Kevin Lerena TKO3 Serhiy Radchenko... As expected Kevin Lerena retained his WBC 224-pound championship with a third-round technical knockout victory over Ukrainian journeyman Serhiy Radchenko. Fighting in his home country, Lerena pummeled Radchenko in round two, knocking him down three times, although one was ruled to be a slip. Radchenko, a blown-up cruiserweight whose record is now 11-8, clearly had enough after two rounds, shaking his head no to his corner. He was convinced to go out for round three, but when the beating continued, Radchenko's corner threw in the towel. Lerena improves to 31-3.
