LAS VEGAS, NV --  GILBERTO "Zurdo" RAMIREZ, Mexico's undefeated World Boxing Organization (WBO) super middleweight world champion with the matinee idol looks and two-time Mexican Olympian and undefeated No. 1 featherweight contender ÓSCAR VALDEZ, will headline the pay-per-view undercard topped by the junior welterweight world title unification battle between undefeated world champions TERENCE "Bud" CRAWFORD and "The Iceman" VIKTOR POSTOL.

"I really believe that looking at my past few fights I have earned the opportunity to fight for a world championship," said Valdez.  "Now is the time to take advantage of this opportunity."

"Although this will be my second fight in the U.S. and many people might think I am not the favorite, I will surprise lots of fans," said Rueda.  "I respect my opponent, but I am going to Las Vegas determined and with only one thing on my mind – winning the belt and bringing it back to Argentina with me.  You can all be sure of that.  My opponent is going to lose.  I respect him, he is a very good fighter, but he will lose."

 Valdez (20-0, 17 KOs), who represented Mexico in the 2008 and 2012 Olympics, was the first Mexican fighter to qualify for two Olympic games and is considered one of the bright lights of the featherweight division and a new face for boxing's next generation.  In his last fight, on the undercard of the April 9 Pacquiao-Bradley pay-per-view, Valdez solidified his status as the World Boxing Council (WBC) and WBO No. 1 contender by scoring a fourth-round TKO of former IBF featherweight world champion Evgeny Gradovich.  It was the first time Gradovich had ever been stopped in his 24-bout professional career. 

Rueda (26-0, 23 KOs), from Tandil, Buenos Aires, Argentina, enters this world championship fight having won his last 10 fights by way of knockout which he credits to  his exciting "seek and destroy" style and deadly punching power.  He has made six defenses of the WBO Latino featherweight title he captured in 2013 via a third-round knockout of Juan Solis,  On January 16, he also became the South American featherweight champion, scoring an eighth round knockout of Leandro Mendes.  In his last fight, which took place on April 2, Rueda iced Nestor Pamigua in the third round to successfully defend both of his titles.
