Round 1 - Melancon lands early, but it's Gastelum who powers in after 45 seconds for a double-leg takedown. Melancon works his way back to the feet, though, and lands a shot to the body. As Melancon comes forward again, Gastelum again lands a takedown, but they pop right back up. High kick lands for him, and then three punches after that. Melancon tries to go to the head, but Gastelum kicks to the body, then lands some big combos. He drops Melancon quickly with a left uppercut, then very quickly moves around and takes his back. He locks up a rear-naked choke and rolls it over. It's deep, and Melancon has to tap.
Result: Kelvin Gastelum def. Brian Melancon via submission (rear-naked choke) - Round 1, 2:26
