Oxnard junior middleweight prospect Hugo Centeno started fast in his Showtime Extreme featured bout tonight on the Guerrero-Aydin undercard, but he couldn't hold that pace. Still, he wound up winning an easy decision on scores of 80-72, 80-72, and 79-73, facing an opponent who alternately couldn't and wouldn't do much at all. Bad Left Hook scored it 79-71 for Centeno.

[ Live Coverage: Guerrero vs Aydin ]

Centeno, 21, has a 6'1" frame and some genuine talent, but he also showed some stamina problems tonight, as he came out blazing but sputtered out down the stretch, with his output dropping considerably, and his body showing clear signs of fatigue through the last few rounds.

Still, a win is a win, and the young man has plenty of time left to go in the sport to improve and learn. Apart from the stamina, his biggest issue tonight seemed to be a lack of real thump on his punches. That can be changed, too. Again, plenty of time to learn.

Bruce falls to 22-8 (14 KO) with the loss, and probably won't be getting TV spots again any time soon.
