LOS ANGELES — Vitali Klitschko pounded Cris Arreola almost at will Saturday night, retaining his heavyweight title when the referee waved the fight to a close after the 10th round.

Klitschko dominated from the opening bell, landing punches from almost every angle against Arreola, who was trying to become the first Mexican-American to win a piece of the heavyweight title. It was his third win since returning to the ring last year after a four-year retirement.

Arreola pressed the action nearly the entire fight against the bigger and more versatile Klitschko, but paid a price. He landed an occasional punch, but took plenty of punishment every time.

Klitschko moved to 38-2, while Arreola lost for the first time in 28 fights.
