Mannheim (Germany), May 5 (IANS/RIA Novosti) Wladimir Klitschko retained his four heavyweight titles by winning a voluntary defence bout against Italian challenger Francesco Pianeta with a sixth-round knockout here.
KlitschkoÂ’s record improved to 60-3 Saturday with all but eight of those wins by knockout while Pianeta suffered his first defeat in 29 fights.
The Ukrainian Â‘superÂ’ champion now has to fight WBA Â‘regularÂ’ champion, Russian heavyweight Alexander Povetkin, in order to leave just a single WBA belt-holder.
Povetkin has a voluntary title defence bout against PolandÂ’s Andrzej Wawrzyk May 17 at MoscowÂ’s Crocus City Hall. The Russian boxer is most likely to win the fight against his outclassed challenger, experts believe.
Povetkin has won all of his 25 professional fights, with 17 knockout wins.
According to WBA rules, the Klitschko-Povetkin bout must take place by the end of August.
