What Is WHIP in Baseball?

WHIP stands for walks plus hits per inning pitched. It measures how many baserunners a pitcher allows per inning, calculated as walks plus hits divided by innings pitched. Lower is better. A WHIP under 1.00 is elite, around 1.10 to 1.25 is very good, and most seasons the league average sits near 1.25 to 1.35.

How WHIP is calculated

WHIP is walks plus hits, divided by innings pitched. If a pitcher allows 1 walk and 5 hits over 7 innings, that is 6 baserunners over 7 innings, a WHIP of about 0.86. It answers one simple question: how many runners does this pitcher put on base per inning? Hit batters and runners who reach on errors are not counted, only walks and hits, so WHIP is a clean read on the baserunners a pitcher is directly responsible for.

What counts as a good WHIP

Lower is better, because fewer baserunners means fewer chances to score. The rough scale:

Why WHIP matters for betting

WHIP is one of the most useful pitcher ratios because it tracks traffic on the bases, which drives runs, and it is steadier than ERA. ERA can be wrecked by one bad inning or rescued by good defense, while WHIP reflects the pitcher's underlying ability to keep runners off. A low WHIP supports the under on a pitcher's hits-allowed and earned-runs props, and it often travels with strikeout upside: a pitcher who does not walk batters and does not give up hits is usually missing bats too. Read it next to strikeout rate rather than on its own.

How to use it with strikeout props

A low-WHIP arm tends to work deeper into games because he is efficient and not laboring through traffic, and more innings means more chances to pile up strikeouts. Pair a low WHIP with a high strikeout rate against a whiff-prone lineup and you have the profile behind a strong strikeout-prop over. A high WHIP, by contrast, can mean early exits that cap the strikeout ceiling no matter the matchup.

Frequently asked questions

What is a good WHIP in baseball?
Under 1.00 is elite, 1.10 to 1.25 is very good, and roughly 1.25 to 1.35 is around league average in most seasons. Anything above 1.50 signals a pitcher allowing far too many baserunners.
How is WHIP calculated?
Walks plus hits, divided by innings pitched. It counts only walks and hits, not hit batters or reaches on error, so it measures the baserunners a pitcher is directly responsible for.
Is WHIP better than ERA?
They measure different things. ERA tracks runs allowed and can be skewed by defense and one bad inning, while WHIP tracks baserunners per inning and is steadier. Many bettors read WHIP as the more stable of the two.
What is the difference between WHIP and K%?
WHIP measures baserunners allowed per inning. K% measures the share of plate appearances that end in a strikeout. A strong pitcher usually posts a low WHIP and a high K% together.
