The fight that "made" Donaire in many ways was huge huge upset win over the then unbeaten and much feared Vic Darchinyan. Going into the fight Darchinyan was 28-0 (22) he had been the IBF champion for close to 3 years and had stopped 9 of his previous 10 opponents, including the likes of Irene Pacheco, Luis Maldonado and Jose Victor Bugors. The only one of those 10 opponents who wasn't stopped was Glenn Donaire, who lost a 6th round technical decision to the free swinging champion.
Glenn was Nonito's brother and although Darchinyan easily defeat Glenn he couldn't stop Nonito getting revenge and scoring one of the biggest upsets of the last 20 years with a stunning devastating KO that really put Donaire on the boxing map.
