Sometimes lightning does strike twice as WBO light flyweight champ Ivan Calderon had his rematch with Rodel Mayol at Coliseo Jose Miguel Agrelot in San Juan, Puerto Rico end early for the same reason as their first pairing in June: a head clash.

One again Calderon was cut badly after a difficult test against the Filipino hard man but this time instead of the technical draw in June, the Guaynabo southpaw came away with a technical decision, winning two scorecards 68-65 while Mayol was awarded the third by the same margin.

Could a third clash between these two be on offer? Calderon has now seen his last three contests end early for the same reason.

Calderon retains the WBO belt for the fifth time and keeps an undefeated career mark of 33-0-1 (6), while Mayol drops to 25-4-1 (19). More...

The hottest ticket in San Juan tonight will be a seat at Coliseo Jose Miguel Agrelot as WBO light fly ruler Ivan Calderon and WBO super feather supremo Roman Martinez put their crowns at risk.

Calderon, 32-0-1 (6), hasn't had a non-title bout in over five years after defending the WBO minimumweight trophy 11 times and his current WBO light fly belt on four occasions.

The 34 year old southpaw rematches big punching Filipino Rodel Mayo, 25-3-1 (19), a former OPBF minimumweight titlist who engaged in a six round TD with Calderon in Madison Square Garden in June when the Puerto Rican hero was cut too badly to continue. More...
