Canelo Alvarez vs Austin Trout reportedly close for May 4

Canelo Alvarez is likely to face Austin Trout in a junior middleweight title unification bout on May 4, according to sources in Mexico (report via BoxingScene.com), in a fight that would be the featured undercard bout on Floyd Mayweather's next pay-per-view card. Mayweather is reportedly going to face Robert Guerrero for the WBC welterweight title.

Alvarez (41-0-1, 30 KO) notched wins over Shane Mosley and Josesito Lopez in 2012, but Trout (26-0, 14 KO) represents an entirely different challenge. The southpaw is a legit 154-pound fighter, in his prime, and just scored a big win over Miguel Cotto on December 1.

Canelo was all but signed and sealed to face Cotto on May 4 before that fight, after which Golden Boy's Richard Schaefer still touted the value of a Canelo-Cotto fight, a story that Alvarez just didn't really accept, as he continually dismissed Cotto as a potential next opponent due to the loss.

If Mayweather-Guerrero and Canelo-Trout goes ahead as seems like for May 4, it's a pretty freakin' good 1-2 punch at the top of a pay-per-view, with a pair of legitimate fights, featuring two big stars taking on contenders who have earned their way into the bouts, brand value be damned.

If Canelo-Trout does go down, who's your pick in that fight? Will Alvarez set up a possible September fight with Mayweather, or can Trout pull off another upset over a more popular foe?
