What whiff rate measures
Whiff rate is the percentage of swings that a pitcher generates without contact (swinging strikes divided by total swings, not total pitches). It isolates a pitcher's pure "miss-bats" ability independent of whether hitters chase out of the zone. League average hovers around 24-25%; elite swing-and-miss pitchers clear 30%, and the unicorns exceed 35%. Pitchers need at least 100 batters faced.
Why whiff rate matters
Whiff rate is highly predictive of strikeout rate and tends to stabilize early in a season. Pitchers with elite whiff rates but modest strikeout totals are often called-ball-dependent arms about to break out once command catches up to their stuff.
