New Slider Propels Adonis Medina

Phillies Prospect Report

Last season, when righthander Adonis Medina made his final start for short-season Williamsport, he incorporated a new slider. The pitch, hatched by pitching coach Hector Berrios, was an attempt to combat Medina’s low strikeout rate. The righthander struck out seven batters, which equaled his total from his previous four starts combined.

Medina played with the slider all winter while in the Dominican Republic. His results this season at low Class A Lakewood are proof of its importance.


“Now, I feel like I have a couple of pitches to strike out hitters,” Medina said through a coach’s translation. “I have the slider and the fastball. Before, I depended on my fastball too much.”
