We tend to focus on hitters over pitchers when discussing prospects likely to positively impact a fantasy baseball roster, because hitters are less prone to wild variance and workload restrictions and generally cannot hurt a fantasy team with awful statistics as much. Pitchers can do major damage. Just look at Texas Rangers RHP Jack Leiter (16.39 ERA in three starts) this season, or Los Angeles Dodgers RHP Gavin Stone (9.00 ERA in 31 IP) last year. Pirates RHP Paul Skenes, clearly, is different.
The San Diego Padres, after losing RHPs Yu Darvish and Joe Musgrove to the injured list recently, promoted RHP Adam Mazur for Tuesday's start against the Angels. The 2022 second-round pick made six starts at Double-A San Antonio, posting a 1.95 ERA and 0.87 WHIP. That's good! He made four starts at Triple-A El Paso, delivering an inconvenient 7.11 ERA. With a plus slider and changeup complimenting his mid-90s fastball, Mazur may thrive Tuesday and stick in San Diego's rotation for years. Or he may be back in the minors soon. Do you feel lucky, fantasy managers?
