Floyd Mayweather's bout vs. Berto shaping up to be a box-office flop

If Floyd Mayweather's fight against Andre Berto is really his last, there will be few in attendance to witness it.

Ticket sales suggest that there is little interest surrounding Saturday's match at the MGM Garden Arena in Las Vegas as compared to the fight between Mayweather and Manny Pacquiao in May.

While tickets for Mayweather-Pacquiao were hard to come by in the days before the fight, four days before the match with Berto, there are more than 2,100 seats available on Ticketmaster with only four days left, according to ESPN's Darren Rovell.

It is not the price of the tickets that is keeping them from moving. Ticket prices range from $125 to $1,500, significantly less than the bout with Pacquiao. While the average ticket sale price on Stubhub was $5,095 for the Mayweather-Pacquiao fight, the average sale for the Mayweather-Berto fight is $799, more than six times less, according to company spokesman Glenn Lehrman.

According to ESPN, MGM Hotels started offering deals for patrons who were frequent visitors at their hotels, including an offer that includes two Mayweather-Berto tickets and a two-night stay at the MGM Grand for $1,000.

Berto is not exactly the fighter that many saw Mayweather ending his career with, with little buzz surrounding him. Berto is 30-3 with 23 KOs in his career.

Saturday will be Mayweather's 49th fight. A win on Saturday would allow him to retire at 49-0, tying the record with Rocky Marciano.
