WHIP Explained: Walks Plus Hits Per Inning Pitched
Understand WHIP in baseball, how it measures baserunner traffic, and how to pair it with ERA when evaluating pitchers.
What WHIP measures
WHIP is walks plus hits divided by innings pitched. It estimates how many baserunners a pitcher allows through the two most common free passes onto the bases: hits and walks.
Because scoring usually starts with traffic, WHIP is a quick hygiene check on a pitcher’s ability to keep innings clean even before looking at run prevention.
Reading WHIP with ERA
A low WHIP with a high ERA can signal sequencing misfortune or home-run clustering. A high WHIP with a low ERA can signal strand-rate luck that may not hold. Together they tell a clearer story than either number alone.
On Ballrecord, scan pitching leaders for ERA first, then inspect individual pitcher pages for hits, walks, and innings that feed WHIP-style evaluation.
Frequently asked questions
- Does WHIP include hit batters?
- Classic WHIP uses walks and hits only. Hit batters matter for run prevention but are outside the standard WHIP formula.
- Is a WHIP under 1.00 elite?
- Yes in modern MLB. Sustaining a sub-1.00 WHIP over a qualifying workload is rare and usually belongs to ace-level seasons.
