LAS VEGAS – The money generated by the Floyd Mayweather Jr.-Manny Pacquiao fight extends to the betting windows.

Jay Rood, vice president of race and sports books for MGM Resorts, said the fight on Saturday will break all records in terms of money wagered on a single fight at the hotel.

No. 1 at the time Rood was interviewed Thursday afternoon was the fight between Mayweather and Canelo Alvarez in 2013 but he was certain that Mayweather-Pacquiao would pass Mayweather-Alvarez and set new standards.

“It sits about third right now,” Rood said. “By the time I get back to my office, it could be No. 2. It’ll definitely be No. 1. No. 1 was Mayweather-Canelo, No. 2 Pacquiao-(Miguel) Cotto. And 3 and 4 are Pacquiao fights.”

Rood said it’s policy not to reveal the specific amounts wagered per fight at the hotel. However, statewide, he estimated that $20 million to $25 million was wagered on Mayweather-Alvarez.

Mayweather-Pacquiao? “Somewhere between $60 (million) and $80 million,” he said.

As of Thursday afternoon, Mayweather was -200 to win; Pacquiao +170. That means Mayweather was roughly a 2-1 favorite.
