Understanding Knuckle curve: Average Extension

How far toward home plate the pitcher releases the ball, measured in feet from the pitching rubber. Only pitches with this measurement are included. Uses pitches recorded as knuckle curve.

Formula: Sum of recorded extensions ÷ pitches with extension measurements

Read rates alongside playing time. A small sample can produce an extreme result, and a missing value is different from zero.

Season rankings use regular-season records. A player has one combined row across teams; the team label identifies the associated team, not a separate team stint.
