Pittsburgh Pirates Prospect Stock Watch: LHP Jackson Wolf

Repotier

Wolf is a soft-tossing lefty. In his lone MLB game, Wolf’s hardest-thrown pitch was 90.8 MPH. He typically sits 88-90 MPH, but his fastball plays above its metrics. Wolf has a sidearm motion that can throw batters off. He also can throw his four-seamer with sinking action, which was a trait that he showed off in his MLB debut.

His four-seam fastball is far from the only pitch in his repertoire. His best breaking pitch is his slider, a pitch with sweeping action (but not considered a sweeper). He also throws a curveball, which has enough distinctive qualities to make it a second offering. Both of his breaking pitches are considered to have above average potential.

Wolf has attempted to improve his change-up, his one off-speed offering. While it has the potential to be an average offering, most pin it as a fourth, get-me-over kind of pitch. Wolf used this pitch solely against right-handed batters in his debut, so maybe he feels most comfortable when using it against opposite-handed opponents.
