# What Does Fip Stand For In Baseball

## FIP

ERA Fielding Independent Pitching (FIP) calculates what a pitcher’s ERA would look like over a particular period of time if the pitcher had had league average results on balls in play and league average timing during that time period. In the early 2000s, Voros McCracken conducted research that found that the number of balls that fall into the batter’s box for hits against pitchers does not correspond well between seasons. As a result, pitchers have limited influence over the balls in play, and presuming that short-term changes in BABIP are due to the pitcher is likely to be erroneous.

It is a measure of a pitcher’s performance that excludes the effects of defense, luck, and sequencing.

Certain pitchers have demonstrated the capacity to produce lower ERAs on a continuous basis than their FIP indicates, but overall, FIP accurately reflects the underlying performance of the vast majority of pitchers.

Calculation: The formula for FIP is as follows: Formula for determining the fraction of time in which a person spends in the field = (13*HR + (3*(BB+HBP))-(2*K)/IP plus a constant The constant is used primarily to convert FIP to an ERA scale, and it is often about 3.10 in value.

Because FIP is built in such a way that the league average ERA and the league average FIP are the same, all you need to do to calculate the constant for any given year is the following: FIP Constant = (((13*lgHR)+(3*(lgBB+lgHBP))-(2*lgK))/lgIP) lgERA – (((13*lgHR)+(3*(lgBB+lgHBP))-(2*lgK))/lgIP) lgERA – (((13*lgHR)+(3*(lgBB+lg Having an understanding of how to compute the constant might be especially beneficial when you’re interested in performing some of your own calculations for data spanning numerous seasons.

• Run prevention is considered in the calculation of the individual weights for home runs, walks/HBP, and strikeouts.
• Why FIP is important: In the end, we want to employ statistics that will allow us to isolate the performance of the player we are aiming to study, rather than generalized statistics.
• This is because the number of runs a pitcher allows is also dependent on their defense, luck, and the sequence in which things happened (often called sequencing).
• The outcome of balls in play has been demonstrated to be almost totally out of the control of pitchers, thus while we care about how often a pitcher allows a ball to be put into play, whether a ground ball goes for a hit or is turned into an out is almost entirely out of their control.
• We worry about Batting Average on Balls in Play (BABIP) for a variety of reasons, one of which is because pitchers have very little influence over the BABIP they are permitted to allow.
• The pitcher who plays better defense will allow fewer hits and, as a result, fewer runs, yet the two pitchers were virtually comparable in their performances.
• A single, a single, a home run and an out are all it takes to allow three runs in a game with two outs.

To put it simply, FIP is an attempt to determine how well a pitcher actually did, regardless of circumstances outside of his control that contribute to statistics such as runs allowed.

However, these pitchers are rather infrequent, and FIP continues to be highly accurate while still remaining exceedingly simple.

However, there are certain limitations.

A pitcher’s FIP (Fielding Independent Pitching) is the same as their ERA (Fielding Independent Runs) when it comes to establishing comparisons between different players.

While FIP can be useful in determining how a pitcher will perform in the future, its use should be approached with caution.

In the long run, the vast majority of pitchers will have ERAs and FIPs that are extremely near to one another, but over the course of a season, these numbers can vary significantly from one another.

For example, pitchers who have the ability to minimize the running game or create fly balls at the price of line drives or ground balls are more likely than the typical player to beat their FIP.

The better bet if you have to choose between betting on an individual pitcher’s ERA or their FIP is to go with the latter.

FIP is an excellent statistic, but as is typically the case, delving deeper into the statistic’s components and other measures of pitcher performance can help you gain a better understanding of how a pitcher is genuinely doing.

Using the 2016 Run Environment as a guide Defense Independent Pitching Theory was the name of Voros McCracken’s research project (DIPS Theory). It serves as the foundation for most of the pitching analysis that is done today. It can be a difficult notion to grasp and one that is counter-intuitive to the majority of baseball fans. For additional details, please see our pages on DIPs, BABIP, and Luck & Chance. Because there might be a lot of volatility in tiny samples, FIP does a better job of forecasting the future than it does of measuring it in the present.

• That is not to say that it is not a retrospective statistic; rather, it is to say that it takes more than a handful of innings to be a valid predictor of performance, just as any other statistic would require as well.

View Glossary Entries Using a Specific Field Independent Pitching is a technique that transforms a pitcher’s three genuine outcomes into a statistic that is similar to his earned run average. Using the formula (13*HR+3*(HBP+BB)-2*K)/IP, adding a constant (often about 3.2) to put it on the same scale as earned run average, the earned run average is calculated as A component ERA inspired by Voros McCracken’s work on defense-independent pitching statistics, FIP has gained popularity due to its simplicity of computation – it requires only four easily-found box score stats, only basic arithmetic operations, and only four easily-memorized constants – as well as its ease of use.

Tom Tango and Clay Dreslough were the ones who came up with the idea, with the latter referring to it as the ERA (Defense-Independent Component).

It is important to note that the FIP constant we utilize is league and season specific; for example, a pitcher in the American League would have a different constant than a pitcher in the National League.

Based on the 2011 season, here is an example of the Fielding Independent Pitching spectrum: Roy Halladay’s performance was outstanding.

## Stat to the Future: Move over, ERA, it’s time for FIP

While playing fantasy baseball, you may have heard experts discuss how a hot pitcher from the previous season is “due for regression based on their peripherals.” If you’ve ever played fantasy baseball, you may have heard experts discuss how a hot pitcher from the previous season is “due for regression based on their peripherals.” While there are many factors to consider when evaluating players who might cool off after winning the Cy Young Award or great pitchers who have had mediocre seasons, one of the most straightforward is a metric known as Fielding Independent Pitching, or FIP, which is short for Fielding Independent Pitching.

It has the appearance of a comic book sound effect: When Spider-Man shoots a web towards the Green Goblin, a bright bubble appears, stating: “FIP!” This is true of many other sabermetric statistics as well (in fact, you could probably say the same about most of them).

## What is FIP?

FIP (Fielding Independent Pitching) is a statistic that is used to eliminate the impacts of fielding from the equation and only include the components of the game that the pitcher has control over, such as the strike zone. In order to evaluate a pitcher’s ability only on the basis of his or her ability to throw, it is necessary to remove fielders from the equation. Consider the following scenario: a pitcher allows three fly balls to the outfield. If the outfield behind the pitcher has outstanding range and all three fly balls are caught, the pitcher will be able to exit the inning with no earned runs on his or her record.

While identical fly balls and pitchers are involved, it is possible that due to the defense, the pitcher will wind up with two runs credited to their record, rather than none.

FIP is unaffected by balls in play, which are typically out of the pitcher’s control (although there is an exception to this rule, which I’ll address later in this article).

These outcomes are weighted according to their significance and then divided by the number of innings pitched, after which a FIP constant is applied.

## How to use FIP

If you’re acquainted with earned run average (ERA), then FIP is straightforward to understand: both FIP and ERA function on the same scale, with 5.00 being horrible, 4.00 being about average, 3.00 being good, and anything below 3.00 being in the Cy Young range. If you were to compare the FIP of a large number of pitchers to their ERA, you would discover that many of them have ERAs that are very near to their respective FIPs. John Smoltz finished his career with an earned run average of 3.33 and a fielding percentage of 3.24.

1. Pedro Martinez ended with an ERA of 2.93 and a WHIP of 2.91 in two seasons.
2. As a result, why not utilize FIP rather than ERA if they are basically equivalent in the long run?
3. Ordinarily, looking at an individual pitcher’s ERA and FIP over the course of a season will give you a sense of whether pitchers are over or underperforming.
4. It looked like Santiago was overperforming since he had done a bad job on the areas of the game that pitchers are expected to control: a FIP of 3.96 shows that he didn’t get many strikeouts and allowed a lot of walks, home runs, and HR/FB ratios, among other things.

Pitchers are not often able to maintain such a huge disparity between their ERA and FIP for extended periods of time, so it was no surprise that Santiago pitched to a substantially higher ERA in the second half of 2015 than he did in the first half of the year (5.47 in the second half as opposed to 2.33 in the first half).

FIP is a two-way street in which both parties benefit. In 2016, Michael Pineda threw to a 5.38 ERA and 3.77 FIP in the first half of the season, thus it wasn’t unrealistic to anticipate Pineda to throw to a lower ERA in the second half of the season. He did, and his rating dropped from 5.38 to 4.15.

## Warnings about FIP

We’ve already discussed the faults with ERA, but there are a few concerns with FIP that we should mention as well. For example, FIP does a terrible job of judging pitchers who throw ground balls or fly balls and do not strike out a large number of hitters. A ground-ball or fly-ball pitcher is primarily reliant on the support of their defense to keep them in the game. Their approach is to get batters to make weak contact so that they may be readily fielded by the defense. Despite the fact that it is a smart plan, FIP penalizes them for depending on their defense.

1. FIP may also be used to penalize pitchers by holding them accountable for home runs when there is a significant element of good fortune involved.
2. When it comes to fly balls, there’s a statistic called HR/FB percent that indicates what proportion of fly balls that are allowed by a pitcher end up leaving the park.
3. Most pitchers have an HR/FB percent of approximately 10 percent, while an unlucky pitcher may have an HR/FB percent of 16 percent (like Clayton Kershaw is doing this season).
4. Kershaw’s unluckiness is irrelevant to FIP, and as a result, he is undervalued as a result.
5. FIP is a highly useful statistic that, when utilized correctly, can be incredibly successful in determining a pitcher’s skill level and projecting how good of a pitcher they will be in the future if they are currently on the mound.

##### What is FIP?

Fielding Independent Pitching (also known as FIP) is a measure that is intended to provide us with information about a pitcher’s overall performance. FIP is a measure of occurrences that are directly under the control of a pitcher, such as strikeouts, walks, and home runs. A calculation is then used to scale these occurrences to a figure that is quite similar to the one you would see for the event rate of extinction (ERA). It is a “rate” statistic, which is similar to how many runs a pitcher may give up per nine innings if certain peripherals were taken into consideration.

According to Voros McCracken’s study on Defense-Independent Pitching (DIPs), Tom Tango devised the formula for Fielding Independent Pitching (FIP), which was published in Baseball Prospectus.

##### How to Calculate FIP

In terms of sabermetric statistics, the formula for FIP is straightforward, at least in terms of its application. It is calculated in the following manner: FIP = ((13*HR) + (3*(BB+HBP)) – (2*K)) / IP + cFIP = ((13*HR) + (3*(BB+HBP)) – (2*K)) / IP + cFIP A quick review of the variables is in order: HR = home runs allowed, BB = walks allowed, HBP = hits by pitches allowed, K = strikeouts, and cFIP = league FIP constant A variable that varies from year to year, the league FIP constant is used to compare FIP throughout the league to the same standard of excellence as ERA.

That constant was 3.048 in the year 2013.

Those correspond to the average linear weights of the occurrences in question.

##### Where to Find FIP

FanGraphs’ pitching statistics, which include FIP, are considered to be the gold standard. FIP is displayed on their basic player profiles and leaderboards*, which are updated on a daily basis during the season. Baseball Prospectus is another website where you may find it. * – – – – – – – – – – – – – – Among qualifying starting pitchers in the Major Leagues in 2013, Matt Harvey of the New York Mets held the league lead in FIP with a 2.50 mark. Who was the poorest among the qualifying starters for that particular season?

FIP is a term that is frequently used in baseball literature these days.

##### Using FIP in Analysis

So, what is the purpose of FIP? Most people believe that it represents what a pitcher’s earned run average “should” be. However, this is not entirely correct. FIP is scaled to ERA, and as such, its most useful application is as a basic description of the items that FIP measures, when placed in an ERA-scaled context. The earned run average (ERA) has additional factors that distort our ability to utilize it as a gauge of a player’s genuine talent level. ERA stats are likely to reflect a pitcher’s defense as well as his or her luck – especially when the sample size is limited.

1. FIP only records those events that are believed to be entirely within the control of the pitcher, reducing the amount of chance involved.
2. According to Tom Tango of The Book Blog: As a result, the goal of FIP is not to eliminate hits that are permitted or other non-HR contact plays, but rather to separate them into their own component (fielding-independent pitching, FIP).
3. And that is a nice outcome of our approach.
4. At the same time, FIP is not a legal document.
5. There are other pitchers that consistently underperform their FIP over extended periods of time.
6. If a pitcher’s FIP is a full run lower than his ERA in the midst of a season, there is a good possibility that the pitcher will have some positive regression and that their ERA will improve as a result of this.
7. Even though a season is a very small sample size, it is possible that regression will not occur – even throughout the duration of the entire season.

At the same time, it’s important looking at whether or not the pitcher has a track record of keeping his FIP below his ERA over a lengthy period of time. Perhaps there is something more at work that has to be taken into consideration, and FIP does not give the entire picture.

##### Associated Statistics

FIP-:FIP- is a statistic that compares a pitcher’s earned run average (FIP) to the league average (ERA). A FIP of 100 indicates that the player is on par with the league average. A FIP of 120 is a 20 percent decline from the league average. A FIP of 80 is a 20 percent improvement above the league average. Home runs permitted are replaced with home runs that should have been allowed in xFIP: Expected FIP (xFIP) was developed by Dave Studeman of The Hardball Times and is a regressed version of FIP.

PFIP: Predictive FIP (pFIP), developed by Glenn DuPaul over at The Hardball Times, is another modified FIP statistic that attempts to better precisely forecast future performance by reweighting the multipliers for the peripheral events and adjusting the constant from one season to the next.

## Why We Need to Be Cautious Using FIP

Peanut butter and jelly, biscuits and gravy, burgers and fries. ERA and FIP are all delicious combinations. It is now almost always seen alongside the most conventional technique of rating an individual pitcher, the earned run average (ERA), a measure that was earlier mostly unknown. In fact, some baseball commentators are going a step farther and referring to FIP as the only measure of success instead of ERA. In all likelihood, we are witnessing the transition from ERA to FIP as the “go-to” pitching metric.

Wrong.

It’s past time to put the brakes on the FIP train and re-examine exactly what FIP is and how it should be utilized in the most effective manner possible.

In the words of Fangraphs, Fielding Irrespective Pitching (FIP) is “a statistic that assesses a pitcher’s run prevention independent of the performance of the defense.” Essentially, the goal behind FIP is to track the outcomes of a plate appearance that can only be controlled by the pitcher himself, such as strikeouts, walks, hit by pitches, and home runs, among other things.

1. When opposed to the earned run average (ERA), the fielding-independent pitching (FIP) statistic performs a far better job of analyzing how well a pitcher did rather than merely calculating how many earned runs were scored while the pitcher was on the hill.
2. When ERA is used as a measure of predicted regression, positive or negative, FIP is used as a measure of expected regression, positive or negative.
3. a sharply hit ball down the line that landed foul by inches or a shot to straight-away center that the center fielder caught with his back against the wall).
4. Since its conception, FIP has been remarkably accurate in terms of projecting development or decrease for a pitcher, frequently at a common review point throughout the season like after the first month or at the All-Star break.
5. Here are only some of the ways FIP has been routinely misused: to compare pitchers, to assess pitchers’ careers, to estimate performance in future seasons, to replace BABIP, to defend pitchers who do not belong in the majors, and to evaluate relievers.
6. Why This Logic Is Flawed: This erroneous usage of FIP is by far the most widespread and most frustrating to those who understand what FIP properly measures.

Even two pitchers on the same team may be pitching on different days with different defensive alignments behind them, different infield/outfield shifts based on the opposing lineup that particular day – hell, at a ballpark like Wrigley Field, one pitcher could take the mound with a 20 MPH wind blowing straight out on a hot and sunny day and his teammate can toe the rubber the next day in the rain with a 20 MPH wind blowing straight in.

1. When comparing pitchers from various teams it becomes even more evident why FIP cannot come into play.
2. When comparing a pitcher of near identical caliber from the Diamondbacks to a pitcher on the Phillies, the pitcher on the Phillies will almost surely have the lower FIP, but that does not indicate he is the better pitcher.
3. For example, pitchers like Max Scherzer and Clayton Kershaw are likely to have very low FIPs since they are strikeout pitchers who will put down 8-10 players on strikes on an average day on the bump.
4. While the FIP model would say that Hendricks and Godley are the benefactors of solid defense behind them, and this may be somewhat accurate, it also requires talent and exceptional control to be able to create weak contact.
5. Why FIP Cannot Be Used To Evaluate Pitchers’ Careers: The Logic: Pitcher A has a lifetime FIP of 3.50 hence he had a very strong career.
6. Because no pitcher will pitch for a club with the exact same roster for the entire course of his career, and most pitchers will pitch for at least two different teams, FIP becomes useless when applying it to a pitcher’s career.
7. The odds that a pitcher throws 15 years without ever receiving a fortunate bounce, or without ever getting aid from a fantastic defensive play behind them, or without ever getting out of a jam are basically nonexistent.
8. However, if this is not the case, it is unreasonable to claim that the lifetime ERA of the pitcher at hand was somehow “skewed” owing to a disparity in ERA and FIP.
9. Why This Logic Is Flawed: One of the major misconceptions concerning FIP in general is that it is a projection, although FIP is, on the contrary, a predictive statistic.
10. However, to analyze a pitcher after a complete season and use FIP to estimate his performance next season does not make sense.

Because the elements that the pitcher could not control vary from season to season and will normally balance out over a long period of time, any significant difference in FIP for a full season is almost certainly due to the percentages of outs generated by the pitcher on balls in play versus via strikeouts.

1. Hendricks’s K/9 was just 8.05 and his HR/9 was only 0.71 — this would explain why his FIP was so considerably higher than his ERA.
2. While the fact that his ERA next season was 3.03 could appear counterintuitive to my theory, if we look at some of his other statistics we can demonstrate that the boost in ERA had nothing to do with his defense, luck, or sequencing.
3. That is exactly why every pitcher that has one season with a sub-3.00 ERA is not put in the Hall of Fame – sustaining that type of success as a pitcher is challenging.
4. When a pitcher has the type of ERA-FIP gap that Hendricks had in 2016, it is not realistic to use FIP as a forecast of how he will perform in future seasons.
5. Why FIP Cannot Be Used to Replace BABIP The Logic: Because FIP can inform us if a pitcher is anticipated to improve or deteriorate, there is no need for BABIP which serves the same goal.
6. Just like the finest pitchers of all-time tend to have a career BABIP of.300 or lower, the best hitters of all-time tend to have a career BABIP of.300 or higher.
7. Cabrera’s high BABIP may be attributed to the fact that he is one of the best hitters of all time and has consistently hit the ball hard throughout his career, making it much more difficult for the defense to field his pitches.

Due to the fact that BABIP only considers the variety of balls in play from a pitcher, but FIP considers every ball in play as the same, it is clear that these two statistics are highly different and should be handled as such.

His FIP, on the other hand, is 6.55, indicating that he has certainly been the victim of terrible luck, poor defense, and so on.

Unfortunately, in the case of pitchers who are experiencing epic struggles, the value of FIP becomes quite restricted.

It is automatically assumed by the FIP model that bad defense, bad luck, and bad sequencing are all impacting a pitcher’s performance to some level whenever he is giving up hits at a significantly greater rate than he is getting outs on balls in play, even though this is extremely unusual.

Last season, the relegation of Jon Gray to AAA was criticized since he had a 5.97 RA9 but only a 3.10 FIP.

While many people used his FIP to justify his poor performance, his 2.72 BB/9, 36.1 Hard percent, and 1.41 HR/9 were much more indicative of why he was struggling, although it should be noted that pitching in Coors Field almost always results in a higher HR/9 than normal.

Even though Gray shown glimpses of brilliance during the previous season, it was his inconsistency that led to his demotion, not any sort of “poor luck” as some who mentioned his FIP would have you believe.

Why This Line of Reasoning Is Incorrect: Tradition dictates that every starter will open the game with no runs on the board for the opposing team, every starter will start the game against the other side’s leadoff hitter, every starter will start the game with no runners on base for the opposing team, and so on.

• However, when it comes to relievers, there is no such consistency to be seen.
• Despite the fact that there are two drastically different situations in which a pitcher may find himself, FIP continues to treat every ball in play in the same manner.
• In the same way, a double in the first scenario would have little impact on the team’s chances of winning, but a double in the second scenario would have a significantly greater impact on their chances of winning.
• However, because FIP takes into account all balls in play in the same way, this statistic can be biased substantially in favor of relievers.
• In reality, during the course of Rivera’s career, the average difference between his ERA and his FIP was 0.58.
• More recently, Blake Treinen had a 1.82 earned run average despite having a 0.78 earned run average last season, making him arguably the best reliever in the game.
• The fact that the situation in which a reliever enters the game can vary so greatly, and that he is pitching significantly fewer innings per season than starters, it is irrational to apply the same FIP measurement to relievers as we do to starters is illustrated by this chart.
• There is one takeaway from all of this: we must be extremely cautious in how we use FIP because of several flaws in the statistical model that make it impractical to use in certain contexts.
• The FIP of a pitcher may be incredibly valuable in predicting regression and determining whether or not a pitcher’s production is sustainable.

As with any baseball statistic, it does not convey the entire story and should never be relied upon in isolation. If you like this post or have any questions or comments, please feel free to contact me through Twitter (@zorianbaseball) or Facebook.

## Back to Basics: What is Fielding Independent Pitching (FIP)?

Fielding Independent Pitching (FIP) is a statistic that, like the earned run average (ERA), is used to analyze pitching performance. FIP, in contrast to ERA, aims to distinguish between pitching performance and field performance/defensive performance. When it comes to pitchers, FIP may be very different from ERA, which can be quite informative. So let’s get started and learn more about what FIP is, how it’s calculated, and how you can utilize it to your advantage.

## What is FIP?

FIP (Fielding Independent Pitching) is a pitching measure that solely evaluates outcomes that are not influenced by defense. Because of this limitation, only those outcomes that the pitcher is directly responsible for are taken into consideration in the computation. These are some of the outcomes: These are the only outcomes taken into consideration because pitchers have very little influence over what occurs once the ball is put in play and becomes the duty of the defensive team. As previously said, we can’t just dismiss the number of hits, doubles, and triples a pitcher allows to go unpunished.

Based on league-average results on balls in play as well as league-average time, the constant is calculated.

## What is the Formula for FIP?

The FIP constant has been hovering around 3.10-3.20 for the past few years. You may get the values for each year by visiting this page (under column cFIP). The following formula may be used to determine the FIP constant on your own as well: FIP and ERA are two pitching statistics that are frequently used in combination with one another, thus it makes sense to include both in this computation (Read more below about their relationship). The goal is for the league average FIP from year to year to be the same as the league average ERA from year to year, if possible.

## How do you use FIP to evaluate a pitcher?

In the same manner as you would employ ERA! The lower the FIP, the better the pitcher’s overall performance on the mound. You should, however, compare the pitcher’s FIP to his ERA, which is something you should do. They should be fairly similar in appearance. It is recommended that you investigate the pitcher more if they differ by a large amount (1 or more). In the most fundamental sense, disparities arise as a result of:

• It’s possible that a pitcher’s FIP will be lower than his ERA if his defense is below league average. It is possible that a pitcher’s ERA is lower than his FIP if the pitcher induces more balls in play (poor contact or fly balls).

## How is FIP different from ERA?

The most significant distinction is that the earned run average (ERA) takes into account all earned runs, regardless of how they are scored. In contrast, FIP examines the methods through which runs are scored and isolates those that are directly attributable to the pitcher’s performance. The following is the formula for calculating ERA: However, while both the FIP and the ERA are useful and straightforward ways to evaluate a pitcher, it is demonstrated that the FIP is a more accurate indicator of the pitcher’s true pitching abilities.

### FIP Leaders vs ERA Leaders 2019

When we look at the top performers in the FIP against the top performers in the ERA in 2019, we see two quite different lists.

 FIP Leaders 2019 FIP ERA Leaders 2019 ERA Max Scherzer 2.45 Hyun-Jin Ryu 2.32 Gerrit Cole 2.64 Jacob deGrom 2.43 Jacob deGrom 2.67 Gerrit Cole 2.50 Charlie Morton 2.81 Justin Verlander 2.58 Walker Buehler 3.01 Mike Soroka 2.68 Hyun-Jin Ryu 3.10 Jack Flaherty 2.75

When we take a look at this group of players and compare their ERAs to their FIPs, we can see that the majority of them are not statistically significant.

 Player FIP ERA Difference (ERA-FIP) Max Scherzer 2.45 2.92 0.47 Gerrit Cole 2.64 2.5 -0.14 Jacob deGrom 2.67 2.43 -0.24 Charlie Morton 2.81 3.05 0.24 Walker Buehler 3.01 3.26 0.25 Hyun-Jin Ryu 3.1 2.32 -0.78 Justin Verlander 3.27 2.58 -0.69 Mike Soroka 3.45 2.68 -0.77 Jack Flaherty 3.46 2.75 -0.71

Positive readings imply that a player’s FIP is higher than his or her ERA. Among the pitchers at the bottom of the list, Ryu, Soroka, and Flaherty have the most substantial variances between their ERA and FIP, with Ryu having the largest gap (red text in table).

### Why do significant differences between ERAs and FIPs occur?

FIP is more commonly used to compare pitchers’ performance to their opponents’ performance than ERA since it reveals that their defense may be having an influence on their earned run totals. However, why would ERA ever be lower than FIP in the first place? This has everything to do with the sort of pitcher. The more often a pitcher creates weak/soft contact or more fly balls than the average, the more likely it is that his or her balls in play will result in outs. These sorts of pitchers can be considered exceptions to the FIP versus ERA discussion since their FIP alone does not provide a complete picture of their overall ability to succeed.

• Ryu is one of the most effective pitchers in the game when it comes to producing softer contact.
• He is an example of a pitcher whose FIP does not always convey the entire story about his performance.
• But when we look at Gerrit Cole and Jacob deGrom’s FIPs and ERAs, we can see that they’re quite close to one another.
• Using FIP alone would be a suitable and rapid technique of evaluating their abilities in this situation.

## Back to Basics

When a pitcher is on the mound, there are a variety of elements that influence the outcome of the game. Command and velocity are important factors in how well he performs on a day-to-day basis, but we must also consider luck and the performance of the defense. The chances of a pitcher getting more outs are higher if he has an all-star centerfielder in the outfield than if he has an ordinary centerfielder. Consequently, it is not entirely fair to compare those two pitchers because the results of their pitching were not entirely their fault in the first place.

That is exactly what the FIP is attempting to achieve.

After that, it focuses on the outcomes that may be directly ascribed to the pitcher’s style of pitching, and it isolates the results of the pitcher.

It is, on the other hand, a well-established indicator of a high-quality pitcher. Do you have any questions or concerns concerning the FIP? Please let me know in the comments section below.

## MLB Advanced Stats: What is FIP/xFIP?

FIP (Fielding Independent Pitching) is a measure of a pitcher’s performance on the mound that is similar to ERA.

## FIP Definition

FIP, on the other hand, only counts occurrences over which pitchers have complete control, including as strikeouts, walks, home runs, and balls in play. When a ball is hit into play, fielding is practically meaningless, as pitchers have little influence over what happens after the ball is hit into play. Instead, the FIP calculates what a pitcher’s ERA would look like if he had league-average defense and luck over his whole career. If a pitcher has a high average number of balls put in play, his FIP is likely to be lower than his ERA, which is a good thing.

## What About xFIP?

There is a comparable statistic to FIP called xFIP, which stands for Expected Fielding Independent Pitching and is used in the same way as FIP. Although, like FIP, xFIP is a more accurate predictor of a pitcher’s ability in the future than ERA, the two numbers differ in the manner in which they take home runs into consideration. Instead of using the number of home runs allowed in its equation, FIP employs the home run rate, which is determined by dividing the season’s Home Run to Fly Ball (HR/FB) rate by the number of home runs allowed in the calculation.

Despite their differences, both are intended to provide a more realistic picture of a pitcher’s performance than traditional measures such as the earned run average (ERA).

## FIP and xFIP in Betting

If you’re looking for value from a betting standpoint, FIP and xFIP may be quite helpful when seeking to separate a pitcher’s underlying performance in order to uncover value game to game. The fact that it doesn’t take fielding or chance into consideration makes it particularly suited for exploiting certain imbalances on the pitch.
