Rafael's remark: Klitschko's remarkable comeback from nearly four years in retirement because of injuries continued with yet another dominant performance against a quality opponent. Klitschko, who came out of retirement to dominate Samuel Peter in October 2008 and regain his old alphabet belt, didn't just retain it for the second time against Arreola. He retained with an authoritative beatdown in one of the best performances of his career. Anyone who was giving Arreola a shot to win (and, be honest, there weren't too many of you) had to be concerned right from the outset. From the moment the bell rang, Klitschko used his long reach, height advantage (6-foot-7 to 6-4) and powerful jab to keep Arreola on the outside when his only real chance to win was to get on the inside and turn it into a brawl. But Klitschko, 38, is too smart and too darned good for that. Instead, he used the jab to control Arreola, who is from nearby Riverside, Calif., and was the favorite of the crowd of 14,556. But Klitschko had some fans, too, given his past history of fights at the Staples Center and the fact that he considers L.A. a second home. Once he had Arreola under control almost exclusively with the jab -- which took maybe a round or two -- he went to work and began teeing off with a variety of punches. A left hook here, a big right there and, oh, how about a mean uppercut and body shot? Klitschko showed an amazing variety of punches in a diverse performance. He looked confident and strong and his legs were better than they've been in ages. It was impressive, especially when you consider Klitschko's age. Arreola, 28, bidding to become the first heavyweight titleholder of Mexican decent, was simply clueless about how to deal with such a big man throwing such big punches from all angles. Out of the 30 combined rounds scored by the three judges, Arreola won only the eighth round on two scorecards. How lopsided was the fight? Judge Guido Cavalieri scored the destructive 10th round 10-8 for Klitschko without the benefit of a knockdown.
