Argenis Mendez knocked out Juan Carlos Salgado in the fourth round tonight in Costa Mesa, California, winning the IBF super featherweight in a rematch of a very close 2011 bout.

Mendez (21-2, 11 KO) was once a highly-touted prospect out of Brooklyn by way of the Dominican Republic, but a loss in 2008 derailed him a bit. Now, it appears the 26-year-old has started to really put it together, because he was able to take Salgado (26-2-1, 16 KO) apart this evening, and that's no easy task.

Mendez floored Salgado in the first round, then whacked the Mexican titlist around in the second and third. Though Mendez could have thrown more punches, it didn't wind up matter, and his performance left little to be desired. In the fourth round, with Salgado trying to push his way back into the fight, Mendez landed a brutal left hook for a one-punch knockout. Salgado just didn't have it tonight, and Mendez did.

There's no telling what's next for Mendez, but a fight with Japan's Takashi Uchiyama (the WBA titlist) would be excellent, a pair of guys who can bang and come to fight, and right now look to be the best out there at 130 pounds.
