Baseball is a game of numbers, and one of the most important statistics used to evaluate pitchers is WHIP.
WHIP stands for Walks plus Hits per Inning Pitched, and it provides valuable insights into a pitcher’s ability to prevent baserunners.
Here we’ll look into the details of WHIP, its calculation, significance, and how it can be used to assess a pitcher’s performance.
Understanding WHIP
WHIP is a measure of a pitcher’s effectiveness in preventing opposing batters from reaching base.
It takes into account both walks and hits allowed by the pitcher and calculates the average number of baserunners they allow per inning pitched.
The lower the WHIP, the better the pitcher is at keeping runners off base.
Calculating WHIP
The formula to calculate WHIP is relatively straightforward:
WHIP = (Walks + Hits) / Innings Pitched
For example, if a pitcher has allowed 50 hits and 20 walks in 100 innings pitched, their WHIP would be:
WHIP = (50 + 20) / 100 = 0.70
Therefore, their WHIP would be 0.70.
Significance of WHIP
WHIP is a valuable statistic because it provides a comprehensive measure of a pitcher’s ability to limit baserunners.
By considering both walks and hits, WHIP captures the full picture of a pitcher’s performance in terms of preventing opposing teams from scoring runs.
Since WHIP is calculated per inning pitched, it allows for easy comparison between pitchers regardless of the number of innings they have pitched.
This makes it a useful tool for evaluating both starters and relievers.
WHIP in Action
To better understand the significance of WHIP, let’s take a look at some examples and case studies:
Example 1: Clayton Kershaw
Clayton Kershaw, a left-handed pitcher for the Los Angeles Dodgers, is widely regarded as one of the best pitchers of his generation.
His career WHIP is an impressive 1.00, which demonstrates his ability to limit baserunners.
In 2014, Kershaw had a historic season with a WHIP of 0.86.
This means that, on average, he allowed less than one baserunner per inning pitched.
His exceptional WHIP was a contributing factor to his dominant performance that year, which earned him the National League Cy Young Award.
Example 2: Mariano Rivera
Mariano Rivera, a legendary relief pitcher for the New York Yankees, is widely considered one of the greatest closers in baseball history.
His career WHIP of 1.00 is a testament to his ability to shut down opposing teams and secure victories for his team.
Rivera’s ability to limit baserunners was critical in his success as a closer.
His low WHIP allowed him to navigate high-pressure situations and prevent opposing teams from mounting comebacks.
Using WHIP for Evaluation
WHIP is a valuable tool for evaluating pitchers and comparing their performances.
Here are some ways in which WHIP can be used for evaluation:
1. Comparing Pitchers
WHIP allows for easy comparison between pitchers, regardless of the number of innings they have pitched.
By comparing their WHIPs, we can assess which pitcher is more effective at preventing baserunners and limiting scoring opportunities for the opposing team.
2. Assessing Consistency
WHIP can also be used to assess a pitcher’s consistency over time.
By tracking a pitcher’s WHIP over multiple seasons, we can identify trends and determine if their performance is improving or declining.
3. Identifying Potential Breakout Performances
A sudden decrease in a pitcher’s WHIP can indicate a breakout performance.
If a pitcher’s WHIP significantly improves compared to previous seasons, it may suggest that they have made adjustments to their pitching style or have developed new pitches that are more effective at limiting baserunners.

FAQs: What Is WHIP in Baseball?
1. What does WHIP stand for?
WHIP stands for Walks plus Hits per Inning Pitched.
2. How is WHIP calculated?
WHIP is calculated by dividing the sum of walks and hits allowed by a pitcher by the number of innings pitched.
3. What is a good WHIP for a pitcher?
A good WHIP for a pitcher is typically below 1.00. The lower the WHIP, the better the pitcher is at preventing baserunners.
4. Can WHIP be negative?
No, WHIP cannot be negative. It is always a positive value.
5. Is WHIP more important than ERA?
WHIP and ERA are both important statistics for evaluating pitchers, but they provide different insights.
WHIP focuses on preventing baserunners, while ERA measures a pitcher’s ability to prevent runs from scoring.
Both statistics should be considered together for a comprehensive evaluation.
6. Can a pitcher have a high WHIP and still be successful?
While a low WHIP is generally preferred, a pitcher can still be successful with a high WHIP if they have other strengths, such as a high strikeout rate or the ability to induce ground balls.
However, a high WHIP often indicates that the pitcher is allowing too many baserunners, which can increase the likelihood of runs being scored against them.
7. Does WHIP account for errors made by fielders?
No, WHIP does not account for errors made by fielders.
It only considers walks and hits allowed by the pitcher.
8. Can a pitcher have a WHIP below 1.00?
Yes, a pitcher can have a WHIP below 1.00.
In fact, many elite pitchers have achieved WHIPs below this threshold.
9. Is WHIP the only statistic used to evaluate pitchers?
No, WHIP is just one of many statistics used to evaluate pitchers.
Other important statistics include ERA, strikeouts per nine innings (K/9), and walks per nine innings (BB/9).
10. Can a pitcher’s WHIP change over the course of a game?
Yes, a pitcher’s WHIP can change over the course of a game as they allow walks or hits.
However, WHIP is typically calculated based on the entire season or a specific period of time, rather than on a game-by-game basis.
11. Is WHIP more important for starters or relievers?
WHIP is important for both starters and relievers. It allows for easy comparison between pitchers regardless of their role.
However, WHIP may carry more weight for relievers since they often pitch in high-pressure situations where preventing baserunners is crucial.
12. Can WHIP be used to predict future performance?
WHIP can provide insights into a pitcher’s ability to prevent baserunners, but it should not be solely relied upon to predict future performance.
Other factors, such as a pitcher’s repertoire, mechanics, and overall skill level, should also be considered.
13. Are there any limitations to using WHIP?
While WHIP is a valuable statistic, it does have some limitations.
For example, it does not account for the quality of hits allowed by a pitcher or the sequencing of those hits.
Additionally, WHIP does not consider other factors that can impact a pitcher’s performance, such as defensive abilities or ballpark factors.
14. Can a pitcher have a low WHIP but a high ERA?
Yes, it is possible for a pitcher to have a low WHIP but a high ERA.
This can occur if the pitcher allows hits and walks but manages to limit the damage by inducing double plays or getting strikeouts when runners are on base.
15. How does WHIP compare across different eras?
WHIP can vary across different eras due to changes in the game, such as rule changes, offensive strategies, and advancements in player development.
It is important to consider the context of the era when comparing WHIP across different time periods.
Summary
WHIP, or Walks plus Hits per Inning Pitched, is a crucial statistic in baseball that measures a pitcher’s ability to prevent baserunners.
It provides valuable insights into a pitcher’s effectiveness and can be used to compare performances, assess consistency, and identify breakout performances.
While WHIP is just one of many statistics used to evaluate pitchers, it offers a comprehensive measure of a pitcher’s ability to limit scoring opportunities for the opposing team.
By understanding and utilizing WHIP, baseball enthusiasts can gain a deeper appreciation for the art of pitching and the impact it has on the game.
