Cotto vs Martinez: Wilfredo Vazquez Jr vs Marvin Sonsona rematch added to undercard

With so many promotionial companies involved in the workings of the June 7 pay-per-view card headlined by Miguel Cotto and Sergio Martinez, it's taken a little time for the undercard to some together. But now things are coming along as, according to ESPN.com's Dan Rafael, promoter Sampson Lewkowicz told ESPN.com that a fight between Wilfredo Vazquez Jr. and Marvin Sonsona has been made for the undercard. The fight will be a rematch to a bout four years ago when Vasquez knocked out Sonsona in the fourth round.

Sonsona fights under Lewkowicz while Vazquez has recently signed with Cotto Promotions, the promotional company headed up by Miguel Cotto himself. The loss to Vazquez is Sonsona's only blemish, and he is coming off a nice win over Akifumi Shimoda in February.

Vazquez is coming off a victory over Guillermo Avila in September, but has lost three of his previous six fights. Vazquez's most famous fight is also the one that began his downfall. He faced Jorge Arce on the undercard of Manny Pacquiao's fight with Shane Mosley, and the bout stole the show with some wonderful exchanges. Unfortunately for Vazquez, he ended up on the wrong side of too many of them and lost via final round TKO. His three losses also include a split decision to Nonito Donaire in 2012 that should have been unanimous. He gave Donaire a tougher time than expected, though that was more due to his defensive posturing than truly effective fighting.

Does this fight make you any more likely to order Cotto/Martinez, or is the undercard irrelevant because you either love or hate the main event?
