Ramirez showed his power in the second, dropping Hart before generally battering him for the majority of the round. Ramirez had another big round in the fourth before Hart showed a willingness to try and make it a more competitive contest.

Both men landed big shots in the final round, the Mexican retaining his crown via scores of 115-112, 115-112, 114-113.
