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.
Klitschko recorded his 53rd KO in 62 wins, with three defeats. Leapai dropped to 30-5, with three draws. In his 25th world championship fight, Klitschko retained his WBA and IBF heavyweight belts, plus the minor WBO and IBO versions.
