It was a shot so quick that if you blinked you would’ve missed it. But a short left hand by Mario Pinto may have been the key to earning a UFC contract.

At Dana White’s Contender Series 75 on Tuesday, Pinto (9-0) floored and finished Lucas Camacho (6-1) with punches at 1:43 of Round 1 at the UFC Apex in Las Vegas.

Pinto was the Levels Fight League heavyweight champion prior to Tuesday’s bout. Six of his nine professional victories have come by knockout with five of them knockouts.

Camacho loses for the first time as a professional. He had back-to-back wins under the LFA banner entering Tuesday’s bout.
