Ariel Sexton advanced into the semifinals of the ONE Lightweight World Grand Prix after a slick submission finish over Amir Khan at ONE: CALL TO GREATNESS. The American-Costa Rican grappling specialist was relentless in his pursuit to take the action to the ground. “Tarzan” began to capitalize on a slowing Amir Khan in the second gaining the mount just seconds before the end of the second round. Though he ran out of time then, Sexton regained control once again in early in the third round before fastening a deep rear-naked choke to force the tap from Khan.
