What is Walks and Hits per Inning Pitched (WHIP)?

WHIP is a baseball pitching metric that shows walks and hits allowed for each inning pitched. It is an alternative to the more popular Earned Run Average. Unlike ERA, WHIP shows pitcher performance regardless of fielding performance as it does not include errors and unearned runs.
A lower WHIP number is considered better, as it means that the pitcher allows fewer batters on base for each inning pitched.

How to calculate WHIP

In Baseball, on Walks and Hits to Inning Pitched is calculated as:
WHIP = (Walks + Hits) / (Innings Pitched + (Outs (Partial Innings) Pitched / 3))


If a pitcher has allowed 190 hits and 43 walks over 202 innings and 1 out, then:
WHIP = (190 + 43) / (202 + (1/3))
WHIP = 233 / 202.333333
WHIP = 1.152
On an average inning, this pitcher allows a combined 1.152 walks and hits.
