Edwin Palomares' pressure was just too much for Carlos Ornelas on Saturday night in Mexico City.

The determined Mexican featherweight wore down Ornelas, dropped him with a body shot in the fifth round and stopped him in that round. Mexico's Ornales never figured out how to fend off Palomares in the third fight ESPN televised as part of the Emanuel Navarrete-Uriel Lopez undercard from TV Azteca's Studios.

The 24-year-old Palomares improved to 13-3-1 and recorded his fourth knockout. The 25-year-old Ornelas (25-3, 14 KOs) lost by technical knockout for the third time as a pro.
