They don't call Floyd Mayweather Jr. "Money" for nothing.

Mayweather's junior middleweight title victory against Miguel Cotto on HBO PPV last Saturday night at the MGM Grand in Las Vegas generated a whopping 1.5 million pay-per-view buys and $94 million in domestic pay-per-view revenue, HBO Sports announced Friday.

The performance ranks as the second-highest grossing pay-per-view for a non-heavyweight fight in history.

No. 1 all-time remains Mayweather's 2007 victory against Oscar De La Hoya, in which he also claimed a junior middleweight belt. That fight generated all-time records for any weight class with 2.46 million buys and $137 million in pay-per-view revenue.

The 1.5 million figure for Mayweather-Cotto will grow once all of the numbers are accounted for, according to Golden Boy CEO Richard Schaefer, who promoted the fight with Mayweather Promotions.

"The 1.5 million number is actual reported numbers," Schaefer told ESPN.com. "The final number will definitely be bigger than what it is now."

In nine HBO PPV main events, Mayweather has generated 9.6 million buys and $543 million in television revenue, according to HBO.

Mayweather-Cotto moved past Mayweather's 2010 victory against Shane Mosley, which did 1.4 million buys and $78 million in revenue. Mayweather's knockout of Victor Ortiz in September sold 1.25 million subscriptions and generated $78.4 million. The higher revenue for the Ortiz fight is because the cost of the pay-per-view was higher.

"Floyd Mayweather's numbers are getting bigger and bigger and this number shows you the kind of draw he is," Schaefer said. "He's a superstar and able to capture the interest of a large audience. He has broken out of the boxing following and now has a mainstream following that is unmatched in the sport. The numbers keep getting bigger and bigger."

According to the Nevada State Athletic Commission, Mayweather-Cotto also had the ninth-biggest gate in state history, generating $12,000,150 from 14,612 tickets sold.

HBO will replay Mayweather's decision victory against Cotto on Saturday night, along with junior middleweight titlist Saul "Canelo" Alvarez's decision win against Shane Mosley, which was the co-feature of the card.
