Action Heroes Update: Robert Guerrero Dominates Michael Katsidis Over 12

Michael Katsidis gave his usual game effort, but tonight it started getting even harder to watch, as Robert Guerrero battered the Aussie brawler for most of their 12 rounds together, winning a wide unanimous decision in the main co-feature at the MGM Grand.

Guerrero (29-1-1, 18 KO) won on scores of 118-106, 118-107 and 117-108. Bad Left Hook scored it 117-108 for Guerrero.

Katsidis (27-4, 22 KO) is looking more and more like a double tough opponent. Frankly, his pressure fighting skills have eroded, and in many rounds he was not only beaten up and eating clean, heavy blows, but getting thoroughly outworked, too. Katsidis had two points deducted for low blows, but one of those came back when Guerrero got the same deduction the next round.

Guerrero is being hyped up as the next challenger for lightweight king Juan Manuel Marquez, and you can definitely count me in as a supporter of that matchup. When Guerrero is on his game, as he was tonight, he is a terrific fighter. He looks big and strong at 135, like he could go up higher, and he dominated this fight. Katsidis is a wonderful guy and no fight fan dislikes him, but his body is betraying him, and that's not going to reverse itself.
