I didn't realize Merchant was over 70 when he threw that right hand at that guy- that was a pretty good punch. I saw Zaragoza win a world title in his second fight with Cermeno, I think it was.
Arroyo put in a lot of effort and patience setting up the right hand that started the end for Alli.
Palomino dropped that split to benitez, and he lost to Duran. His only other two losses were to Andy price, who had been a top amateur and was a solid pro, early in his career; and he lost to Wilfredo Rivera when he was 49. Top quality fighter.
