How to Calculate
The formula divides the number of fly ball hits by the total fly ball at-bats to get a ratio. For example, if a player has 15 fly ball hits out of 50 fly ball at-bats, the calculation is 15 divided by 50, which equals 0.300. This means the player gets a hit on 30% of their fly ball at-bats.
💡 Example
Suppose a player records 20 hits on fly balls during 70 fly ball at-bats. Using the formula, 20 divided by 70 equals approximately 0.286. This indicates the player has a batting average on fly balls of .286, showing solid effectiveness at converting fly balls into hits.

This statistic isolates a batter's performance on fly balls, which are batted balls hit in the air but typically not line drives or ground balls. Fly balls often have different outcomes than other batted ball types due to their trajectory and fielding opportunities. BAB Fly Balls helps evaluate how effective a hitter is at turning fly balls into hits, which can be influenced by factors like power, speed, and ballpark conditions. It provides more granular insight than overall batting average by focusing on a specific batted ball type.
⭐ Why It Matters
BAB Fly Balls is important because it isolates a hitter's ability to produce hits on fly balls, which often correlate with power hitting and slugging ability. Evaluating this stat helps teams and coaches understand a player’s batted ball tendencies and potential for extra-base hits. It also aids in identifying players who may be undervalued by traditional batting averages that do not differentiate batted ball types.
📜 Historical Context
The concept of analyzing batting average by batted ball type evolved with the advent of advanced tracking technologies like PITCHf/x and Statcast in the 2000s. Analysts sought to break down batting average into components to better understand hitting skills. While batting average itself dates back to the 19th century, BAB Fly Balls is a more modern derivative statistic developed to provide deeper insight into hitting performance.
📊 Historical Use
Historically, batting average on fly balls has been used by analysts to better understand a hitter's batted ball profile and power potential. It became more accessible with the rise of detailed batted ball data tracking in recent decades. Analysts and scouts have used this metric to identify players who excel at lifting the ball and finding gaps in the outfield, which can be critical for power hitters and those who rely on fly balls for extra-base hits.
🌟 Famous Examples
Players like Barry Bonds and Mike Trout have demonstrated high batting averages on fly balls, reflecting their ability to consistently turn fly balls into hits and extra-base hits. For example, Mike Trout has often posted BAB Fly Balls well above league average, showcasing his elite power and contact skills. These players exemplify how BAB Fly Balls can highlight a hitter’s ability to capitalize on fly ball opportunities.

⚠️ Limitations & Considerations
This stat does not account for the quality of the fly balls such as distance or hang time, nor does it differentiate between types of fly balls like pop-ups versus deep fly balls. It also excludes line drives and ground balls, which can be significant parts of a player's hitting profile. Additionally, environmental factors like ballpark dimensions and weather can influence outcomes, making BAB Fly Balls context-dependent.
