Lefty Jackson Wolf

One of the Pirates’ newest pitching prospects, Jackson Wolf, also throws under 90. Wolf is a left-hander who had a 4.00 ERA, 3.84 FIP, and 1.09 WHIP on the year. The lefty has struck out 29.2% of opponents with a 1.15 HR/9 rate and a strong 6.6% walk rate. Jackson has already made his debut despite not pitching a game at Triple-A yet.

In that one game, Wolf averaged just 88.9 MPH. His fastball, however, isn’t his only pitch. He also tosses a slider, curveball, and changeup. Wolf is a sidearmer with above-average command, so despite lacking seriously powerful stuff, he can get batters out. Wolf is one of the organization's better pitching prospects and could potentially be in the starting rotation by the end of the season.
