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...

At stake was the WBO Light Flyweight title held by Calderon since jumping up from minimumweight last year.

37 year old Dieppa had held the title in the earlier part of the decade but had it removed by Mexican slugger Hugo Fidel Cazares in 2005 and failed a year later to reclaim the belt in a rematch. Since then the Vieques natives had gone 1-1 and was looking to right his flagging career with a win over Calderon.

But it was not in the cards last night for Dieppa as Calderon was on point from start to finish, beating the older man to the punch with his fast hands flowing from a southpaw stance. Utilizing cat-quick reflexes and superb footwork, Calderon never let Dieppa in the bout and cruised to a dominating 120-108 verdict on all three scorecards. More...
