Score this round 10-9 for Ronda Rousey.
On Wednesday, Rousey, the UFC women's bantamweight champion, fired back at Floyd Mayweather for comments the champion boxer made disparaging the purse splits between the two fighters.
"It's kind of funny, people bring up pay to me a lot," Rousey said to TMZ. "I don't know if you saw the Floyd thing. He said, ‘when you make $300 million in a night, then you can give me a call.' And I actually did the math, and given the numbers of my last fight, I'm actually the highest paid UFC fighter, and I'm a woman.
"I think I actually make two to three times more than he does per second. So when he learns to read and write, he can text me."
The verbal salvo marked the latest chapter of the continuing public spat between Rousey and Mayweather, both of whom are considered to be among the most dominant athletes in their respective sports.
After winning the ESPY for Fighter of the Year in July, Rousey pointed to Mayweather's troubled history of domestic violence, quipping, "I wonder how Floyd feels being beaten by a woman for once."
The statement drew a response from Mayweather several weeks later on SportsCenter.
"I've yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes," Mayweather said. "When she can do that, then call me."
Both Rousey (12-0) and Mayweather (48-0) are undefeated in their professional fighting careers. Mayweather shattered the record for fighter purses this past May when he defeated Manny Pacquiao in an anticlimactic match that became the highest-selling pay-per-view of all-time.
Rousey, meanwhile, has proven to be one of the biggest stars the UFC has seen since Brock Lesnar.
Her 34-second knockout of Bethe Correia at UFC 190 drew unexpectedly huge pay-per-view interest despite being supported by a relatively weak undercard. Combined, her last three fights have ended in just 64 seconds, leading her to poke at the dollar-per-second figures splits between her and Mayweather.
"I'm just a little bit more efficient," Rousey said, smiling.
