Bill Williams built a career as a starting pitcher and John Barthold as a reliever — different jobs with different demands — but on the metrics that apply to both, a comparison is still worth making. John Barthold posted a career ERA of 5.06 against Bill Williams's 5.06, with WHIP of 1.875 and 1.313 respectively.
