HR/9: Home runs allowed per nine innings pitched.

Understanding Home Runs per 9 Innings

Home runs allowed per nine innings pitched.

Formula: 27 × HR ÷ 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.
