About this calculator
Overview
ERA (Earned Run Average) and WHIP (Walks plus Hits per Inning Pitched) are the two primary metrics used to evaluate a pitcher's effectiveness and control.
💡
Pro Tips
A 'Quality Start' is 6+ innings with 3 or fewer earned runs.
WHIP specifically measures a pitcher's ability to keep runners off base.
ERA is calculated based on 9 innings of work.
League average ERA varies by season but usually sits between 4.00 and 4.50.
