I lean towards Arguello late perhaps by stoppage. Oscar was big for the division and he brings a lot to the table. I don`t trust his stamina especially in the lower divisions. Great fight for about 6 or 7 rounds and then I believe Alexis starts to time DelaHoya and cut down his movement. DelaHoya never had the best stamina over 12 at the lower divisions against an elite opponent he pays the price.
His left and that`s it. Oscar`s right wasn`t much of a weapon. Arguello was the better two handed threat as a puncher.
