Next up is Velasquez taking on O'Brien with Mario Yamasaki serving as referee. The two men exchange punches early as O'Brien goes for a takedown put exposes his back and Velasquez promptly takes advantage. O'Brien rolls to his back and gives up side control to Velasquez who secures the crucifix position and lands a string of unprotected punches. Yamasaki is allowing the action to go on but Velasquez is absolutely relentless with strikes while maintaining the crucifix which forces Yamasaki to step in and halt the bout. Impressive showing by Velasquez who wins via TKO at the 2:02 mark of the first round.
