phase of his game that wants the fence.
The knockdowns are early: 0.33 per first round and 0.22 per second, then zero in seven third rounds. His targeting migrates upward too — 59.2% head in the first round, 78.0% by the third — while body work falls from 23.3% to 10.1%.

Curtis Blaydes

The wrestling arrives immediately and returns late: 1.75 takedowns landed in an average first round from 3.2 attempts, 0.88 in the second, 1.43 in the third. Control follows the same curve — 107, 87, then 169 seconds.
His striking is a by-product of position. Ground share climbs from 31.5% of first-round offence to 46.1% in the second and 42.0% in the third, while distance share falls from 53.8% to the low forties.
The third round is his most efficient: 19.7 significant strikes at 62% accuracy off 169 seconds of control across seven third rounds. He also has one fourth and one fifth round on record — 3 and 2 takedowns, 219 and 206 seconds of control — which are excluded here because this is a three-round bout.

Critical Insight
The two curves cross in the second round and that is the fight. Cortes-Acosta's output jumps 81% between the first and second rounds, precisely when Blaydes's takedown rate dips to its lowest point of the fight at 0.88 and his control drops to 87 seconds. If Cortes-Acosta is still upright at the ten-minute mark he is fighting in his best round against Blaydes's worst. The problem is the round before it: 1.75 takedowns and 107 seconds of control in an average opening five minutes is a round already banked, and 90.8% of Cortes-Acosta's third-round offence lands at a range he will not reach if his back is on the fence.

Path to Victory

Waldo Cortes-Acosta

Stuff the chain, not the shot. If he is still standing at distance in the second round — where his output rises to 31.2 significant strikes and Blaydes's takedown rate falls to its lowest — he wins a kickboxing match against a man whose every loss is a knockout.

Why they win

Fifty percent more volume

5.34 significant strikes per minute to 4.18, 7th of 36 heavyweights against 20th. In any minute the fight is upright and at range, he is out-landing Blaydes comfortably.

Never been finished

Twelve Octagon fights, zero knockdowns absorbed, and all three career defeats on the scorecards. Pavlovich needed fifteen minutes and a decision; the same man knocked Blaydes out in 3:08.

He beat the man who knocked Blaydes out

Derrick Lewis stopped Blaydes in the second round in 2021. Cortes-Acosta stopped Lewis in the second round at UFC 324.

Takedown defence above the divisional line

73% against a 71.0% average, 13th of 36 — and 0.78 knockdowns per fifteen minutes, 10th, waiting for a failed entry.

The second-round crossover

His output climbs 81% between rounds one and two exactly as Blaydes's takedown rate bottoms out at 0.88 and control falls to 87 seconds.

The gameplan

1
Fight in the middle of the cage
87.9% of his first-round offence lands at distance and 1.8% of his third-round offence lands in the clinch. Every second against the fence is a second his game does not exist.
2
Punish the failed entry
Blaydes lands 35 of 64 first-round attempts, which means 29 of them fail. 0.78 knockdowns per fifteen minutes is what a failed shot should cost.
3
Survive round one, then throw
The whole plan is chronological. His output goes 17.2 to 31.2 between rounds one and two; Blaydes's control goes 107 to 87. Reach the second round upright.
4
Get up immediately, not comfortably
He has 84 seconds of career control across a full three rounds — he has never had to fight from the bottom against anyone like this. Minutes surrendered on the mat are unrecoverable on a three-round card.
5
Work the body early
23.3% of his first-round output goes to the body, his highest share of any round. A heavyweight who wants to shoot three times a round is a heavyweight whose ribs decide the third.

Path to Victory

Curtis Blaydes

Three entries, one per round. He does not need a finish; 107 seconds of first-round control and 169 in the third is a 29-28 card before anything else happens.

Why they win

A top-four takedown engine

5.12 landed per fifteen minutes against a divisional average of 1.60 — fourth of 36, and more than thirteen times Cortes-Acosta's 0.40.

Six minutes of control a fight

107, 87 and 169 seconds across three rounds is 363 seconds — over a fifth of the fight spent in a position his opponent has essentially never had to defend.

He takes limited damage

2.76 significant strikes absorbed per minute against Cortes-Acosta's 3.63. Wrestling is also defence.

Twenty Octagon fights and championship rounds

A five-round decision over Alexander Volkov, an interim title shot, and wins over Overeem, Hunt, Dos Santos and Almeida. Cortes-Acosta has never fought past fifteen minutes.

His third round is his best

19.7 significant strikes at 62% accuracy off 169 seconds of control — the round most opponents fade in is the round he lands most efficiently.

The gameplan

1
Enter in the first ninety seconds
1.75 takedowns and 107 seconds of control in an average opening round, before the 31-strike second round arrives. The earlier the entry, the cheaper it is.
2
Chain, never single
73% takedown defence stops a shot; it does not stop the third attempt of a sequence against the fence. Cortes-Acosta has faced 0.40 takedowns per fifteen minutes of his own, not five.
3
Do not kickbox for free
4.18 SLpM against 5.34 is a losing trade at range, and 0.78 knockdowns per fifteen minutes is exactly the number that ended his nights against Lewis, Pavlovich and Aspinall.
4
Ground-and-pound to hold position
38% of his career strikes land on the ground and Almeida was finished from top in 36 seconds. Damage discourages the scramble and turns control into a judged round.
5
Bank the third
169 seconds of control at 62% accuracy is his best round on record. If the card is level after ten minutes, the closing five are statistically his.

Danger Zone

How Waldo Cortes-Acosta loses

The first shot lands inside ninety seconds and the round becomes 107 seconds of fence and mat. On a three-round card that single event is a third of the scorecard.
He spends the second round standing up instead of throwing, and the 31.2-strike surge that is his entire statistical case never happens.
73% takedown defence is a rate against ordinary attempt volume. Against 3.2 attempts in an opening round alone, one stop in four is a lot of successful entries.

Danger Zone

How Curtis Blaydes loses

A level change is timed and he is caught coming in. Every one of his five statistical record defeats is a knockout, and Cortes-Acosta drops 0.78 opponents per fifteen minutes.
The entries fail early, the fight becomes a kickboxing match, and he is out-landed by 55% for the ten minutes he cannot get it to the floor.
Derrick Lewis knocked him out in the second round and Cortes-Acosta knocked Lewis out in the second round. The transitive tape is not flattering.

The fight's central axis

Five-Point-Three-Eight

Curtis Blaydes lands 5.12 takedowns per fifteen minutes — fourth of 36 active heavyweights, against a divisional average of 1.60. Waldo Cortes-Acosta has defended a career total of 0.40 takedown attempts per fifteen minutes of his own opposition. His 73% defensive rate is real, but it has never been asked the question three times a round.

5.12

Why the dog is live

The Chin Asymmetry

Every one of Blaydes's five statistical record losses is a knockout — Ngannou twice, Lewis, Pavlovich, Aspinall. Cortes-Acosta has never been finished and has absorbed zero knockdowns in twelve Octagon fights; all three of his defeats are decisions. In a division where durability is a skill, one man has it and the other has been beaten only by not having it.

The same opponent, two different answers

Sergei Pavlovich, Twice

Pavlovich beat both men. He needed a full fifteen minutes and a unanimous decision to beat Cortes-Acosta, who was never dropped. He knocked Blaydes out in 3:08 of the first round. It is the cleanest controlled experiment on the card.

Where the curves meet

The Second-Round Crossover

Cortes-Acosta's output rises from 17.2 significant strikes in round one to 31.2 in round two — an 81% jump. Blaydes's takedown rate falls from 1.75 to 0.88 and his control from 107 to 87 seconds over the same interval. Minutes five to ten are the underdog's window, and both fighters' data agree on it.

Ninety Percent at Distance

87.9%, 84.3% and 90.8% of Cortes-Acosta's round-by-round offence lands at range; his clinch share falls to 1.8% by the third round and only 10% of his career strikes land on the ground. He has no fence game and no bottom game on record — which is precisely the ground Blaydes contests.

The Five-Round Clock

Waldo Cortes-Acosta danger windowCurtis Blaydes danger windowNeutral / contested

R1 · 0:00–5:00Blaydes's entry window

1.75 takedowns landed from 3.2 attempts and 107 seconds of control in an average opening round. It is also where Cortes-Acosta drops 0.33 opponents per round, so the round is not free — but it is where the wrestler's model is at its most efficient.

Critical Insight
This fight has a strict chronology and both men know it. Blaydes wants round one and round three — the two rounds where his control peaks at 107 and 169 seconds. Cortes-Acosta wants round two, the only round where his output surge and Blaydes's wrestling trough land in the same five minutes. Whoever imposes their timeline takes two of three rounds, and on a three-round card that is the whole fight.

The Verdict

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

If you only read 3 things

Curtis Blaydes attempts 5.12 takedowns per fifteen minutes — fourth of 36 active heavyweights, against a 1.60 divisional average — and banks 363 seconds of control across a three-round fight. Waldo Cortes-Acosta has 84.

Every one of Blaydes's five statistical record losses is a knockout. Cortes-Acosta has never been finished, has absorbed zero knockdowns in twelve Octagon fights, and stopped the Derrick Lewis who knocked Blaydes out.

Model: Blaydes 58% / Cortes-Acosta 42%, conviction 4/10 — a wrestling-tax lean held down by the underdog's 5.34 strikes a minute and the favourite's documented off-switch.

Each square = 1 simulated fight. Waldo Cortes-Acosta gold · Curtis Blaydes orange · full color = decision, 70% = submission, 45% = KO/TKO.

Entry volume versus stop rate

5.12 takedowns per fifteen minutes against 73% defence. Even at a quarter conversion, three attempts a round produce enough control to decide a three-round card — which is why the Blaydes decision bucket is 40, the largest on the page.

The knockout asymmetry

All five of Blaydes's statistical record losses are knockouts and Cortes-Acosta has never been dropped, let alone finished. That single fact is worth 18 win-shares to the underdog and caps conviction at 4 out of 10.

Round-two timing

Cortes-Acosta's output rises 81% into the second round exactly as Blaydes's takedown rate falls to its low. If the fight is standing at the ten-minute mark, the 22-point decision bucket for the Dominican becomes live.

Damage economics

Blaydes absorbs 2.76 significant strikes per minute. He is not merely a wrestler — he takes less damage than most kickboxers while banking control, which is how a 4.18 SLpM fighter survives volume.

Common-opponent evidence

Cortes-Acosta stopped Derrick Lewis, who knocked Blaydes out. Pavlovich needed a decision to beat Cortes-Acosta and 3:08 to beat Blaydes. The transitive read favours the underdog and the wrestling read favours the favourite; the model splits the difference at 58-42.

Waldo Cortes-Acosta win probability

18%

22%

KO/TKODECSUB

0.78 knockdowns per fifteen minutes, 10th of 36, aimed at a fighter whose every recorded defeat is a knockout. Three of his five Octagon stoppages arrived in the first round and two in the second — the same windows Blaydes has been finished in.

Two points. He has 0.10 submission attempts per fifteen minutes and no Octagon submission win; these are scramble outcomes rather than a hunted path.

16%

40%

KO/TKODECSUB

Eight of his fourteen Octagon wins ended inside the distance, six of them in the second round after a round of control. Against a man who has never been dropped, the finish is a by-product of position rather than a plan.
The single largest bucket on the page at 40. 363 seconds of control across three rounds decides a three-round card without a single moment of danger, and he has six UFC decision wins to prove the shape.
Two points. He records 0.00 submission attempts per fifteen minutes and has never submitted anyone in the Octagon — these are opportunistic chokes off a scramble, not a threat to plan around.

Original analyst price notes

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

Cortes-Acosta by KO/TKO is the live underdog side the analysis flags and the simulation supports: 18 of his 42 win-shares, in a matchup where the favourite has been knocked out five times and the underdog has never been dropped. On the other side, Blaydes by decision is the structural chalk — 40 of 100 outcomes, the largest single bucket on the page. If the market prices Blaydes as a heavy favourite purely on the wrestling narrative, the underdog's inside-the-distance line is where the model disagrees most sharply.

Conviction

4/10

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

A wrestling-tax lean on a fighter who takes 5.12 takedowns per fifteen minutes into a three-round card — held to four out of ten because his opponent has never been finished, out-strikes him by 55%, and every loss on Blaydes's record is a knockout. Lean: Curtis Blaydes.

What backs the lean

5.12 takedowns per fifteen minutes, 4th of 36 heavyweights, against a divisional average of 1.60.
363 seconds of average control across three rounds, to Cortes-Acosta's 84.
2.76 significant strikes absorbed per minute against 3.63.
Twenty Octagon fights including championship rounds and a five-round decision over Alexander Volkov.

What limits it

All five of his statistical record defeats are knockouts, into an opponent who drops 0.78 opponents per fifteen minutes.
Cortes-Acosta lands 5.34 significant strikes per minute to Blaydes's 4.18 and has never been finished or dropped.
The common opponents lean the other way: Cortes-Acosta stopped Derrick Lewis, who knocked Blaydes out; Pavlovich needed fifteen minutes for one and 3:08 for the other.
Blaydes's own takedown defence is 35%, and his knockdown average of 0.17 gives him almost no threat standing.

Final Assessment

The wrestling case is close to unanswerable on paper. Curtis Blaydes lands 5.12 takedowns per fifteen minutes against a heavyweight field that averages 1.60, and his control curve — 107 seconds in the first round, 169 in the third — is the shape of a three-round decision that never needs a single dangerous moment. Waldo Cortes-Acosta has spent his whole Octagon career at distance: 85% of his strikes land standing, 10% on the ground, and he has accumulated 84 seconds of control across an entire twelve-fight run. He has no fence game and no bottom game on record.

The reason this is 58-42 and not 70-30 is the other ledger. Blaydes has been beaten five times in the statistical record and every one of them is a knockout — Ngannou twice, Lewis, Pavlovich, Aspinall. Cortes-Acosta has been beaten three times and every one of them is a decision, with zero knockdowns absorbed across twelve fights. Then there is the cleanest evidence on the page: Derrick Lewis knocked Blaydes out in the second round, and Cortes-Acosta knocked Lewis out in the second round. The transitive tape and the wrestling tape point in opposite directions, which is exactly what a four-out-of-ten conviction looks like.

The honest read: take Blaydes narrowly, on entries rather than damage, and expect a 29-28 card built from a banked first round and a re-taxed third. But the second round belongs to Salsa Boy — 31 significant strikes at the exact moment the wrestling rate dips to its lowest — and if Blaydes is still upright at the ten-minute mark, the fight has quietly become the one he loses.
