Understanding Range Factor/9

Putouts plus assists per nine defensive innings. Compare players at similar positions; this is not a tracking-based defensive measure.

Formula: 27 × (PO + A) ÷ defensive outs

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.
