LAS VEGAS — Days before the fight, one Manny Pacquiao believer had already put $500,000 on his man in the MGM Grand sports book.
Now, book operator Jay Rood is working hard to balance the action.
"Hopefully by this evening we'll have taken a million-dollar bet on Mayweather," Rood said Thursday. "We're trying to get that hooked up now."
Big bets and big fights are nothing new in this gambling city. But the richest fight ever is also drawing more money at the betting window than any fight before it.
"The handle on the Strip will be astronomical," Rood said. "It will easily become the biggest fight in Nevada books. I think it could fall somewhere between $60-80 million."
Pacquiao fans have led the way, betting their fighter early and often in most of the city's legal sports books. The influx of money on the underdog has caused odds to drop to less than 2-1 in most books, though some larger Mayweather bets have kept them from falling even more.
Bookies say they expect the betting to rival that of some Super Bowls, fueling a weekend at the sports books like no other as bettors line up to be the fight, the Kentucky Derby and the NBA and NHL playoffs.
"It's amazing. I've never seen so much action so early on a fight," said Johnny Avello, who runs the book at the Wynn resort. "Going back two and a half months this has generated business every day and we haven't even gotten to fight day yet."
