Castillo tried to use his wrestling early and take Pettis down, but the two quickly returned to their feet, where Castillo quickly found himself in trouble. Pettis knocked Castillo down with a straight right and then a towering left kick to the head. He followed up with a few punches that knocked Castillo clean out. "This fight was important, I had a loss and some injuries," Pettis said after the bout. "Did you like that knockout? I got more like that." More... Yahoo! Sports.
