Watch: Raul Rosas Jr. gets back on track with violent finish at Noche UFC

Raul Rosas Jr. is back in the win column in a big way.

The 18-year-old bantamweight phenom wasted no time in his Noche UFC bout Saturday night in Las Vegas, steamrolling Terrence Mitchell in 54 seconds.

Rosas is back on track after suffering his first career loss against Christian Rodriguez at UFC 287 in April.

The Mexican-American, who signed with the UFC last year after an appearance on Dana White's Contender Series, is the youngest fighter on the roster and a highly touted prospect. Rosas is now 7-1 as a pro and 2-1 in the UFC.
