Fernando Valenzuela vs. Frank Williams — Career Comparison

Fernando Valenzuela built a career as a starting pitcher and Frank Williams as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. Frank Williams led in home run suppression (HR9+ 185 vs 110), run prevention (ERA+ 119 vs 95), and strikeout rate (K%+ 96 vs 79). Role difference aside, Frank Williams holds a clear edge on every meaningful shared measure.
