Strickland defeats Chimaev by split decision at UFC 328

Sean Strickland retained the UFC middleweight title with a split-decision victory over Khamzat Chimaev at UFC 328 on May 9, delivering another signature upset performance to cement his place among the division's most unlikely champions.

Strickland, 35, improved to 31-7-0 with the win, continuing a remarkable run that began when he shocked Israel Adesanya to claim the belt. Fighting out of Xtreme Couture, the American operates from an orthodox stance and brings relentless pressure, averaging 6.04 significant strikes per minute with a 76-inch reach. He reportedly broke Chimaev's nose during the contest and controlled large portions of the fight with his trademark output-heavy style.

Chimaev showed his characteristic toughness but faded after the opening round, echoing a pattern seen in his previous outing against Kamaru Usman. The controversial element of the night came via judge Sue Sanidad, a BJJ instructor who last worked UFC events in 2014, who scored the fifth round for Chimaev. The bout was widely viewed as a 3-2 contest for Strickland, making the split verdict rather than a unanimous decision a mild surprise to observers.

Why it matters

• Strickland remains middleweight champion after a second major underdog victory, further solidifying his grip on the division
• Chimaev has signaled interest in moving to light heavyweight, where a matchup with Paulo Costa has been floated as a possibility
• Costa, ranked 13th at middleweight and averaging 6.26 significant strikes per minute at 58 percent accuracy, would represent a high-octane stylistic test at a new weight class
• Strickland's next title defense could come against Nassourdine Imavov, though his reign continues to be framed as potentially brief
