Humberto Soto has already vacated his lightweight belt and made his intentions clear, and now he's made his next fight official. The Mexican veteran will face Jose Alfaro in his official move up to the junior welterweight division on September 3 in Los Mochis.
Soto (56-7-2, 32 KO) will likely look to land a charity belt at 140 as soon as possible, which would give him a major title in a third weight class. (Like Jorge Arce currently claiming a bogus four belts, Soto's belt at 126 pounds was an interim title, so even in this world where belts barely mean anything, it doesn't count.)
Alfaro (25-7, 22 KO) is a tough fighter with some pop, but he's proven time and again that he's a good couple of steps below world class in losses to Erik Morales, Antonio DeMarco, Yoshihiro Kamegai, and others. Soto last fought on June 25, defending his WBC lightweight belt for the final time in a fairly lousy matchup with Japanese veteran and current non-contender Motoki Sasaki, which is more or less par for the course for Soto's career as a "champion."
Soto was scheduled to face Urbano Antillon on May 7 in a rematch of Bad Left Hook's 2010 Fight of the Year, but instead ducked out of the fight, and now has no connections at Top Rank, who had helped promote him for years, but hadn't had him under contract in some time. Talk of Soto signing with an American promoter after that news died out rapidly, and he appears content to fight in Mexico for the time being.
