Editorial assessment of the evidence, not a win probability or a calibrated confidence interval.
Quotes older than 48 hours are marked outdated. EV at an old or undated price is a historical calculation, not a current opportunity. Date-only snapshots have no verified capture time.
Rate lines were compiled September 22, 2026. An older listing still showed Bolaños at 135.5 lbs and filed Marshall as a lightweight; the bout stays the announced featherweight booking. UFC bout counts 5 and 7. Per-round tables omitted. No BetOnline price.
Model methodologyWhat this fight is really about — and the measurements that shape it
Three-round featherweight preliminary bout in the 25-foot APEX cage. Gaston "DreamKiller" Bolaños is 9-5, card rank #61, fight-night age 34. The compiled ledger lists him at 145 lbs; the bout is booked at 145. His compiled rate line is 3.91 SLpM, 47% accuracy, 54% striking defence, 3.54 SApM, 0.75 TD/15 and 0.00 Sub/15. Quang Le submitted him on May 3, 2025. Francis "Fire" Marshall is 10-3, card rank #51 at featherweight. His compiled rate line is 3.19 SLpM, 34% accuracy, 55% striking defence, 3.45 SApM, 2.71 TD/15, 47% takedown accuracy, 88% takedown defence and 0.5 Sub/15. He is 27, American Top Team, and his last two results are a decision over Lucas Brennan and a Round-1 rear-naked choke of Erik Silva. No BetOnline price was posted. We take Marshall 60% / Bolaños 40% at conviction 5 / 10.
Marshall is longer and younger. +2" in height, +3" in reach, +3.5" in leg reach, seven years younger on fight night (34 against 27). Both are orthodox. Bolaños has 5 UFC bouts; Marshall has 7. Both clear the green-sample line. The pair is large reliability on bout count, with the caveat that Marshall's page still files him at lightweight.
Venue FactorThe APEX is 25 feet. A wrestler who shoots 2.71 times per 15 minutes wants that room. A Muay Thai fighter at 50% takedown defence does not get a big cage to run in. The fence is close.
Careers, chins, schedules — and the form they bring into the cage
Six career knockouts sit next to a UFC line with zero knockdowns. The finishing version of him is mostly pre-UFC. In the Octagon he decisions people or gets finished. 50% takedown defence is the matchup cell. 0.00 Sub/15 and zero career submission wins.
Five of his wins are rear-naked chokes. 34% striking accuracy is the hole. 2.71 TD/15 at 47% accuracy and 88% takedown defence are why he is favored. Striking defence 55% against Bolaños at 54% — not a striking mismatch. It is a wrestling mismatch.

Critical InsightCareer win charts: Bolaños 6 KO + 0 Sub + 3 Dec = 9; Marshall 1 KO + 5 Sub + 4 Dec = 10. Bolaños's UFC wins are all decisions. Marshall's last two are a decision and a first-round choke.

No archetype base-rate row — editorial 60/40 · The Muay Thai résumé is why this is 60/40 and not 70/30. Marshall misses too many strikes to treat the wrestling as automatic.

Statistical VerdictStriking defence and absorption are a wash. Marshall shoots more than three times as often per fifteen minutes and defends takedowns at 88% against 50%. Bolaños's edge is accuracy and a striking résumé that has not produced a UFC knockdown.
Round-by-round significant-strike figures are unavailable for this comparison. Missing observations are not zero strikes.
Round-by-round control-time figures are unavailable for this comparison. Missing observations are not zero seconds of control.
Critical InsightBolaños wins by seeing the cards. Marshall wins by seeing the cards or taking the neck. Bolaños has already given up the neck once in the UFC.

Advantages, worst cases, gameplans — and the patterns underneath

Muay Thai résumé; absorption is a wash
Entries into the shot in a 25-foot cage
0.5 Sub/15 and five RNCs against 0.0 Sub/15
Bolaños is a striker who has been submitted and stopped in the UFC and who does not shoot. Marshall is a choke specialist with ugly striking accuracy and a takedown rate that fits the small cage.
Marshall's last two fights are the whole case: a decision, then a first-round choke. Bolaños's last two are a decision and, before that, being choked himself.
Stuff the first layer, make Marshall strike at 34% accuracy, and win the kind of decision he has already won three times in the UFC.

In roughly 60 of 100 readings, Francis Marshall uses the APEX fence, lands the shot the rate line says he throws, and either takes the back for a rear-naked choke (26%) or banks a decision (24%) when the choke does not end it. The knockout share is 10% and is not how this career is built.
In the other 40, Gaston Bolaños keeps it standing, lands the cleaner strike at 47% against 34%, and wins a decision (18%) or a knockout (18%) that his UFC knockdown rate has not shown yet. The submission share is 4%.
Marshall 60 / Bolaños 40, conviction 5 out of 10. The choke and the small cage are the favorite's case. The Muay Thai and the missed strikes are the underdog's case.
