Formula: 100 × (SO − BB) ÷ BF

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.
