The champion moved with his hands low and outworked challenger Martin Murray over the first three rounds. Murray picked up his pace in the fourth and outlanded Martinez for the first time in the fight. Martinez was allowed time to recover from a low blow in the round. In Round 6, a cut opened to the outside of Martinez's left eye.
The scored knockdown came in Round 8 when Murray connected with a straight right hand that caught Martinez flushly on the jaw as he was backpedaling and put him on his backside for a couple seconds. Martinez went to the mat again in Round 10 following a glancing punch, but it was ruled by the referee to be a slip.
Through nine rounds, the fight was very close with many having it scored even. The champion, despite complaining of pain in his left hand, outworked Murray in the eleventh and twelfth to claim the win in front of his home crowd.
