Victor Ortiz called a potential bout between Floyd Mayweather and Andre Berto “embarrassing” and “not even a fight” earlier this week, and at least one Las Vegas sports book feels a similar way based on the price it’s hung.


Keep in mind, even though both camps said the fight is a go, it’s not official on paper just yet.

South Point has opened Mayweather as a -900 favorite over Berto, who is available at +650. The limit bet is $1,000 right now, and the fight must happen by Sept. 30, 2015, or it will be ruled “no action” and all wagers will be returned. South Point lists the event date as Sept. 12 at MGM Grand Arena in Las Vegas, which has been rumored for several weeks, but not confirmed.

To back Mayweather, a bettor would have to wager $900 to win $100. On Berto, $100 would win $650. Mayweather closed as a favorite of around -200 against Manny Pacquiao in May and won comfortably by decision.

Mayweather has been this big a favorite just once since 2006, a 2014 fight against Marcos Maidana, when he was also -900. In 2005, he was chalk of -950 and -2,000 in a pair of fights.

This will likely be the last fight of Mayweather’s career and with a win, he’d improve to 49-0. His last six fights have gone the distance — his most recent knockout came in the fourth round against Ortiz in 2011. His mastery of defensive boxing doesn’t produce exhilarating fights, but it’s kept him unbeaten and largely untouched since his pro career began in 1996.

Berto is 30-3 with 22 knockouts as a professional. He was 27-0 before dropping three of his last six bouts.
