Daniel Cabrera vs. John Rocker — Career Comparison

Daniel Cabrera built a career as a starting pitcher and John Rocker as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. John Rocker led in run prevention (ERA+ 159 vs 92), strikeout rate (K%+ 160 vs 111), and skill-based run prevention (DICE+ 127 vs 95).
