The World heavyweight boxing champion Wladimir Klitschko defended his WBA, WBO, IBF and IBO belts beating challenger Francesco Pianeta with a sixth-round knockout to register the 60th win of his career.
Although Pianeta, who survived testicular cancer three years ago, came into the bout undefeated from 29 fights, he was outclassed by the 37-year-old Klitschko at Mannheim in south-west Germany.
For his next bout, Klitschko has been ordered by the World Boxing Association to fight Russia's Alexander Povetkin in Moscow in August.
