The Padres are calling up pitcher Jackson Wolf for tomorrow’s game in Detroit, manager Bob Melvin tells AJ Cassavell of MLB.com (Twitter link). The club hasn’t decided whether Wolf will start the contest or work in relief. They’ll need to formally select him onto the 40-man roster tomorrow.
Wolf, 24, was a fourth-round selection out of West Virginia in the 2021 draft. The 6’7″ lefty split his first full professional season between High-A and Double-A. He has spent 2023 with Double-A San Antonio, starting all 17 appearances. He has excelled through 85 innings, pitching to a 3.39 ERA. Wolf is striking hitters out at an elite 31.3% rate and has only walked 6% of opposing batters.
That was a strong enough showing the Friars will skip him past the hitter-friendly Pacific Coast League entirely. He makes the jump straight from Double-A to at least get the opportunity for his major league debut. San Diego has been without Michael Wacha for nearly three weeks due to shoulder inflammation, leaving a rotation vacancy.
Earlier this month, Eric Longenhagen of FanGraphs ranked Wolf the #11 prospect in a relatively thin San Diego farm system. While his fastball only sits in the upper 80s, Longenhagen credits him with a plus slider and suggests his lower arm slot presents a particularly challenging look for left-handed hitters.
San Diego’s 40-man roster is full. They’ll likely wind up designating someone for assignment tomorrow to create space.
