Anthony Joshua wasn’t spectacular Saturday night, but the former heavyweight champion comfortably got back to his winning ways with another new trainer, Derrick James, in his corner.

The British superstar was workmanlike in out-landing American Jermaine Franklin during their 12-round main event at O2 Arena in London. Judges Steve Gray (118-111), Fabian Guggenheim (117-111) and Alex Levin (117-111) all credited Joshua for a convincing victory over Franklin in a fight DAZN streamed worldwide.

Watford’s Joshua (25-3, 22 KOs), who entered the ring as at least a 10-1 favorite according to most sportsbooks, said before he faced Franklin (21-2, 14 KOs) that he would retire if Franklin defeated him.

“It was important to get the win,” Joshua told DAZN’s Ade Oladipo in his post-fight interview. “You see, Jermaine’s got – someone else will knock him out, probably, from Britain, I reckon. But Jermaine’s got a good duck-and-dive style. There was opportunities there, but he knew how to tuck up. Respect to him – he done well. He done well. I respect him for that. Well done to him and his team for preparing. They were very well prepared for the fight. I shoulda knocked him out, but what can I say now? It’s done. On to the next.”

The 6-foot-6, 255-pound Joshua looked tentative at times and initiated numerous clinches, but he clearly landed the more impactful punches, most notably right uppercuts, on his shorter opponent. CompuBox credited Joshua for landing more than twice as many punches overall than Franklin (117-of-376 to 58-of-246), including 23 more power punches (60-37) and 36 more jabs (57-21).

Joshua, 33, won a fight for the first time since December 2020, when he knocked out Kubrat Pulev in the ninth round. The former IBF, IBO, WBA and WBO champion lost his previous two fights to Oleksandr Usyk.

The unbeaten Ukrainian southpaw upset Joshua by unanimous decision in their 12-rounder in September 2021 at Tottenham Hotspur Stadium in London. Usyk then out-pointed Joshua by split decision in their 12-round rematch, which took place last August 20 at Jeddah Superdome in Jeddah, Saudi Arabia.

The 29-year-old Franklin fought competitively in his prior appearance – a 12-round, majority-decision defeat to Dillian Whyte on November 26 at OVO Arena Wembley in London. The Saginaw, Michigan native came in 22-plus pounds lighter for this bout, but he wasn’t as competitive against Joshua as he was with Whyte (29-3, 19 KOs).

Franklin didn’t exhibit enough power to affect Joshua, but he clearly needed a knockout to win entering the 12th round.
