"Sugar" Shane Mosley returns to the division in which he was most successful and which made him a pound-for-pound king, as he takes on David Estrada this Saturday night on ESPN's first pay-per-view show at Caesar's Palace in Las Vegas.

After leapfrogging from 130 to 147 to defeat Oscar De La Hoya for the welterweight crown in 2000, Mosley defended against Antonio Diaz, Adran Stone, and Shannon Taylor, winning all by stoppages before losing twice to Vernon Forrest in 2002. After debuting at junior middlweight with a no-contest against Raul Marquez and with his stock at an all-time low, Mosley pulled out another victory over De La Hoya in their rematch at 154 before losing twice to that division's top dog, Ronald "Winky" Wright, thereby destroying a potential superfight with Felix Trinidad. Instead, Wright will fight Trinidad in May, while Mosley goes back down in weight.

Regarded as even a small welterweight, "Sugar" Shane was clearly in over his head at junior middle. Although his second fight with Wright (his first with new trainer Joe Goosen) was competitiive and close, Mosley fought as a flat-footed puncher at 154 against bigger men. Will a return to 147 bring out the lightning-quick, fleet-footed, combination-throwing Mosley of the past?

Mosley is 1-4-1 in his last six fights. Before the two losses to Forrest, his last two fights at 147, his record was a sparkling 38-0 (35). Mosley was a sensational lightweight, but still posessed plenty of power 12 pounds north of that weight. Estrada, 18-1 (9), is trained by the legendary Angelo Dundee, and the two recently appeared on an episode of ESPN's Friday Night Fight's claiming to have the perfect strategy to defeat Mosley. But if Mosley retains even a fraction of his former self at welterweight, it's hard to imagine anyone outboxing him. And if he makes the weight without any problems and without weakening himself, he should still have plenty of pop to give Estrada soemthing to think about.

Can "Sugar" Shane reclaim his past fame? It all depends on whether he beats Estrada, and how good he looks doing it.

Prediction: Mosley KO 6

Though Mosley is the biggest name on the card, the ESPN show is actually being headlined by a welterweight bout that should be a real gunslinger - Antonio Margarito vs. Kermit Cintron.

Margarito, 31-4 (22), is coming off a sloppy but impressive win over Sebastian Lujan, a bout which was featured on ESPN, where broadcaster Joe Tessitore went a little overboard in trying to hype the PPV event, claiming Margarito could be a threat to Oscar De La Hoya. Though Zab Judah is the top welterweight, Margarito has been impressive and probably deseves his number 1 ranking by "The Ring" magazine.

Cintron, 24-0 (22), while not as experienced as the Mexican Margarito, has far better boxing skills and crippling power in both hands. The Puerto Rican native who fights out of Reading, Pennsylvania looked great in his KO victory over Teddy Reid last year and like Miguel Cotto a division below, is being compared to Felix Trinidad. Cintron's chin has not been tested and he is not as defensively sound as Cotto, but this bout is not as even as the heads at ESPN is making it out to be; Cintron will expose Margarito as a "Mayorga lite"; that is, a big-punching, over-hyped fighter with rudimentary skills.

Look for Cintron to use his jab and long right hand to land frequently on Margarito's face. Margarito will get his own shots in, and if Cintron takes them well, that's bad news for Margarito.

Prediction: Cintron KO 5
