2000-03-18 Diego Corrales w rsc 3 Derrick Gainer, MGM Grand, Las Vegas, Nevada, USA - IBF. Referee: Jay Nady. Although he kept the champion at bay in the opening two rounds, mainly using the jab and throwing harmless flurries, the southpaw Gainer (130) was living on borrowed time as Corrales (130) gradually moved up a gear to close the gap. In the third, Corrales walked in hooking and uppercutting before flooring Gainer with a cracking left hook, and after the latter clambered up and was dropped again, the referee called it off on the 1.50 mark.
On 17 June, at the Staples Centre, Los Angeles, California, Corrales (130) stopped Justin Juuko, weighing 129½lbs, in the tenth round of a contest sanctioned by the IBA, but not the IBF, who had already lined up Arnulfo Castillo as Corrales’ next challenger.
