Formula: WHIP = (Walks + Hits Allowed) / Innings Pitched
Worked example — WHIP: 0.952 (Elite) — Fewer than 1 baserunner per inning
Formula
WHIP = (Walks + Hits Allowed) / Innings Pitched
WHIP measures the average number of baserunners a pitcher allows per inning through walks and hits. Lower values indicate better pitcher performance. It does not include hit-by-pitches or errors.
Worked Examples
Example 1: Ace Starter Season
Problem:A starting pitcher has 45 walks, 155 hits allowed over 210 innings pitched. Calculate their WHIP.
Solution:WHIP = (Walks + Hits) / Innings Pitched WHIP = (45 + 155) / 210 WHIP = 200 / 210 WHIP = 0.952 Baserunners per 9 innings = 0.952 x 9 = 8.57
Result:WHIP: 0.952 (Elite) — Fewer than 1 baserunner per inning
Example 2: League Average Pitcher
Problem:A pitcher has 65 walks and 195 hits allowed in 180 innings. Calculate their WHIP.
Solution:WHIP = (Walks + Hits) / Innings Pitched WHIP = (65 + 195) / 180 WHIP = 260 / 180 WHIP = 1.444 Baserunners per 9 innings = 1.444 x 9 = 13.0
Result:WHIP: 1.444 (Poor) — About 13 baserunners per full game
Frequently Asked Questions
What is WHIP in baseball?
WHIP stands for Walks plus Hits per Inning Pitched, and it is one of the most commonly used pitching statistics in baseball. It measures the average number of baserunners a pitcher allows per inning through walks and hits combined. A lower WHIP indicates a more effective pitcher who limits opposing batters from reaching base. The statistic was invented by writer Daniel Okrent in 1979, originally calling it Innings Pitched Ratio. WHIP has become a standard evaluation metric in both traditional scouting and modern sabermetric analysis, appearing on every major baseball statistics website and broadcast.
What is a good WHIP for a pitcher?
WHIP values are generally evaluated on a sliding scale. An elite pitcher will have a WHIP at or below 1.00, meaning they allow fewer than one baserunner per inning on average. A WHIP between 1.00 and 1.10 is considered excellent and typical of ace-caliber pitchers. Values between 1.10 and 1.20 are above average, while the league average typically hovers around 1.25 to 1.30. A WHIP above 1.40 is generally considered poor for a starting pitcher. Relief pitchers often have lower WHIPs than starters because they pitch fewer innings and can maintain higher intensity. Historical greats like Pedro Martinez achieved season WHIPs below 0.75.
How is WHIP calculated and what does the formula mean?
WHIP is calculated using the simple formula: WHIP equals walks plus hits divided by innings pitched. For example, if a pitcher allows 60 walks and 170 hits over 200 innings, their WHIP would be (60 plus 170) divided by 200, equaling 1.150. The formula captures the two primary ways batters reach base against a pitcher through their own doing, which are getting a hit or receiving a base on balls. Hit batsmen, errors, and fielders choices are not included in the WHIP calculation. The stat is straightforward to compute and provides an intuitive measure of how many baserunners a pitcher surrenders per inning of work.
What are the limitations of WHIP as a pitching statistic?
While WHIP is useful, it has several notable limitations. It treats all hits equally, meaning a single counts the same as a home run, even though a home run is far more damaging. It does not account for hit batters, which also put runners on base. WHIP ignores the sequencing of events, so a pitcher who scatters hits across multiple innings looks the same as one who allows them in clusters. It does not reflect the quality of defense behind the pitcher or the ballpark environment. Additionally, WHIP does not distinguish between different types of walks such as intentional walks. Modern analysts often supplement WHIP with stats like FIP and xFIP for deeper evaluation.
How does WHIP compare to ERA for evaluating pitchers?
WHIP and ERA measure different aspects of pitching performance and are most valuable when used together. ERA, or Earned Run Average, measures the number of earned runs a pitcher allows per nine innings and directly reflects scoring. WHIP measures baserunner traffic regardless of whether those runners ultimately score. A pitcher can have a low WHIP but a high ERA if the few baserunners they allow tend to score, perhaps due to poor timing or home runs. Conversely, a pitcher might have a higher WHIP but lower ERA if they consistently strand runners. WHIP is often considered a better predictor of future performance because it is less subject to luck and sequencing effects than ERA.
