Batted Ball Stat Tracker for Pitchers [Easy Tool for Tracking Fly Ball, Line Drive, Ground Ball Rates]

This is a batted ball tracker. It has 12 zones so you can chart left, center, right, for Fly ball, Line Drive, Ground Ball, and Popup. So, if a batted ball results in a flyball to center, you’d hit the plus button in the Flyball Center zone. This tool totals the data and puts a percentage breakdown in each zone and in output area below grid.

How to Use This Batted Ball Stat Tracker

This tool makes it easy to track batted ball outcomes for pitchers by breaking the field into 12 zones. The layout organizes these zones into four rows, with each row representing a different type of contact.

The first row tracks popups, the second row tracks fly balls, the third row tracks line drives, and the fourth row tracks ground balls. Each zone also includes a direction, showing whether the ball was hit to the left, center, or right side of the field.

Each zone has a plus and minus button that lets you adjust the count based on what happens during game play. Anytime a ball is put into fair territory, including home runs, you simply tap the plus button in the correct zone to record it.

***You should only record balls in fair territory (do not include foul balls even if they result in outs). Also, most stat keepers do not include bunts in batted ball data. Batted Ball Rate Calculator

If you make a mistake, you can tap the minus button to reduce the count. The tool keeps a running total in each zone as you add results.

The Output of This Tracker

I designed each zone to also display a percentage at the bottom of the zone, which shows the batted ball rate for that specific zone. That way you can not only track things like Line Drive Rate, but you can actually track it also for each specific zone.

The output area at the bottom of the tool calculates fly ball rate, line drive rate, ground ball rate, and popup rate, along with total counts for each category. A note will also appear next to each batted ball rate to compare it to MLB norms.

I added a copy button so you can copy or share the stats, and a print button lets you generate a hard copy. This batted ball tracker is designed to keep all data even if you refresh the page (so you don’t lose progress if you accidentally refresh page). If you want to clear the data, you will need to hit the reset button.

Understanding Batted Ball Rates in Baseball

Batted ball rates provide valuable insight into a pitcher’s tendencies and effectiveness. Every ball put into play falls into one of four categories: pop-up, fly ball, line drive, or ground ball. By tracking the percentage of each, teams and analysts can determine a pitcher’s strengths, weaknesses, and potential risks.

Pop-Up Rate (PU%)

Formula for Popup Rate in Baseball

This is the formula for popup rate in baseball:

Pop-Up Rate (PU%) = (Pop-Ups / Total Batted Balls) × 100

Pop-up rate measures how often a pitcher induces pop-ups, which are balls hit into the infield. Since infield pop-ups almost always result in outs, pitchers who generate a high number of them tend to be successful.

Pop Up Rate Range	Grade
Above 12%	Above MLB Norm
7% to 12%	Near MLB Norm
Below 7%	Below MLB Norm

However, pitchers with high pop-up rates often also allow more fly balls, which can lead to a higher home run rate. Pop-ups are not as commonly analyzed as other batted ball types, but tracking them is useful for distinguishing them from fly balls and understanding how well a pitcher controls contact.

Fly Ball Rate (FB%)

Formula for Fly Ball Rate in Baseball

This is the formula for fly ball rate in baseball:

Fly Ball Rate (FB%) = (Fly Balls / Total Batted Balls) × 100

Fly ball rate represents the percentage of batted balls classified as fly balls, which are hit into the outfield. This stat is often used to evaluate pitchers, as high fly-ball rates can lead to more home runs.

Fly Ball Rate Range	Grade
Above 39%	Above MLB Norm
32% to 39%	Near MLB Norm
Below 32%	Below MLB Norm

While some pitchers struggle with high fly-ball rates due to the risk of extra-base hits, others thrive by limiting home runs and taking advantage of fly ball outs, which occur more frequently than ground ball outs.

Line Drive Rate (LD%)

Formula for Line Drive Rate in Baseball

This is the formula for line drive rate in baseball:

Line Drive Rate (LD%) = (Line Drives / Total Batted Balls) × 100

Line drive rate measures how often a pitcher allows line drives, which are hit hard and at a lower trajectory than fly balls. Because line drives go for hits more often than any other type of batted ball, pitchers who allow a high percentage of them tend to struggle.

Line Drive Rate Range	Grade
Above 23%	Above MLB Norm
18% to 23%	Near MLB Norm
Below 18%	Below MLB Norm

Reducing line drive rates is crucial for limiting offensive production and keeping runners off base. A high line drive rate often means that hitters are consistently barreling the baseball while also on balance.

Ground Ball Rate (GB%)

Formula for Ground Ball Rate in Baseball

This is the formula for ground ball rate in baseball:

Ground Ball Rate (GB%) = (Ground Balls / Total Batted Balls) × 100

Ground ball rate represents the percentage of batted balls that are hit on the ground. Ground ball pitchers tend to give up fewer extra-base hits and home runs, making this style effective for limiting damage.

Ground Ball Rate Range	Grade
Above 49%	Above MLB Norm
42% to 49%	Near MLB Norm
Below 42%	Below MLB Norm

While ground balls result in hits more often than fly balls, they are less likely to produce significant run-scoring events. Pitchers with high ground-ball rates often rely on sinkers or two-seam fastballs to induce weak contact.

Why Tracking Batted Ball Data Matters

Using this batted ball tracker is critical for evaluating a pitcher’s effectiveness and understanding their approach to generating outs. There is no perfect batted ball distribution, but pitchers who allow a high number of line drives tend to struggle more than those who give up mostly fly balls or ground balls.

Since line drives go for hits at the highest rate, avoiding them is a key to success. Pitchers who consistently induce weak contact are more likely to limit baserunners and limit scoring opportunities.

The type of batted ball a pitcher allows can determine their overall success. Ground ball pitchers typically allow fewer extra-base hits but give up more singles (in comparison to fly ball), making ground balls more effective at limiting big innings.

Fly ball pitchers may surrender fewer total hits but are at a greater risk of allowing home runs (or other types of XBH). Some pitchers, though, do succeed by using high fly ball rates.

Ballparks also play a role in how effective certain pitching styles are. A pitcher in a smaller stadium with short outfield distance will likely struggle with a high fly-ball rate, while that same style could work well in a ballpark with deep fences.

Conversely, ground ball pitchers benefit from strong infield defenses and slower playing surfaces that make it harder for ground balls to turn into hits. Understanding the relationship between batted ball rates and stadium factors helps teams maximize their pitchers’ strengths.

By using our batted ball stat tracker, you can better evaluate a pitcher’s performance and identify areas for improvement. Whether a pitcher succeeds by keeping the ball on the ground or generating weak fly balls, understanding their batted ball profile is essential for predicting success and making strategic adjustments.
