Benoit Saint Denis vs. Mauricio Ruffy – Fight Preview and Prediction

By: Kim Smith Updated 09/04/2025, 10:21 AM ET

The Accor Arena in Paris is set to erupt on September 6, 2025, as UFC Fight Night 258 delivers a lightweight co-main event that pits French fan-favorite Benoit Saint Denis against Brazil’s knockout sensation Mauricio Ruffy. This classic striker vs. grappler showdown promises chaos, with Saint Denis’ relentless pressure colliding head-on with Ruffy’s pinpoint, fight-ending striking. Will “God of War” drag Ruffy into deep waters, or will “One Shot” live up to his nickname with a highlight-reel finish? For the sharpest insights and expert analysis on this banger and more, dive into our free UFC picks to stay ahead of the action.

The Striker vs. Grappler Angle

This matchup is a textbook clash of styles. Benoit Saint Denis, a former French special forces soldier, thrives in the grinder, chaining takedowns (4.19 per 15 minutes) and hunting submissions (1.5 attempts per 15 minutes) with a pace that breaks opponents. His southpaw stance and volume striking (5.39 significant strikes per minute) keep foes on their heels, but it’s his wrestling and ground control that define his game. Mauricio Ruffy, by contrast, is a striking savant whose capoeira-inspired movement and devastating power (11 of 12 wins by KO/TKO) make him a nightmare on the feet. His 100% takedown defense in the UFC suggests he can keep fights standing, where his 58% striking accuracy and 4.54 significant strikes per minute shine.

Past fights illustrate the stakes of this dynamic. Look at Dustin Poirier vs. Justin Gaethje (UFC 291, 2023), where Gaethje’s striking overwhelmed Poirier’s grappling attempts with a second-round head-kick KO. Similarly, Khabib Nurmagomedov vs. Conor McGregor (UFC 229, 2018) showed how a grappler’s persistence can smother a striker if takedowns land consistently. Ruffy’s ability to stuff Saint Denis’ shots will dictate whether this becomes a striking clinic or a grappling war.

    • Strikes Landed per Minute: 5.39 (55% accuracy).
    • Striking Defense: 41%, a notable weakness, absorbing 4.61 significant strikes per minute.
    • Takedown Accuracy: 39%, averaging 4.19 takedowns per 15 minutes.
    • Takedown Defense: 70%.
    • Submission Attempts: 1.5 per 15 minutes.
    • Recent Performance: Submitted Kyle Prepolec via arm-triangle choke (UFC 315, May 2025), rebounding from TKO losses to Renato Moicano and Dustin Poirier in 2024.
  • Mauricio Ruffy:
    • Strikes Landed per Minute: 4.54 (58% accuracy).
    • Striking Defense: 61%, absorbing 4.59 significant strikes per minute.
    • Takedown Accuracy: 15% (minimal attempts, no recorded UFC takedowns).

    • Submission Attempts: 0.5 per 15 minutes.
    • Recent Performance: Knocked out King Green with a spinning wheel kick (UFC 313, March 2025), earning a Performance of the Night bonus. Undefeated in UFC (3-0).

X-Factors

  • Conditioning: Saint Denis’ relentless pace is a double-edged sword. His cardio holds up in chaotic fights, but his porous striking defense (41%) leaves him vulnerable to clean strikers like Ruffy, who could exploit early openings. Ruffy’s stamina is less tested, as his fights often end quickly, but he showed some fatigue in a three-round war with James Llontop (UFC 309, November 2024).
  • Experience: Saint Denis has faced higher-caliber opponents (Poirier, Moicano, Frevola), giving him an edge in handling pressure-packed moments. Ruffy’s 3-0 UFC run is impressive, but his opponents (Green, Llontop, Mullarkey) are a step below Saint Denis’ resume.
  • Training Camps: Saint Denis trains with Bulgarian Top Team, a disciplined camp that sharpens his grappling. Ruffy, part of the Fighting Nerds alongside Caio Borralho, benefits from a creative, strike-heavy system that’s produced highlight-reel KOs. No major camp disruptions reported for either fighter.
  • Recent Injuries/Weight Cuts: No confirmed injuries for either, though Saint Denis’ durability took a hit after absorbing heavy damage against Moicano and Poirier. Ruffy’s clean bill of health and minimal damage taken in recent fights give him a slight edge.

Odds Breakdown

  • Moneyline (as of August 2025, per FanDuel and Odds Shark):
    • Ruffy: -225 favorite, reflecting his knockout prowess and undefeated UFC streak.
    • Saint Denis: +187 underdog, with value tied to his grappling and home crowd support.
  • Round Totals: Over 2.5 rounds (+110), Under 2.5 rounds (-140), leaning toward a finish given both fighters’ 100% finish rates in wins.
  • Market Movement: The line opened at Ruffy -210, Saint Denis +175, with slight movement toward Ruffy as public money backs his highlight-reel potential. Sharps, however, see value in Saint Denis’ grappling and Paris crowd boost, keeping the line competitive.

Picks & Fight Prediction For Saint Denis vs. Ruffy

This fight hinges on one question: can Ruffy keep it standing, or will Saint Denis drag him to the mat? Ruffy’s 100% takedown defense is untested against a wrestler of Saint Denis’ caliber, who averages over four takedowns per fight. If Saint Denis lands early shots and chains wrestling attempts, he could sap Ruffy’s energy and hunt for a submission, much like he did against Prepolec. However, Ruffy’s elite striking (58% accuracy) and ability to land fight-altering shots (three UFC knockdowns in three fights) exploit Saint Denis’ shaky striking defense (41%). The Frenchman’s losses to Moicano and Poirier exposed his vulnerability to precise strikers, and Ruffy’s spinning wheel kick KO of Green shows he can end fights in an instant.

The Paris crowd will fuel Saint Denis, but Ruffy’s composure and technical striking give him the edge if he avoids the ground. Expect Saint Denis to push a frenetic pace early, testing Ruffy’s takedown defense. If Ruffy stuffs those attempts and keeps distance, his cleaner striking should rack up damage. Given Saint Denis’ history of eating clean shots and Ruffy’s knockout power, the Brazilian is likely to find a finishing blow in the second or third round.

Fight Prediction: Mauricio Ruffy wins via TKO in Round 2. His striking precision and takedown defense will neutralize Saint Denis’ pressure, leading to a devastating counter that ends the fight.

Best Bets:

  1. Ruffy by KO/TKO (-110): Ruffy’s 11 KO/TKO wins and Saint Denis’ defensive lapses make this a high-probability prop.
  2. Under 2.5 Rounds (-140): Both fighters’ finish-heavy records suggest this won’t go the distance.
  3. Ruffy by KO/TKO in Round 2 or 3 (+350): Targeting later rounds offers value, as Saint Denis’ durability may hold up early but crack under Ruffy’s precision.
