(Photo: Esther Lin/Showtime) By Dan Ambrose: In what will probably be the best fight of the card on Saturday night, light welterweight contenders Lucas Matthysse (30-2, 28 KO’s) and Humberto Soto (58-7-2, 34 KO’s) will square off for the vacant WBC Continental Americas light welterweight title on the undercard of the Victor Ortiz vs. Josesito Lopez fight at the Staples Center in Los Angeles, California.

Matthysse, 28, has that advantages of youth, power, speed and size against Sotoa and the only thing that Matthysse has to worry about is the judges. He’s been on the receiving end of two very controversial decisions in the past two years in losses to Zab Judah and Devon Alexander. The defeats have made Matthysse jaded and mistrustful of the judging, which is why he plans on knocking the 32-year-old Soto clean out so that the judges can’t job him.

Matthysse said “I expect to win by KO. I think I was robbed against Zab Judah and Devon Alexander in the United States, so expect a KO. I don’t want it going to the judges on Saturday.”

Can you blame him? Matthysse did more than enough to get wins in both the Judah and Alexander fights, but instead had to live with decision losses in both bouts.

Soto hasn’t looked good in quite some time. It could be age or the wear that he got in his close win over Urbano Antillon. Soto took a lot of head shots in the Antillon fight, and he really had to scrape hard to get a win. The thing is Antillon would be out of his class in a fight against Matthysse. It would be an easy win for Matthysse just as it was with Brandon Rios completely blowing out Antillon.

That right there tells you the difference in talent between Matthysse and Soto. I think Soto is a good fighter, but he’s getting older now and hasn’t fought anyone good in two years, and even then he didn’t perform well. Soto is fighting out of his weight class, and doesn’t have the same kind of power that Matthysse has. I think we’re going to see Soto exposed again like he was in his loss to Joan Guzman in November 2007.
