MARIO’S LATEST: Enerio Del Rosario is latest Mario Soto protege.

“He’s one of my guys,” Soto said.

Del Rosario, a 23-year-old right-hander, went a combined 3-1 with a 1.72 ERA last year. He started in Single-A Sarasota went to Double-A Carolina and then to Triple-A Louisville.

“He used to be an over-the-top guy,” Soto said. “Now, he throws sidearm. His ball has so much movement that all they do is hit groundballs to the infield.”
