I highly doubt Corrales fears Cas,but maybe he was a bit apprehensive to fight him a third time. The first fight was close because Casamayor was allowing it to be by trying to outbrawl Corrales but towards the end of the fight,Corrales was gaining the upperhand. As for the second fight,Joel made it close with the knockdown but there is no way you can say he won,a draw at best. He took waaaaaaay too long to get started and Chico outboxed him for long periods.
