Wladimir Klitschko defended his three heavyweight championship belts Saturday with an ugly, yet one-sided victory over Alexander Povetkin of Russia in Moscow.

Klitschko decked Povetkin once in the second round and three times in the seventh, though one of those knockdowns appeared to be a push.

Klitschko won the 12-round bout by three scores of 119-104.

One of the worst parts of the fight was that Klitschko was allowed to get away with constantly initiating clinches and then pushing Povetkin’s head down. Klitschko was allowed to get away with that time after time, round after round.

Interestingly, referee Luis Pabon finally deducted a point from Klitschko in the 11th round for pushing Povetkin down.

Klitschko is 61-3. Povetkin is 26-1.

The fight was televised by HBO and will be replayed later Saturday as part of the Miguel Cotto-Delvin Rodriguez telecast from Orlando, Fla.
