Jack Leathersich: Leathersich had a pretty impressive 9 game audition in 2011. The 5th round pick managed 12.2 IP with only 6 Hits, 3 Walks and 26 K’s! He followed up that impossible feat with 12 games and 24.0 innings at Savannah in 2012. Through A ball he’d managed 63 K’s in 36 innings (a 15.49 K/9). Then he got promoted to Port St. Lucie and he showed he was human. His ERA in A+ ball was 4.12 and H/9 and BB/9 both rose. His K-Rate remained spectacular: 14.2 K/9 (76 K’s in 48.0 IP).
Scouting: At 5’11”, Leathersich is not a dominating looking player. He’s not really built like a modern pitcher at all.
Fastball: A pitcher who gets a K/9 that high must have a killer fastball, right? WRONG! Leathersich lives at 90-91 MPH and touches 92. Or a lefty that isn’t bad but Aroldis Chapman isn’t worried about someone having more gas than him. Leathersich get’s those K’s because he’s got a deceptive delivery which makes that 90-ish fastball look a lot harder to hit than
