Kamaru Usman defeated Colby Covington by unanimous decision to retain the UFC welterweight championship at UFC 268 in New York on Sunday.

With the win, Usman improved to 20-1-0, and has won 19 fights in a row, including five title defenses.

“I am the pound-for-pound best alive right now,” he said.

Covington, the former interim welterweight champion, dropped to 16-3-0.

New York State Athletic Commission judges Derek Cleary (49-46), Dave Tirelli (48-47) and Sal D’Amato (48-47) all submitted scorecards in Usman’s favor.

Going into the fight, Covington said he had recalibrated his approach and would not fight the same way as he did in their first encounter. And the beginning of the opening round revealed a more cautious fighter, though as the round progressed, Usman’s pressure appeared to force Covington into a defensive posture.

Usman got the first knockdown of the fight late in the second round, and attempted to finish Covington with a flurry of punches before the bell rang. He started the third round where he left off, but Covington finished the five minutes by having Usman pinned against the cage.

The two spent much of the fourth and fifth rounds exchanging strikes. Covington staggered Usman with a shot in the fifth, but was unable to put him away.

Usman and Covington headlined the fifth UFC pay-per-view event at Madison Square Garden, and had a pair of rematches in the co-main event and main event.

The Usman-Covington fight was a rematch of their classic title bout at UFC 245. Usman won that five-round, stand-up battle with a technical knockout of Covington with 50 seconds left in the fifth round, although Covington immediately protested referee Marc Goddard’s decision, and continued to grouse about the call in the 22 months since the fight.

There was no such controversy in the first Rose Namajunas-Zhang Weili women’s strawweight title fight, as Namajunas knocked out Weili 1:18 into the first round in their UFC 261 bout in April to retain her title.

Seven months later, the result was the same for Namajunas, even if the path she and Weili trode was unfamiliar. Following a five-round jiujitsu exhibition, Namajunas defeated Weili via split decision in the co-main event.

Judge Michael Bell submitted a 48-47 scorecard for Weili, while Eric Colon (49-46) and Doug Crosby (48-47) had Namajunas winning the fight.

“It was different,” said Namajunas, who was serenaded by chants of “USA” and “Let’s Go Rose” by the partisan crowd throughout the fight. “I was pretty confident in the end I won it.”
