Sergei Liakhovich (23-1, 14 KOs) won the WBO world heavyweight championship in a very exciting twelve round slugfest over Lamon Brewster (33-3, 29 KOs) Saturday night in Cleveland, Ohio. Both fighters had their moments in a brutal encounter. Liakhovich took a knee to escape a Brewster barrage in the seventh, but he came back to rock Brewster in the ninth and outworked Brewster in the championship rounds to take a 115-113, 115-112, 117-110 victory.
