In front of a sold-out hometown crowd, WBC/WBO middleweight world champion Kelly Pavlik (35-1, 31 KOs) dominated WBC mandatory challenger Marco Antonio Rubio (43-5-1, 37 KOs) over nine rounds on Saturday night at the Chevrolet Centre in Youngstown, Ohio. Pavlik had a strong start, landing some big shots in the first few rounds. Rubio continued to be on the receiving end as Pavlik initiated all the offense. Rubio became more competitive in round six, but Pavlik had a big round eight landing some big right hands and continued to punish Rubio in the ninth. Rubio quit on his stool before round ten began.
