2004-03-06 Diego Corrales w pts 12 Joel Casamayor, Foxwoods Resort Casino, Uncasville, Connecticut, USA - WBO. Referee: Steve Smoger. Scorecards: 115-112, 115-112, 113-114. Contesting the title left vacant when Acelino Freitas relinquished it was Corrales (130) who made the early running with good stiff jabs finding their mark, backed up by solid rights, while Casamayor (130) posed too much without really taking off. Eventually realising he was not doing enough the Cuban southpaw began to raise his game, with straight lefts beginning to hurt Corrales, and in the ninth a solid left dropped the latter for the only knockdown of the fight. It was now nearly all Casamayor, but Corrales held on during a few sticky moments before coming back well in the 11th when two heavy rights hurt Casamayor. At the final bell it was certainly a tough one to call, but after winning six of the first seven rounds the split decision ultimately went in favour of Corrales, who also won the 11th.
In a fight to decide the vacant ‘interim’ title on 15 July at the American Airlines Arena, Dallas, Texas, Mike Anchondo outpointed Julio Pablo Chacon over 12 rounds, before being upgraded to full championship status when Corrales vacated the title on winning the WBO lightweight crown on 7 August.
Later, on 8 April 2005, at the Miccosukee Indian Gaming Resort, Miami, Florida, Anchondo (134½) failed to make the weight for a defence against Jorge Barrios (128½), who was awarded the title following a fourth-round stoppage win after the fight went ahead.
