When it comes to understanding baseball, there’s no shortage of stats that help fans and analysts break down the game. One stat that often comes up, especially when evaluating pitchers, is WHIP. But what exactly is WHIP in baseball? Whether you’re new to the sport or just want to get a better grasp on this important stat, this guide will help explain everything you need to know.
What Is WHIP in Baseball?
WHIP stands for Walks plus Hits per Inning Pitched.
It’s a pitching statistic that measures how many base runners a pitcher allows on average per inning. The stat adds up all the walks (BB) and hits (H) a pitcher gives up, then divides that by the number of innings they’ve pitched. The lower the WHIP, the better, as it means the pitcher is doing a good job of keeping runners off the bases.
WHIP is a valuable stat because it gives you a sense of how well a pitcher is controlling the game. Unlike some stats that rely on the actions of other players, WHIP focuses directly on what the pitcher can control: keeping runners from reaching base.
How Is WHIP Calculated?
Calculating WHIP is pretty straightforward. Let’s walk through the steps.
The formula for WHIP looks like this:
- WHIP = (Walks + Hits) / Innings Pitched
For example, if a pitcher has given up 30 hits and 10 walks over 40 innings, you would calculate their WHIP by adding 30 (hits) and 10 (walks) to get 40. Then, you divide that by 40 (innings pitched), which gives you a WHIP of 1.00. This means that, on average, the pitcher allows one base runner per inning.
A lower WHIP suggests that the pitcher is better at keeping opponents off base, which typically leads to fewer runs scored against their team.
Why WHIP Matters for Pitchers
In baseball, preventing runs is the name of the game for pitchers. WHIP is a key indicator of how well a pitcher is controlling the pace of the game and keeping opposing players from reaching base. While other stats like ERA (Earned Run Average) measure runs, WHIP gives insight into how many chances a pitcher is giving up to the other team.
Here’s why WHIP is important:
- Controlling the Game: Pitchers with a low WHIP are able to keep runners off base, which reduces the chances of the other team scoring. It’s all about minimizing opportunities for the opponent.
- Consistency: A good WHIP shows that a pitcher is consistently effective, not just getting lucky with a solid defense behind them. It’s a more direct measure of the pitcher’s ability to handle opposing batters.
- Evaluating Pitcher Performance: Managers and coaches often look at WHIP when making decisions about who to start in games, who to rely on in critical situations, and who might need more work in practice.
How Does WHIP Compare to Other Pitching Stats?
While WHIP is a crucial stat for evaluating pitchers, it’s not the only one. There are other pitching stats that offer different insights into a pitcher’s performance, and it’s important to look at the full picture when evaluating players.
Let’s compare WHIP to some of the other key pitching stats:
- ERA (Earned Run Average): While WHIP measures how many base runners a pitcher allows, ERA measures how many earned runs they give up per nine innings. ERA is a great indicator of overall effectiveness, but it can be influenced by factors outside the pitcher’s control, like defensive errors.
- Strikeout Rate (K/9): This stat shows how many strikeouts a pitcher averages per nine innings. Pitchers with high strikeout rates are often seen as dominant, but they might still allow a fair number of base runners, which is why WHIP is a useful complementary stat.
- FIP (Fielding Independent Pitching): FIP focuses on the outcomes a pitcher can directly control—strikeouts, walks, and home runs—while ignoring the impact of defense. It’s a more advanced stat that works alongside WHIP to provide a fuller picture of a pitcher’s performance.
Each of these stats has its place, but WHIP is one of the simplest and most direct ways to measure a pitcher’s ability to limit base runners.
What Is Considered a Good WHIP?
Just like with any stat, what’s considered “good” depends on the context. In general, though, a lower WHIP is always better.
Here’s a rough breakdown:
- Excellent WHIP: Below 1.00
- Very Good WHIP: 1.00 – 1.20
- Average WHIP: 1.20 – 1.35
- Below Average WHIP: Above 1.35
A WHIP below 1.00 is outstanding and usually means the pitcher is having an excellent season. Anything in the range of 1.00 to 1.20 is still very good and shows that the pitcher is doing a solid job of keeping runners off base. If a pitcher’s WHIP is above 1.35, they may be struggling to control the game and allowing too many runners to reach base.
It’s important to remember that these numbers can vary depending on the league, the level of play, and the ballpark. Pitchers in more hitter-friendly ballparks might have slightly higher WHIPs, while those in pitcher-friendly parks could see their WHIPs go down.
Famous Pitchers with Great WHIPs
Some of the best pitchers in baseball history are known not just for their strikeouts or low ERAs, but for their ability to keep runners off base. These pitchers have achieved legendary status partly because of their exceptional WHIPs.
Here are a few pitchers known for having great WHIPs:
- Clayton Kershaw: Throughout his career, Kershaw has consistently posted WHIPs below 1.00, a testament to his control and ability to dominate opposing hitters. His combination of strikeouts and pinpoint accuracy has made him one of the best pitchers of his generation.
- Pedro Martinez: Known for his overpowering fastball and sharp breaking pitches, Pedro Martinez consistently posted low WHIPs during his career. His ability to limit base runners was a big reason why he was so successful.
- Greg Maddux: Maddux wasn’t known for overpowering hitters with speed, but his control was second to none. His career WHIP of 1.14 reflects his ability to keep hitters off base and control the game.
These pitchers demonstrate how valuable a low WHIP can be in achieving success on the mound.
How WHIP Has Evolved Over Time
WHIP hasn’t always been a go-to stat for evaluating pitchers. In fact, it’s a relatively modern statistic that gained popularity as baseball analytics became more advanced. Originally, ERA was the most common way to judge a pitcher’s performance, but WHIP has become more widely recognized as a simple and effective measure of a pitcher’s ability to keep runners off base.
In today’s game, WHIP is used alongside other stats to give a more complete picture of a pitcher’s performance. With the rise of advanced analytics, teams are always looking for new ways to evaluate players, but WHIP remains a reliable stat that has stood the test of time.
Key Takeaways
So, what is WHIP in baseball, and why does it matter? Here’s a quick recap:

- WHIP is important because it provides a clear picture of a pitcher’s ability to control the game and limit opportunities for the opposing team.
- A lower WHIP is better, with anything below 1.00 considered excellent and anything above 1.35 indicating potential struggles.
- WHIP isn’t the only stat used to evaluate pitchers, but it’s one of the most straightforward and effective ways to measure a pitcher’s performance.
Understanding WHIP helps you appreciate the skill and strategy involved in pitching. Whether you’re analyzing your favorite team, following your fantasy baseball league, or just enjoying a game, knowing what WHIP means gives you a deeper insight into the art of pitching.
