Cotto vs Canelo odds: Alvarez the favorite four days out from fight

Canelo Alvarez is not the reigning middleweight champion, and his name doesn't go first on the promotional materials. But he's the betting favorite for his Saturday night HBO pay-per-view showdown with Miguel Cotto, with the odds widening a good bit since the opening lines had him around -200, with Cotto at +160.

Now, the 25-year-old Alvarez (45-1-1, 32 KO) is favored generally around -300, with Cotto (40-4, 33 KO) listed around a +250 to +275 underdog. The 35-year-old Cotto is older and felt to be past his prime by many, though he remains a top fighter and this is without question a fight most see as being competitive on paper, especially as Cotto has won three straight fights in dominant fashion over Delvin Rodriguez, Sergio Martinez, and Daniel Geale.

Alvarez, meanwhile, has also won three straight fights over Alfredo Angulo, Erislandy Lara, and James Kirkland. The Angulo and Kirkland fights were one-sided demolition jobs, while Canelo did struggle somewhat with the Cuban southpaw Lara, though so does everybody, because he's very good.

Here are the odds, courtesy oddsshark.com:

As we've mentioned this week, this would easily be Canelo's biggest win to date, while it would also arguably be the biggest win of Cotto's career, too, as he has come up short in his two biggest fights, challenges against Manny Pacquiao (2009) and Floyd Mayweather (2012).
