Wladimir Klitschko
Wladimir Klitschko (Ukrainian: Володи мир Володи мирович Кличко [Volodymyr Volodymyrovych Klychko]; born 25 March 1976) is a Ukrainian heavyweight professional boxer. Klitschko is the current Transnational Boxing Rankings Board, lineal, WBA (Super), IBF, WBO, IBO and The Ring world champion (see List of heavyweight boxing champions.) Klitschko is the longest reigning IBF, WBA, WBO & IBO heavyweight champion in history with the most title defenses for the IBF, WBO & IBO titles. Overall, he is the second longest reigning Heavyweight Champion of all time with the second most successful career grand total title defenses with 22 (including his "super" title recognition).[citation needed] On 13 October 2013, Boxrec rated Klitschko as the number two pound-for-pound fighter in the world. On 15 December 2014, he reached a career peak of number two on the pound-for-pound list of The Ring. Klitschko is second on the all-time list for most heavyweight title fights with 26, behind only Joe Louis with 27. Since 2005, Klitschko has been the dominant force in the heavyweight division, defeating a majority of the top heavyweights in the rankings. When Klitschko won the IBF title against Chris Byrd there were four separate Heavyweight Champions. Since then, he has unified the IBF, IBO, WBO & WBA belts and defeated the WBA Champion in recess. Following his win over Ruslan Chagaev, Klitschko was awarded the vacant Ring Magazine Heavyweight title. Klitschko has held at least a piece of the heavyweight championship since 2006, when he won the IBF title. The most recent bout in which he claimed a piece of the undisputed title was when he won the WBA championship from David Haye in 2011.[citation needed]
