OBERHAUSEN, Germany (AP) -- Wladimir Klitschko toyed with Alex Leapai and knocked him out in the fifth round to retain his four heavyweight belts on Saturday.
Klitschko, taller with a longer reach, controlled the fight at will, scoring with left jabs and straight rights with hardly any opposition from the Samoan-born Australian.
Leapai went down when he was hit with a left-right combination. He got up but Klitschko put him away for good with 58 seconds left in the fifth.
"Glory to Ukraine," Klitschko said after his one-sided win.
