Wladimir Klitschko retained his WBA and IBF heavyweight titles Saturday night in Moscow, unanimously outpointing previously undefeated Alexander Povetkin. Klitschko knocked down Povetkin three times in the seventh round. All three judges ruled 119-104 for Klitschko (61-3). Povetkin lost for the first time in 27 fights. Klitschko stuck to his usual tactics, scoring frequently off his left jab and forcing Povetkin to attack, but the Russian rarely succeeded. Klitschko first knocked Povetkin down with a combination 51 seconds into the seventh round. He floored Povetkin again with a left hook 35 seconds later, and again with 57 second left, but the Russian recovered.
