Ample seating still available for Floyd Mayweather-Andre Berto fight

If this is Floyd Mayweather's last fight, he's going out with a dud at the box office.

With a little more than four days until Mayweather's fight against Andre Berto at the MGM Garden Arena in Las Vegas, Ticketmaster shows there are more than 2,100 seats available -- and that doesn't even count the tickets that are typically held by the promoters.

That's despite the fact that the face value of this fight -- ranging from $125 to $1,500 -- is significantly lower than the prices for Mayweather's fight in May against Manny Pacquiao.

StubHub spokesman Glenn Lehrman said the leading resale site had an average ticket sale price of $5,095 for Mayweather's fight against Pacquiao, while the average sale for Saturday's fight is more than six times less ($799). As of 10 a.m. ET on Tuesday morning, only 25 seats to the Mayweather-Berto fight had been sold for more than $1,000 on StubHub.

In fact, the site has done a bigger business on the Anthony Joshua-Gary Cornish fight in London on Saturday than Mayweather-Berto.

While hotels in town had raised their prices to more than four times their normal rates for the Mayweather-Pacquiao fight, there has been no bump for Mayweather-Berto.

Late last week, as ticket sales halted, MGM Hotels started offering more aggressive deals to those who have frequently stayed at their properties. One offer was $1,000 for a two-night stay at the MGM Grand that included two Mayweather-Berto tickets.

The lack of interest in Mayweather's opponent is understandable. Berto has lost three of his last six fights, and many don't believe that this, Mayweather's 49th fight, will be his last because another win after this would allow him to pass Rocky Marciano's record of 49-0.

"This is 100 percent his last fight," Mayweather Promotions CEO Leonard Ellerbe reiterated to ESPN.com on Tuesday.

Still, gamblers aren't particular intrigued with Mayweather-Berto either. In order to win $1 at the Wynn Sports Book, a bettor favoring Mayweather to win would have to risk $35.
