Hector Silvestre LHP Evaluated 6/4 & 4/19/17
Fastball (40/45) Slider (40/40) Changeup (40/45) Command (50/50)
International free agent signee in January 2011 by the Washington Nationals; Born in December 1992, Silvestre will spend this entire season at 24 y/o. Silvestre is a well-built and wiry strong 6-3 180lbs with little projection remaining. He utilizes a relatively simple, 1-step and rock delivery with few moving parts and he repeats his mechanics fairly well both from windup and stretch. Silvestre throws from a medium 3/4s arm slot and pitches from the extreme third base side of the rubber. There is some deception in the delivery, especially for lefties, as he hides ball well with his body through his pitching motion.
3-pitch repertoire – Fastball (89-91mph, T92) has natural cutting action in toward righties, especially at lower velocities – Silvestre locates the fastball well low in the zone, but struggles to command above the belt; pitch generates swings-and-misses. His slider (79mph-83mph) is rather inconsistent both in shape and quality, some flash late bite into the strike zone and others are rather loopy. The changeup (82-84mph) replicates arm speed well and shows quality arm-side fade, but he struggles to throw it for strikes as it tends to drift outside the zone.
Silvestre is a well-built and polished left-handed pitcher with three decent but inconsistent offerings. He is somewhat old for the High-A level and his lack of an above-average future pitch limits his ceiling. Silvestre is a crafty lefty who competes and knows how to pitch. Unless his offspeed stuff improves, Silvestre possesses the ceiling as a quality Triple-A starter who unfortunately stagnates in the upper minors.
