WHIP (Walks plus Hits per Inning Pitched) measures how many baserunners a pitcher allows per inning, adding up hits and walks. It’s a direct way to see how often a pitcher puts men on base: the lower, the more dominant.
How is it calculated?
WHIP = (Walks + Hits) ÷ Innings pitched
A WHIP of 1.00 means the pitcher allows, on average, one baserunner per inning.
What is a good WHIP?
| WHIP | Level |
|---|---|
| Under 1.00 | Elite |
| 1.00 – 1.15 | Excellent |
| 1.15 – 1.30 | Good |
| Over 1.40 | Below average |
Examples with players
- Pedro Martínez posted a 0.74 WHIP in 2000, the best single season in modern history.

Why it matters
WHIP complements ERA: a pitcher with a low WHIP controls the game because he barely allows anyone on base, which reduces scoring threats.
