LOS ANGELES -- UFC champion Ronda Rousey trumped Floyd Mayweather and then called him out on the carpet.

Rousey was awarded the Best Fighter ESPY on Wednesday during ESPN's preshow red-carpet coverage, beating out the pound-for-pound boxing champion despite Mayweather's historic victory in May over Manny Pacquiao.

Rousey, in accepting the award, said she wondered how Mayweather felt about getting "beat by a woman for once."

Mayweather has drawn headlines outside the ring for years over multiple domestic violence incidents and arrests.

"I'd like to see you pretend not to know who I am now," Rousey said, referring to a controversial interview in which Mayweather, when asked whether he could beat her in a fight, said he wasn't familiar with Rousey.

Rousey later took home the Best Female Athlete ESPY, topping Serena Williams, skier Lindsey Vonn and Connecticut's three-time NCAA women's basketball champion Breanna Stewart for the award.

Rousey thanked her mother in her acceptance speech before saying, "I'm living such a lucky and blessed life, and I'm trying my best to deserve it."

Rousey (11-0), who is scheduled to fight the undefeated Brazilian Bethe Correia on Aug. 1 in Rio de Janeiro, is coming off a 14-second submission win against Cat Zingano at UFC 184 on Feb. 28.

It was Rousey's fifth title defense and the quickest finish ever in a UFC title fight.

Fan voting for the 23rd annual ESPYS was conducted online and based on performances spanning the past 12 months.

The ESPYS was hosted by actor Joel McHale as top celebrities from sports and entertainment gathered to commemorate the past year in sports.
