J. A. Happ vs. Phil Maton — Career Comparison

J. A. Happ built a career as a starting pitcher and Phil Maton as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. Phil Maton led in walk avoidance (BB%+ 114 vs 95), home run suppression (HR9+ 88 vs 80), and run prevention (ERA+ 103 vs 96). Role difference aside, Phil Maton holds a clear edge on every meaningful shared measure.
