The world heavyweight boxing champion Vladimir Klitschko easily retained his WBO crown when he knocked out Australian Alex Leapai in the fifth round in Germany.
The 38-year-old Klitschko, who holds the WBA, IBF, WBO and IBO crowns, has now been unbeaten for 10 years with his most recent defeat back in April 2004 against Lamon Brewster.
Klitschko knocked down his opponent after a few seconds in the first round, a big left-right combination sending the 34-year-old Leapai sprawling.
The Ukrainian, whose record now stands at 62 wins with 52 knockouts and three defeats, then pummelled the hapless Australian in round five, knocking him down once again before a clean knockout with less than a minute left in the round.
The 34-year-old Leapai, who got a shot at the world title after his stunning win over Russian Denis Boytsov in November last year, never really offered any resistance to the 15-centimetre taller Klitschko, and bowed out quickly.
