Heavyweight puncher Chris Arreola (36-3-1, 31KOs) is putting in a lot of hard work for his upcoming rematch with Bermane Stiverne (23-1-1, 20KOs), taking place on May 10th in California and televised on ESPN. Last year, Stiverne won a twelve round unanimous decision over Arreola. The rematch has much higher stakes, as the vacant World Boxing Council (WBC) heavyweight championship will be up for grabs.
