Mayweather vs. Mosley Fight: Odds Slashed for Floyd

With the much anticipated Mayweather vs. Mosley fight taking place at 9 pm EST in Las Vegas this evening, odds have gotten more fluid as action continues to pour in.

Floyd Mayweather was close to a -500 favorite and the line had dropped all the way down to -400 at Sports Interaction.com prior to 6 pm EST.

"These are some of the best odds we've gotten on Mayweather in weeks," said Don Shapiro of Gambling911.com.

Shane Mosley would pay almost $300 for every $100 bet or $30 for every $10 bet with an upset.

From Chris Mannix at CNNSI.com:

Love him or hate him -- and judging by the mixed reaction Mayweather received at Friday's weigh-in before his welterweight fight with Shane Mosley at the MGM Grand (9 p.m. ET, HBO PPV), there are droves of people on both sides of the aisle -- everyone does want to watch him. With 5.5 million pay-per-view buys, Mayweather is one of the most prolific pay-per-view fighters of all time, grossing $292 million in six PPV fights, the kind of numbers that serve to feed his ego.

"I got respect for Sugar Ray Robinson," said Mayweather. "I got respect for Muhammad Ali. But I'm a man, just like they are men. What makes them better than I am? Because they fought a thousand fights? In my era, it's totally different. It's pay per view now, so things change. It's out with the old and in with the new. Like I said, Ali is one hell of a fighter. But Floyd Mayweather is the best. Sugar Ray Robinson is one hell of a fighter. But Floyd Mayweather is the best."

Why the line is dropping remains a bit of a mystery.  Most of the action is coming in on Mayweather.  Slashing the odds gets even more money on Mayweather.

The Mayweather vs. Mosley fight completes what looks to be a record setting day in terms of betting, which kicked off with the 2010 Kentucky Derby.
