Del Rosario shined on Friday’s MMA beating his opponent in emphatic fashion. Del Rosario (10-0) took less than four minutes to dispatch Lolohea Mahe (4-2) with a technical knockout on Friday in the main event of the Strikeforce Challengers event in Everett, Wash. Del Rosario rocked Mahe with knees in the clinch and finished him with punches against the fence to provoke the referee stoppage.

It was Del Rosario’s fifth Showtime bout on a smaller show, including two fights for EliteXC’s developmental circuit before joining Strikeforce. Going into the bout, Strikeforce CEO Scott Coker characterized the Mahe fight as a “graduation opportunity” for Del Rosario.
