Willie ‘Big Bang’ Casey proved no match for classy Guillermo Rigondeaux in their WBA interim super-bantamweight title fight at Citywest in Dublin on Saturday.

Rigondeaux, who won gold at the 2000 and 2004 Olympic Games, wrapped up an utterly convincing win in just two minutes and 38 when veteran referee Stanley Christodolou stopped the bout. The official verdict was a technical knockout.

Rigondeaux rocked Casey after just a minute with a flurry of body punches. The Limerick fighter visibly winced, such was the ferocity of the attack.

That early move paved the way for what was a facile victory.

Rigondeaux knocked Casey to the Canvas moments later with a vicious left hook.

The tenacious 29-year-old was soon back on his feet, but another haymaker of a left hook downed the man dubbed ‘Big Bang’ for a second time. The 29-year-old returned for more after a standing count, but Christodolou has little option but to intervene after Casey sustained another barrage of blows to the head.

There only ever looked like being one winner in this battle of the southpaws, and the two-time Olympic champ demonstrated that guts and a will to win are no substitutes for experience and ability at this level.
