Cotto vs. Canelo 2015 latest odds: Canelo still favored one day from fight

Despite being the challenger and arguably the less proven fighter, Canelo Alvarez is the betting favorite for tomorrow night’s big HBO pay-per-view main event against Miguel Cotto, the reigning middleweight world champion.

Alvarez (45-1-1, 32 KO) has just one career loss, which came to Floyd Mayweather in 2013, but the 25-year-old Mexican standout also doesn’t have a win near as good as one over Cotto (40-4, 33 KO) would be. But the same could be said for Cotto, 35, who has come up short in his two biggest fights to date, against Mayweather in 2012 and Manny Pacquiao in 2009.

Lines opened with Canelo around a -200 favorite to win, and Cotto around +160. Those lines have widened, with Canelo now listed between -250 and -350 on various sportsbooks, according to OddsShark.com. Cotto is now around a +250 underdog on most books, but as low as +195 and as high as +290.

The show is something of a rarity for boxing, though, as the main event is believed to be the second-tightest matchup on the pay-per-view bill. The closest lines are for Takashi Miura’s WBC super featherweight title against Francisco Vargas. Bovada has favorite lines for both Miura (-105) and Vargas (-125), and other books have Vargas around -150 and Miura at +130.

IBF super bantamweight titleholder Randy Caballero is a pretty wide favorite against challenger Lee Haskins, though the lines have narrowed since the opening, where Caballero was listed at -1250. He’s now between -670 and -800, but money has come in on Haskins to score an upset. He’s around +500 now.

Guillermo Rigondeaux, the reigning super bantamweight champion, will face Drian Francisco in a featherweight fight. Cuba’s Rigondeaux, considered one of the most skilled fighters in the world, is a huge favorite, with lines of -1000 and massive -6370 and -7000 odds on various books.
