PRESS RELEASE: It’s not unusual for boxers to call out opponents, but World Boxing Association welterweight champion Luis Collazo has taken this tradition one step further by officially signing contracts to face “Pretty Boy” Floyd Mayweather, Carlos “Tata” Baldomir, “Sugar” Shane Mosley, Miguel Cotto, Arturo “Thunder” Gatti and Antonio Margarito. Collazo made a special trip on Friday to visit his promoter, Don King, to affix his signature on the bottom line of six contracts. I am serving notice on the other champions and contenders in and around the welterweight division that I am ready and willing to defend my title against anyone,” the brash Collazo said.  “My signature is on the bottom of six contracts.  Now let’s see who really wants to fight. Collazo won the WBA crown by winning a decision over Jose Antonio Rivera in Rivera’s hometown of Worcester, Mass., on April 2, 2005.  He successfully defended his title by defeating ring legend Miguel Angel Gonzalez by eighth-round technical knockout in Las Vegas on Aug. 13 in Chicago. "Collazo means business with this proclamation,” King said.  “Luis has dropped the gauntlet on the division.”
