LAS VEGAS (AP) — Floyd Mayweather Jr. will fight a rematch Sept. 13 with Marcos Maidana, the Argentinian who gave him a tougher battle than expected when they met in May.

Mayweather announced Thursday that Maidana would get a rematch in a pay-per-view fight from the MGM Grand hotel-casino. Mayweather won the first fight between the two by majority decision, but Maidana was given credit for taking the fight to the undefeated welterweight champion.

Maidana said after the fight he thought he won, and that Mayweather never hurt him. “He wasn’t that tough,” Maidana said.

Punch stats showed Mayweather landing 230 of 426 punches to 221 of 858 for Maidana. It was the most punches landed by any fighter against Mayweather in 38 fights where punch stats were compiled.

Mayweather is 46-0 with 26 knockouts and Maidana is 35-4 with 31 knockouts. The fight will be promoted by Golden Boy Promotions.
