SAN JUAN, Puerto Rico (September 9, 2009) – “Undefeated Champions” is the name of the card that will feature world champions Iván “Iron Boy” Calderón and Román “Rocky” Martínez in title defenses this Saturday night (September 12), presented by PR Best Promotions, live on pay per view from the Coliseo de Puerto Rico José Miguel Agrelot in San Juan.

At yesterday’s press conference in San Juan, WBO junior flyweight champion Calderon (32-0-1, 6 KO’s) showed he was confident of defeating Rodel Mayol (25-3-1, 19 KO’s) in their rematch of the June 13 bout, when an accidental head-butt caused a cut to Calderon’s head and ended the fight in a technical draw.

“You will see the old Calderon,” Calderon said, “the slick and fast Calderon.”

“I know that I will win this fight,” Mayol countered. “I’m prepared to do that and you will see Saturday.”

Meanwhile, WBO junior lightweight champion Martinez (22-0-1, 13 KO’s) will defend his belt against Argentinean Vicente Martin Rodriguez (25-2-1, 13KO’s), who is scheduled to arrive tomorrow in Puerto Rico.
