BABIP Guide for 2026
Sam Navarro-Imagn Images

If you listen to or watch any baseball or fantasy baseball radio or TV, you will hear BABIP.  It is an acronym for Batting Average Balls in Play.  It sounds complicated to those who don’t use a lot of metrics, but it is simple and an amazing indicator for both hitters and pitchers.  In this article, I will break down what it means and how you should use it as a guide.  It is not always applicable to all players, but with a small amount of work, you can figure out how to use it for your fantasy baseball teams.  It is especially useful for leagues where your league mates stick to the standard statistics to determine their draft and in-season play.

This guide walks through what BABIP means, what normal levels look like, and how you can make SMARTfantasy baseball decisions using it in drafts and during the season.

What BABIP Measures

The Simple Formula

As complicated as it seems, it is a simple formula:

BABIP = (Hits – Home Runs) / (At-Bats – Strikeouts – Home Runs + Sacrifice Flies)

So, my first thought when we looked at this about 10 years ago was: if we remove home runs, we are missing a major part of why a player is good.  Also, if we take out strikeouts, aren’t we removing something that is a negative?  This is why you cannot use this for all players.  A player like Kyle Schwarber, cannot be identified by this metric for example.

What BABIP Is Actually Telling You

The reason we start with BABIP is that it is one of the hardest to understand but once you do, it can deliver results for you both in your draft and in-season.  Whether it is a minor injury, loss of confidence or just seeing the ball well for a period of time, players tend to hit in streaks. Add to that the elements of “luck” and you have great differences for a hitter.  

For pitchers, the “luck” element is even greater.  A pitcher’s ERA can go up just based on a couple of “lucky” singles with runners in scoring position (RISP).  Hitters hitting the ball on the ground and it going through the infield can affect either hitters or pitchers and this metric help you understand which players are getting lucky.

What Is a Normal BABIP?

League Average and Why It Matters

Most hitters settle around the league average BABIP over time, which is .305. Depending on a player’s skills that can be very different.  A speedy slap hitter who hits a lot of ground balls will have more of them result in singles that a slow plodding fly ball hitter.  When the latter hits it on the ground, he is usually out.  The league average matters for players who do not have a long enough history to identify the players average BABIP.  That is the metric you should use when figuring out where the opportunity is.

So, to be clear, just because someone has a low BABIP, does not mean he was unlucky unless his recent three years shows you that he normally has a high BABIP.  The opposite is true also of course.  A hitter is not automatically labeled lucky if he has a .350 BABIP unless his average BABIP is average or below.

Using BABIP for Hitters in Fantasy Baseball

Spotting Luck vs. Skill

BABIP can tell you a lot about hitters.  When you see a hitter batting .330 with a BABIP of .420, that’s a heavy sign that they will more than likely cool off. Even the best hitters cannot maintain a BABIP anywhere close to .400+ for long.

On the other hand, a player hitting .200 with a .220 BABIP is due for improvement. You first need to check that they are not simply lost at the plate.  I watch a couple at bats as MLB At Bat has them easily available, but if you don’t have the time, look at hard contact, chase rate or BB% to make sure that they still have plate discipline.

If their contact quality looks good and their history suggests they’re usually at or above the league average (.305), you are looking at a buy-low candidate. These are the players fantasy managers love to target early in the season.

BABIP is also helpful during drafts. A breakout 2025 season with a high BABIP can mean that he was lucky.  This is especially true for batting average leaders. 

Conversely, a player who slumped in 2025 but had an unlucky BABIP will be undervalued in 2026 fantasy baseball drafts.

Examples of Application

  • Let’s look at George Springer who hit .309. He had a .340 BABIP when his average BABIP for the last three seasons was around .270.  This usually means next season that his batting average will drop by 20-30 points.
  • Now, we look at Sal Perez who hit only .236.  He had a BABIP of .259 when his average is close to the league average.  That means he should increase his batting average by 20-30 points to .270 or .275 which is a league winner.

Using BABIP for Pitchers

Why Pitcher BABIP Is Different

BABIP works very differently for pitchers. While hitters' BABIP varies based on their skills, pitchers don’t control this stat. Defense, positioning, and ballpark conditions play a much bigger role.

Most pitchers settle near the league-average BABIP over time, so any extreme high or low number usually suggests that regression is coming. A pitcher with a 2.80 ERA but a .230 BABIP probably had a lot of batted balls were influenced by the team defense or ballpark. That doesn’t mean they’re bad, but it means their ERA is misleading. A pitcher with a bad ERA but a .350 BABIP might be better than their stat line looks.

The key is to use BABIP alongside other metrics such as Expected Fielding Independent Pitching (xFIP). This stat estimates what a pitcher "should" have done based on things they can control, like strikeouts, walks, and home runs. When both metrics tell the same story, you can make more confident fantasy baseball moves.

Conclusion

BABIP is one of the best introductory analytics tools for fantasy baseball. It’s hard to learn, but easy to apply, and it helps you avoid mistakes misreading player performance. As you prepare  for the 2026 fantasy baseball season, add BABIP to your evaluation process. When you see a bad batting average for a good hitter, check to see if he was unlucky.  If you see a bad ERA for a good pitcher, check to see if he was unlucky.

Remember, it is better to be lucky than good, but it never lasts.  Knowing who was lucky will give you an edge.
