BB/9: Walks allowed per nine innings pitched, including intentional walks.

Understanding Walks per 9 Innings

Walks allowed per nine innings pitched, including intentional walks.

Formula: 27 × BB ÷ outs recorded

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.
