Have you ever watched a baseball game and wondered how to truly tell if a pitcher is doing a great job? Beyond just looking at the score, there are so many numbers that help paint a clearer picture. One of those very important statistics, and perhaps one you don't hear about as often, is WHIP. It's a quick way to get a sense of how many opponents a pitcher allows onto the bases during their time on the mound.
This little stat, WHIP, stands for Walks + Hits per Inning Pitched. It basically tells you how many base runners a pitcher gives up for every inning they throw. Think of it like this: the fewer people getting on base, the less trouble a pitcher is likely to find themselves in, and that's usually a good thing for their team.
So, if you're curious about what makes a pitcher truly effective, or if you're trying to figure out if that young pitcher on your favorite team is really as good as they seem, understanding WHIP is a pretty big step. We'll explore what makes a WHIP number stand out, considering different levels of play and what else you might look at to get the whole story.

What is WHIP and How is it Calculated?
WHIP, as we talked about, is a measure of how many base runners a pitcher allows per inning. It's a pretty straightforward calculation, actually. You just add up the number of walks a pitcher gives up and the number of hits they allow. Then, you take that total and divide it by the number of innings they've pitched. So, it's (Walks + Hits) / Innings Pitched.
For example, if a pitcher walks two batters, gives up five hits, and pitches seven innings, their WHIP would be (2 + 5) / 7, which comes out to exactly 1.0. This number gives you a clear picture of how often batters are reaching base against a particular pitcher. It's a pretty useful way, you know, to see how efficient they are at keeping guys off the bags.
Some folks really like WHIP because it focuses on things largely within the pitcher's control: giving up hits and walks. It's a bit different from, say, ERA, which can sometimes be influenced by errors made by the defense behind the pitcher. This makes WHIP a favorite for many when trying to get a pure sense of a pitcher's ability to limit base runners.
Understanding a Good WHIP Number
So, what exactly makes a WHIP number "good" in baseball? Well, like many stats, it depends a little on context, but there are some pretty clear benchmarks that baseball folks tend to agree on. A lower WHIP is always better, since it means fewer people are getting on base against the pitcher.
General Benchmarks
When you look at the pros, a WHIP under 1.0 is considered very, very good. That means, on average, a pitcher is allowing less than one runner per inning. That's a truly dominant performance, indicating they are extremely effective at keeping opponents off the bases. You typically see numbers like that from the best pitchers in the game.
A WHIP around 1.2 to 1.3 is often seen as solid, a bit above average for a starting pitcher in the major leagues. If a pitcher's WHIP starts to creep up over 1.5, that might suggest they are struggling a bit with control or giving up too many hits. Sometimes, a WHIP over 2.0, which means ten hits and four walks in a seven-inning game, is still seen, but it's not what you'd call exceptional. It's a number that many starters have had, even really good ones like Scherzer last year, but it's not the mark of consistent dominance.
It's interesting to note that while a WHIP under 1.0 is truly outstanding, the idea of what constitutes a "good" WHIP is, in some respects, pretty consistent across different levels of play. The *meaning* of the number stays the same: fewer base runners. The *difficulty* of achieving that number, however, can change depending on the competition.
WHIP at Different Levels of Play
When you're talking about high school baseball, for instance, what's considered a good WHIP might look similar in terms of the raw number, but the context is different. A WHIP of 1.0 at the high school level is still really good, just like it is in the pros. However, the quality of hitting and defense can vary a lot more.
For example, a pitcher on a smaller school team with a WHIP of 1.0 might not have that same WHIP if they were playing on a big school team with tougher competition. The hitters might be better, and the defense might not be as strong, which could lead to more base runners. So, while the number itself is universally understood, the environment in which it's achieved matters quite a lot, you know?
It's about understanding the level of talent and support around the pitcher. A pitcher with a great WHIP at a lower level might still be very talented, but their numbers might adjust as they face better batters and perhaps different defensive situations. This is why coaches and scouts always look at more than just one stat.
WHIP for Starters Versus Relievers
A question that often comes up is whether the average WHIP differs between starting pitchers and relief pitchers. And if so, why? Also, does WHIP have different predictive value for starters versus relievers? These are pretty thoughtful questions, actually, and they highlight how context matters even within the same game.
Generally speaking, the best closers and relief pitchers will often have a lower WHIP than even the best starters. This is partly because relievers typically pitch fewer innings, often just one or two, and they're usually brought in for high-leverage situations where they need to get outs quickly. They often throw with maximum effort for those short stints.
Starters, on the other hand, have to pace themselves over many innings, sometimes six or seven or even more. They face the batting order multiple times, which can make it harder to keep their WHIP extremely low throughout a full game. So, while a WHIP under 1.0 is amazing for anyone, it's perhaps a bit more common to see slightly higher numbers from starters who are logging a lot of innings.
As for predictive value, WHIP is a pretty solid indicator for both. For a starter, a consistently low WHIP suggests they are good at limiting traffic on the bases over the long haul. For a reliever, it shows their ability to come in and shut down an inning without letting things get out of hand. In both cases, a low WHIP means the pitcher is doing their job well, you know, keeping runs off the board.
WHIP and Pitching Style: Groundball vs. Flyball
A pitcher's style can also influence their WHIP, and this is where other stats, like home run to fly ball ratio (HR/FB), can come into play. Some pitchers are known as "groundball pitchers," meaning they typically get batters to hit the ball on the ground a lot. Others are "flyball pitchers," meaning batters tend to hit the ball in the air against them.
A groundball pitcher will often result in more hits overall, because ground balls can find holes in the infield, leading to singles. However, they usually give up fewer home runs, since the ball isn't in the air as much. If you have a really good infield defense behind a groundball pitcher, you typically want to favor them because those ground balls will turn into outs, which can help keep their WHIP lower by preventing hits.
Conversely, if a team has a weaker infield defense, or a stronger outfield defense, they might prefer a flyball pitcher. Fly balls are either caught for outs or they go for extra-base hits or home runs. A good outfield can track down those fly balls, turning potential hits into outs. So, the ideal pitcher for a team, in some respects, depends on the strengths of their defense, and this can certainly impact their WHIP.
Looking at HR/FB numbers could be good for that purpose as well, helping you see if a pitcher is giving up too many long balls, which obviously hurts their WHIP by adding hits and potentially walks if they walk the next batter. It's all about how these different pieces fit together.
WHIP in the Bigger Picture: Other Key Stats
While WHIP is a fantastic stat, it's really important not to look at it in isolation. No single baseball statistic tells the whole story of a pitcher's performance. You should always use stats in conjunction with one another to get a complete picture. Saying a pitcher is better just because they have a lower WHIP or ERA is, well, not the smartest way to evaluate talent.
ERA (Earned Run Average) is another very common and useful stat. It measures how many earned runs a pitcher gives up per nine innings. A good ERA is generally anything under 4.0, but the best pitchers usually have an ERA below 3.0. ERA is a 9-inning average, while WHIP is an inning average, so they measure slightly different things. Sometimes, a good relief pitcher with a few bad outings could end up with an average or even subpar ERA, but still maintain a good WHIP if they're generally effective at limiting base runners.
Other stats that coaches and analysts often look at include:
- **First Pitch Strikes (FPS):** This shows how often a pitcher throws a strike on the first pitch to a batter. Getting ahead in the count is usually a good thing.
- **Pitches per Inning Pitched (#P/IP):** This helps measure a pitcher's efficiency. Fewer pitches per inning means they're getting outs more quickly.
- **Percentage of Strikes (% of Strikes):** Simply, how often they throw strikes.
- **Strikeouts per Walk (K/BB):** This ratio shows a pitcher's ability to get strikeouts while limiting walks. A high K/BB ratio is always a positive sign.
- **FIP (Fielding Independent Pitching):** This stat tries to measure a pitcher's performance based only on outcomes they control (strikeouts, walks, hit batters, home runs). It's more about underlying performance and predicting what a pitcher's ERA *should* be, rather than what it actually is. So, to learn more about pitching metrics on our site, you can explore FIP there.
For me, WHIP for a pitcher is comparable to OPS for a hitter. If I had only one stat to measure a pitcher, my choice would be Walks + Hits / Innings Pitched. But, you know, it's always better to use a few different tools to get the full scope. Looking at a combination of these numbers gives you a much richer understanding of a pitcher's true impact on the game.
Remember, stats are good to use in conjunction with one another. A pitcher's success can also be influenced by their team's defense and how many runs their team scores for them. If a pitcher comes in and their team plays great defense behind them and scores lots of runs, if they throw at all well, they'll likely have a great year, as long as the team doesn't change.

Frequently Asked Questions About WHIP
People often have questions about WHIP, especially when they're first getting to know the statistic. Here are some common ones:
Is WHIP a relatively new baseball statistic?
No, WHIP is not a relatively new statistic. While it might not be as commonly discussed in everyday conversation as ERA or batting average, it has been around for quite a while in baseball analysis. It's been used by scouts, coaches, and sabermetricians for decades to assess pitcher performance. It's just that it's gained more public attention in recent years as more people get into advanced baseball stats.
Is WHIP a good indicator of a pitcher's overall performance?
Yes, WHIP is a very good indicator of a pitcher's overall performance, especially concerning their ability to limit base runners. It directly measures how many batters reach base against them per inning, which is a fundamental aspect of pitching success. However, it's not the *only* indicator. As we've discussed, it's best used alongside other statistics like ERA, FIP, and K/BB ratio to get a truly comprehensive picture of a pitcher's effectiveness. It doesn't tell you about home runs allowed or defensive plays behind the pitcher, for example.
What statistical benchmark do coaches and scouts use for WHIP?
Coaches and scouts typically look for a WHIP under 1.25, and ideally under 1.0, as a strong benchmark for a truly effective pitcher, especially at the professional level. For high school or college, a WHIP around 1.0 to 1.5 is often considered quite good, depending on the league's competitive level. They understand that a lower number consistently means a pitcher is doing a great job of keeping traffic off the bases, which usually leads to fewer runs allowed. They also consider how that WHIP is achieved, looking at walk rates versus hit rates, and the quality of the contact allowed.
Why WHIP Matters for Pitcher Assessment
WHIP is a really telling stat because it gets right to the heart of a pitcher's job: preventing runners from getting on base. Every walk and every hit creates an opportunity for the other team to score runs. So, a pitcher who consistently keeps their WHIP low is essentially choking off those opportunities, which is a huge advantage for their team.
It’s a stat that reflects a pitcher's control and their ability to avoid giving up easy bases. It’s also less influenced by defensive errors than ERA, giving you a slightly purer look at the pitcher’s individual performance. For anyone trying to understand the nuances of baseball, keeping an eye on WHIP is a pretty smart move. It offers a clear, concise window into how well a pitcher is truly doing, more or less, at keeping the opposition quiet.
So, the next time you're watching a game, give a little thought to the WHIP. It's a key piece of the puzzle, and it can help you appreciate the real skill involved in pitching a great game. You know, it's a very simple ratio that tells a lot.
