Kelvin Gastelum

The result mattered, but so did the context, because he missed weight badly and still had to grind through a full three rounds.

Key moments

• Fought at catchweight after weighing in at 191 pounds.
• Still managed to edge the higher-volume exchanges often enough to win the cards.
• Earned a unanimous decision over three rounds in San Antonio.

Gastelum's durability kept him in the fight, but Pyfer's heavier moments decided the rounds in Newark. Getting dropped twice early forced Gastelum to chase the fight from behind, and while he stayed competitive, he never fully erased the damage deficit Pyfer had created.

Key moments

• Pyfer scored two early knockdowns that framed the fight's scoring dynamic.
• Gastelum stayed tough and competitive but spent the rest of the bout trying to make up ground.
• He lost a unanimous decision after three rounds.

Gastelum's move back up paid off against Rodriguez, who agreed to the middleweight switch after Gastelum struggled with the welterweight cut. Once the fight started, Gastelum looked physically stronger and more comfortable, winning the exchanges often enough to bank a needed three-round decision.

Key moments

• The bout moved to middleweight after Gastelum had issues making 170 pounds.
• Gastelum looked sturdier and more willing to exchange once the weight-cut issue was removed.
• He won a unanimous decision in Riyadh.

Brady made this a grappling fight from the start and Gastelum never found a durable answer to the positional pressure. The submission loss reflected the matchup clearly: Gastelum's boxing never had room to matter because Brady kept dragging the action back to the mat and eventually finished the kimura in round three.

Key moments

• Spent most of the fight defending Brady's takedowns and top control.
• Could not consistently force the bout back into extended boxing exchanges.
• The kimura finish came at 1:43 of round three.

Gastelum's first fight after a long layoff turned into exactly the kind of three-round brawl that still suits him: pocket boxing, constant exchanges and enough variety to keep the judges leaning his way. Curtis had his own moments, but Gastelum's steadier output and willingness to stay in the fire carried him to a deserved decision in a Fight of the Night scrap.

Key moments

• Returned from a layoff of almost 600 days and immediately accepted a high-output striking fight.
• Closed the UFC 287 prelims in a back-and-forth war that earned Fight of the Night.
• Won a unanimous decision over Chris Curtis after three hard rounds.

Gastelum made Cannonier work in the headliner and had useful stretches when he mixed his straight left with takedown threats, but the bigger impact shots came from Cannonier as the fight wore on.

Key moments

• Stayed competitive early by changing levels and forcing Cannonier to react to more than just the left hand.
• Was dropped in the middle rounds as Cannonier's right hand began deciding the fight.
• Lost a unanimous decision by three identical 48-47 scores.

Gastelum never had time to settle because Hermansson attacked the legs almost immediately. Even after briefly reversing the early scramble, Gastelum could not clear the entanglement, and Hermansson locked up the heel hook before the fight ever developed into open space.

Key moments

• Was taken down within the opening minute as Hermansson went straight to a leg attack.
• Briefly improved position but could not fully escape the submission danger.
• Tapped to the heel hook just 1:18 into round one.

The performance itself was a statement win at the time, but it does not count that way historically because the result was later overturned to a no contest after Gastelum tested positive for cannabis in an in-competition sample.

Key moments

• Dropped and finished Belfort with punches at 3:52 of the opening round in the original bout result.
• The win initially looked like a major exclamation point over a former UFC champion in Brazil.
• The bout was later overturned to a no contest after Gastelum's failed in-competition drug test.

The Kennedy fight was an important reset because Gastelum had just lost a Donald Cerrone booking over a bad weight cut and moved up to middleweight under pressure. He answered with one of his better pressure performances, steadily outworking Kennedy on the feet before a third-round barrage produced the stoppage and re-established him as a real threat at 185 pounds.

Key moments

• Moved up to middleweight after the canceled Cerrone bout and fought with a noticeably stronger pace.
• Kept building pressure as the fight wore on instead of fading against the larger veteran.
• Finished Kennedy with punches at 2:45 of round three.

Magny's clinch work, scrambling and volume built an early lead, and although Gastelum rallied hard with two knockdowns in the championship rounds, he still dropped a split decision in a fight that exposed how much work he still had to do in long-form tactical bouts.

Key moments

• Spent the first half of the fight dealing with Magny's clinch control, takedowns and higher volume.
• Rallied late and dropped Magny twice in the fourth round, turning the fight into a tense five-round finish.
• Lost a split decision after 25 minutes in Monterrey.

Gastelum's brief middleweight detour looked far more natural in action than it had on paper, because he mauled Marquardt with pressure, clean southpaw punching and top control in Mexico City.

Key moments

• Pressured Marquardt immediately and mixed combinations with takedowns and positional control.
• Rocked Marquardt late in the first and kept piling up damage through the second round.
• Won by corner stoppage between rounds when Marquardt's team ended the fight after round two.

He kept pressing forward and made the fight competitive, but Woodley's heavier right hand and cleaner impact moments were enough to hand Gastelum a narrow split-decision loss.

Key moments

• The bout was fought at catchweight after Gastelum missed weight badly before UFC 183.
• Stayed aggressive and marched forward, but Woodley produced the cleaner power moments with his right hand.
• Dropped a split decision in the co-main event in Las Vegas.

Gastelum's win over Musoke showed an early version of the problem he would become for established welterweights: he could lose the opening grappling phase, adjust, and then take over with pace and southpaw pressure. After a rough first round against Musoke's size and back takes, Gastelum flipped the fight with body work, combinations and much stronger kickboxing over the final ten minutes.

Key moments

• Survived a difficult first round that included a slam and back-control threats from Musoke.
• Adjusted on the feet and took over with volume, body work and sharper combinations in rounds two and three.
• Won a unanimous decision after rallying from the early grappling deficit.

Gastelum's welterweight debut was short and emphatic. After backing Melancon up with a crisp punching burst that hurt him badly, Gastelum jumped on the opening immediately, took the back and forced the tap with a rear-naked choke before the round was half over.

Key moments

• Made his welterweight debut after winning The Ultimate Fighter at middleweight.
• Rocked Melancon with a sharp combination before following him to the mat.
• Finished the rear-naked choke at 2:26 of the first round.

Gastelum answered with pressure, takedowns and enough control in key moments, especially late in the fight, to grind out the split decision and win the tournament.

Key moments

• Beat the heavily favored Hall to win The Ultimate Fighter 17 tournament.
• Used takedowns and top control to offset Hall's cleaner long-range striking.
• Closed well enough in the pivotal third round to secure the split decision.
