Jack Armstrong vs. David Lee — Career Comparison

Jack Armstrong built a career as a starting pitcher and David Lee as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. David Lee led in home run suppression (HR9+ 122 vs 85), run prevention (ERA+ 117 vs 89), and skill-based run prevention (DICE+ 92 vs 89). Jack Armstrong held the edge in walk avoidance (BB%+ 91 vs 78). Keeping the role difference in mind, the edge still goes to David Lee.
