American Shakur Stevenson stopped compatriot Jamel Herring in the 10th round to win the WBO super-featherweight title in Atlanta.

Stevenson’s power and speed were too much for Herring who cut his eye in the ninth, before the referee stepped in.

“I wanted to show everything tonight,” said Stevenson.

“I wanted a fun fight: show my skills, my boxing, my power.”

The Olympic silver medallist and former featherweight champion, who is now unbeaten in 17 professional fights, added: “I want to be a superstar in the sport; I’m here to last.”

The defeat was Herring’s third loss in 26 fights while this was Stevenson’s ninth knockout of his career.

Ali’s grandson wins second fight

On the undercard, Muhammad Ali’s grandson Nico Ali Walsh won his second professional fight with a third-round knockout of James Westley II in their middleweight contest.

Ali Walsh, 21, took some blows early on but dropped Westley in the second round before Westley’s corner ended the contest after another knockdown early in the third.

“I’m blessed that I’m following the legacy of my grandfather,” said Ali Walsh, who made his debut in August.

“I think everyone who loves my grandfather who’s watching me… I love this legacy that I’m continuing.”
