Jack Armstrong vs. Pedro Baez — Career Comparison

Jack Armstrong built a career as a starting pitcher and Pedro Baez as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. Pedro Baez led in run prevention (ERA+ 136 vs 89), home run suppression (HR9+ 129 vs 85), and skill-based run prevention (DICE+ 123 vs 89). Role difference aside, Pedro Baez holds a clear edge on every meaningful shared measure.
