The Significance of WHIP in Baseball Analytics

Introduction to WHIP in Baseball

Baseball is a sport that is known and loved all over the world. The sport has been around for more than a century, and over the years, the game has developed in various ways.

One of the developments that have changed the way baseball is played is the introduction of WHIP.

WHIP, or Walks plus Hits divided by Inning Pitched, is a statistic that was created by fantasy baseball enthusiast David Okrent in the 1980s.

Okrent came up with the idea of WHIP while playing rotisserie fantasy baseball, a game that assigns point values for individual player statistics. The WHIP statistic has since become an integral part of baseball analytics and is used to evaluate a pitcher’s effectiveness on the mound.

In this article, we will explore the origin of WHIP in baseball, explain the formula used to calculate it, and highlight its significance in evaluating pitcher performance.

Origin and Calculating WHIP

Creation of WHIP by David Okrent

David Okrent was one of the founding fathers of rotisserie baseball, now known as fantasy baseball. He initially created a league with friends in the early 1980s, where each owner drafted their team of players and tracked the player’s statistical performance throughout the season, earning points for specific statistical achievements.

As Okrent became more involved in the decision-making process of the league, he realized that the statistics that were currently being used to evaluate pitcher performance did not reflect their effectiveness on the mound truly. ERA, or Earned Run Average, was only taking into account the number of earned runs a pitcher was giving up but wasn’t accounting for the number of baserunners allowed.

This led Okrent to create the WHIP statistic, which would factor in both walks and hits allowed per inning. The original name for WHIP was “IPRAT,” short for “Innings Pitched Ratio.” However, the name did not catch on, and WHIP was born.

Formula for calculating WHIP

The WHIP formula is relatively simple, as it only takes into account three variables: walks, hits, and innings pitched. The formula is as follows:

WHIP = (Walks + Hits) / Innings Pitched

To calculate a pitcher’s WHIP for a game, all you need to do is find the number of walks and hits they allowed in that game, along with the number of innings pitched.

Once you have those values, you can plug them into the equation and get the pitcher’s WHIP for that game. For example, if a pitcher allowed three hits and two walks in a seven-inning outing, their WHIP for that game would be 0.714, as calculated below:

WHIP = (3 hits + 2 walks) / 7 innings pitched

WHIP = 0.714

It’s important to note that WHIP is calculated based on innings pitched, not games played.

This means that if a pitcher leaves a game early due to injury or is removed from the game for performance reasons, the innings they did pitch will still be counted towards their WHIP.

Significance of WHIP

WHIP is an essential statistic in evaluating a pitcher’s effectiveness on the mound. It’s a measure of how many baserunners a pitcher allows per inning, giving us insight into how difficult it is for batters to get on base against that pitcher.

A lower WHIP indicates that a pitcher is more effective on the mound since it means that they are not allowing as many baserunners as a pitcher with a higher WHIP. WHIP can also be used to predict a pitcher’s future success.

If a pitcher has a low WHIP, it’s likely that they will continue to perform at a high level since they are not allowing many baserunners. However, if a pitcher’s WHIP is high, it’s possible that they will struggle in future outings since they are allowing too many baserunners on average.

Conclusion

In conclusion, WHIP is a critical statistic in evaluating pitcher effectiveness on the mound. It is a measure of how many baserunners a pitcher allows per inning, and a lower WHIP indicates that a pitcher is more effective on the mound.

The formula for calculating WHIP is straightforward, as it only takes into account the number of walks, hits, and innings pitched. Okrent’s creation of WHIP has changed the way baseball is played and has become an integral part of baseball analytics.

Evaluating WHIP

Now that we have a basic understanding of what WHIP is and how it’s calculated, let’s explore what constitutes a good and excellent WHIP value, as well as the average and poor WHIP values in Major League Baseball (MLB).

Good and Excellent WHIP Values

In general, a WHIP below 1.1 is considered good, and a WHIP below 1 is considered excellent. It’s important to note that WHIP values can vary based on the era of baseball that a pitcher played in.

The average WHIP in MLB has decreased in recent years due to changes in player behavior and strategy, making it more challenging for pitchers to succeed. Pitchers in today’s game, who manage to post a WHIP below 1.00, are widely considered to be elite.

For example, in 2019, Houston Astros pitcher Justin Verlander led the league in WHIP with a remarkable 0.80 WHIP.

Average WHIP in MLB and Poor WHIP Value

The average WHIP in MLB varies every year. However, it generally hovers around 1.30.

This is because the league average keeps changing every season with the changing trends in baseball. While a WHIP above 1.5 is generally considered a poor value, it’s important to consider other factors.

For instance, a high WHIP might not necessarily mean that a pitcher is not effective. In some cases, pitchers may have a high WHIP but still manage to pitch well in high leverage scenarios.

Looking at extreme cases, consider the 2019 MLB season, where the highest WHIP value was 2.342, which belonged to Seattle Mariners pitcher Yusei Kikuchi. He performed below average and struggled on the mound, which led to his high WHIP.

Caveats of WHIP

While WHIP is a valuable statistic to evaluate pitcher performance, it’s essential to consider some of its limitations.

Limitations of WHIP in Measuring Performance

WHIP is a measure of how often a pitcher gives up baserunners, but it doesn’t account for other factors such as hit-by-pitches, errors, and fielder’s choice. It also doesn’t account for the variables that might not be purely the pitcher’s performing, including the quality of the defense behind the pitcher.

For example, a pitcher may give up a ground ball that deflects off the glove of an infielder for a hit. This situation will negatively affect the pitcher’s WHIP, even though it was not his fault.

Thus, using WHIP alone to evaluate a pitcher’s performance doesn’t provide the entire picture.

Arguments for and against WHIP as a Measure

There are arguments for and against using WHIP as a measure of pitching performance. Some argue that WHIP is a comprehensive measure of pitching effectiveness since it includes basic metrics like hits and walks allowed.

They believe that a good WHIP is an effective tool for identifying good pitchers who give their teams the best chance to win. However, others argue that WHIP has its limitations.

They believe that measures like xFIP (expected fielding independent pitching) better account for elements outside of a pitcher’s control. Another argument against using WHIP is that it does not account for the type of contact a pitcher allows, such as fly balls, ground balls, line drives, etc.

In some cases, allowing lots of ground balls or inducing weak contact can be just as effective as preventing baserunners.

Final Thoughts

While WHIP is an essential statistic in evaluating a pitcher’s effectiveness, it’s not without its caveats. Considering other factors and exploring alternative metrics can provide a more complete picture of a pitcher’s performance, although WHIP still retains its role as one of the most important performance indicators used in evaluating pitchers in modern-day baseball.

Associates of WHIP

We have discussed how WHIP is calculated and its significance in evaluating pitcher performance. In this section, we will explore the relationship between WHIP and ERA, as well as compare WHIP to Baserunners Per Nine Innings (MB/9).

Relationship between WHIP and ERA

ERA, or Earned Run Average, is another vital statistic used to evaluate a pitcher’s effectiveness on the mound. It calculates the number of earned runs a pitcher allows per nine innings pitched.

WHIP and ERA are highly correlated, and in most cases, they fluctuate concurrently. In general, a lower WHIP value corresponds to a lower ERA value.

For example, pitchers who have a WHIP below 1.00 typically have an ERA in the low two’s or even less. This is due to the fact that WHIP considers the number of baserunners allowed per inning, while ERA only considers earned runs allowed.

When calculating earned runs, ERA considers any runs the pitcher is responsible for, disregarding the runs generated on unearned errors by fielders.

This is why ERA can be an unreliable statistic to evaluate pitchers, as one error from the defense can cause a run to be attributed to the pitcher unfairly.

Comparison of Baserunners Per Nine Innings and WHIP

Baserunners Per Nine Innings (MB/9) is another metric used to evaluate pitcher performance. As the name suggests, MB/9 calculates the average number of baserunners a pitcher allows per nine innings.

The difference between MB/9 and WHIP is that MB/9 considers all baserunners, including walks, hits, and hit-by-pitches, whereas WHIP only considers walks and hits. The two metrics are highly correlated, but they are not interchangeable.

MB/9 provides a more detailed picture of a pitcher’s performance, as it considers all baserunners, while WHIP looks at the number of hits and walks allowed only. Additionally, MB/9 has the advantage of giving us a rate statistic that considers the total number of innings pitched, thus providing the metric’s calculations per complete innings pitched.

Purpose of WHIP

WHIP serves as an essential tool in evaluating pitcher performance and analyzing a team’s chances at winning games. In this section, we will explore the purpose of WHIP further.

WHIP as a Predictor of Team Wins

WHIP has been shown to be a statistically significant predictor of team wins. According to a study of WHIP conducted by the Lahman Baseball Database, a 0.1 decrease in a team’s WHIP leads to a 2.1 increase in the team’s winning percentage.

This suggests that having pitcher(s) with low WHIP values is a crucial factor in a team’s success throughout the course of a baseball season. The study also revealed that the correlation between WHIP and wins was stronger compared to other performance indicators such as strikeouts and ERA, further emphasizing the importance of WHIP.

Top Pitchers Ranked by WHIP

Looking at yearly records and all-time totals, we can see that WHIP is an important metric in evaluating pitcher performance. Sandy Koufax’s four-year stretch from 1962 to 1965 is widely regarded as a golden era of pitching dominance, which is evidenced by his 0.885 WHIP during that stretch.

In the modern era, we see dominant pitchers such as Clayton Kershaw (career WHIP of 1.007) and Jacob deGrom (career WHIP of 0.983) leading the pack as far as WHIP is concerned.

Final Thoughts

WHIP is a vital statistic in evaluating pitcher performance and predicting a team’s success. There is a strong correlation between WHIP and ERA, thus making it essential in painting a picture of a pitcher’s efficiency on the mound.

While other metrics like MB/9 can provide more detail, WHIP remains a critical performance indicator in the sport of baseball. WHIP is a crucial performance metric used to evaluate pitcher performance in baseball.

Its calculation is straightforward, and a good WHIP score is generally below 1.1. WHIP is highly correlated with ERA, but MB/9 provides additional details on the number of baserunners allowed per inning. WHIP has limitations in accounting for errors, hit-by-pitches, and quality of defense.

However, WHIP is a powerful predictor of team wins and has been used to rank pitchers throughout history. Overall, WHIP remains a crucial tool to evaluate a pitcher’s efficiency on the mound and predict a team’s success in baseball.
