The fight was a one-sided affair. Ruiz was outboxing Serin in the first four round rounds. During the fifth, Ruiz suffered a bad cut near his left eye and it was bleeding bad for the rest of the fight. Ruiz picked up the pace in the sixth and began to batter Serin. During the seventh, Ruiz was blasting Serin with punches against the ropes. The ref stepped in and gave Serin a standing standing eight count. Ruiz continued to batter him when Serin's corner threw in the towel.
