TL;DR: Line drives are base hits 80% of the time, ground balls get on base over 40% of the time, and fly balls succeed less than 30% of the time. Teaching players to hit with a level swing instead of an upper-cut swing is one of the fastest ways to raise your team’s on-base percentage and drive in more runs.

What Is a Line Drive in Baseball?
A line drive in baseball is a batted ball that travels on a low, straight, nearly flat path directly from the bat toward the field, without a high arc or an immediate drop to the ground. It is the result of a batter making square, level contact with the ball, sending it hard and flat through the air. Because the ball stays low and moves fast, fielders have very little time to react, which is why line drives become base hits roughly 80% of the time according to NCAA Division 1 data.
Line Drive vs Fly Ball: Which Is Better?
A line drive is far more likely to become a base hit than a fly ball, with line drives reaching base 80% of the time compared to fly balls reaching base less than 30% of the time, including home runs. Fly balls travel high in the air, giving outfielders time to move underneath them, track their path, and make a routine catch. Line drives stay low and move fast, giving defenders almost no time to adjust. For players who want to get on base consistently, hitting line drives is the smarter goal.
| Batted Ball Type | Base Hit Rate | On-Base Rate | Why It Matters |
|---|---|---|---|
| Line Drive | ~80% | ~80% | Ball moves fast and low, little reaction time for defenders |
| Fly Ball (including home runs) | ~20% | Under 30% | High arc gives outfielders time to track and catch the ball |
A common mistake young players make is believing that hitting the ball high means hitting it far. A ball hit with an upper-cut swing does go up, but it also comes straight back down, often landing near the shortstop position and rolling to a stop still in the infield. A ball hit with a level swing stays low, bounces through the infield, and can roll all the way to the outfield fence.
Line Drive vs Ground Ball: How Do They Compare?
Line drives are more effective than ground balls, with an 80% on-base rate compared to a ground ball on-base rate of over 40%, but both beat fly balls by a wide margin. Ground balls force the defense to field cleanly, throw accurately, and catch the ball at first base, which means more things can go wrong for the defense and right for the batter. Line drives skip the ground entirely, removing the fielding step and reducing the defense’s time to react even further. The best approach is to aim for line drives while knowing that hard ground balls are still a solid outcome.
| Batted Ball Type | Base Hit Rate | On-Base Rate |
|---|---|---|
| Line Drive | ~80% | ~80% |
| Ground Ball | ~30% | Over 40% |
| Fly Ball (including home runs) | ~20% | Under 30% |
Ground Ball vs Fly Ball: Why Grounders Win
Ground balls result in the batter getting on base over 40% of the time, while fly balls result in the batter getting on base less than 30% of the time, making ground balls the better outcome in most situations. When a batter hits a grounder, the fielder must cleanly field it, make an accurate throw, and have another fielder make a clean catch. That is three separate chances for an error or misplay. Fly balls, on the other hand, are easier for defenders to track, get underneath, and catch in one smooth motion. Ground balls create pressure and chaos for the defense. Fly balls give the defense a clean play to make.
Line Drive vs Hard Ground Ball: What Is the Difference?
A line drive stays in the air on a flat trajectory after leaving the bat, while a hard ground ball hits the turf almost immediately after contact and skips through the infield at high speed. Both are the result of a level swing and solid contact, and both give the defense problems. A line drive is harder to catch because it moves through the air quickly with no bounce to slow it down. A hard ground ball causes problems because it moves fast along the ground, forces the fielder to bend and field cleanly, and still requires an accurate throw and catch to record an out. Either outcome from a level, square swing is far better than a fly ball.
What Is a Line Drive in Softball?
A line drive in softball is the same as in baseball: a batted ball that travels on a low, straight, flat path directly from the bat, the result of level contact between the bat and ball. The term and the concept apply equally to softball. Batters in softball who develop a level swing and make square contact will produce line drives that are harder for fielders to track and catch, raising on-base percentages just as they do in baseball. Upper-cut swings in softball produce the same problem they do in baseball: the ball goes up, comes back down, and gives the defense an easy play.
How to Hit Line Drives in Baseball
To hit line drives in baseball, use a level swing that makes square contact with the ball rather than an upper-cut swing that scoops under it. When your swing path is level, the bat meets the ball face-on, sending it out on a flat, fast trajectory. When your swing is an upper cut, the bat comes up under the ball, launching it high in the air on a steep arc that comes right back down. The most direct fix is to stop the upper-cut habit early and train a level, downward swing path.
One proven drill for this is the Don’t Hit the Chair Drill. Place an old folding chair slightly behind a batting tee. Practice hitting the ball off the tee without hitting the chair on your follow-through. Set the tee a little lower than the chair seat so your swing naturally moves in a downward motion. Use an old bat for this drill. The chair forces you to drive through the ball on a level path rather than swinging up and around it. This drill is especially useful for young players who have already developed an upper-cut habit.
Practicing in a good batting cage setup helps reinforce the right swing path over hundreds of repetitions. The Original Big Bubba Batting Cage, USA’s #1 Selling Baseball Turtle, gives players a structured space to work on level swing mechanics consistently.
How to Hit More Line Drives in Baseball
To hit more line drives in baseball, focus on three things: a level swing path, square contact with the ball, and early correction of any upper-cut habit. Upper-cut swings feel powerful because they launch the ball high, but the data is clear: fly balls turn into outs roughly 80% of the time. Line drives turn into base hits roughly 80% of the time. The goal is to convince your players, especially younger ones who believe high hits go far, that a flat, level swing produces better results.
A simple experiment proves it. Let a player hit their way with an upper cut, measure where the ball lands, then have them hit with a level swing and measure again. The level swing will send the ball much farther along the ground and into the outfield. Seeing that result firsthand is often all the motivation a young player needs to change their swing for good.
High on-base percentages followed by solid hits are what win ball games. Build those percentages by training your players to target line drives and hard ground balls over fly balls every time they step up to the plate.

Frequently Asked Questions
What counts as a line drive in baseball scoring?
A batted ball is scored as a line drive when it travels on a low, nearly flat trajectory directly from the bat through the air. It does not arc high like a fly ball and does not hit the ground immediately like a ground ball. Scorers and coaches generally define it as a hard, flat batted ball that stays in the air on a straight line.
Is a line drive better than a ground ball?
Yes, based on NCAA Division 1 data, line drives are better than ground balls. Line drives result in the batter getting on base about 80% of the time, while ground balls result in getting on base just over 40% of the time. Both are much better than fly balls, which produce an on-base rate under 30%.
Why are fly balls easier for the defense to catch than line drives?
Fly balls travel in a high arc, giving outfielders time to watch the ball, read its path, move into position, and wait under it for an easy catch. Line drives move fast and stay low, leaving fielders almost no time to react or adjust before the ball passes them.
What causes an upper-cut swing in young players?
Young players often develop an upper-cut swing because they believe hitting the ball high means hitting it far. They swing upward to try to launch the ball, which puts the bat under the ball instead of meeting it squarely. The result is a fly ball that goes up and comes back down rather than a line drive that travels flat and fast through the defense.
How does the Don’t Hit the Chair Drill work?
Place an old folding chair slightly behind a batting tee. Set the tee a little lower than the chair seat. Hit balls off the tee without making contact with the chair on your swing. The chair forces a downward, level swing path because any upper-cut motion will cause the bat to hit the chair. Use an old bat for this drill.
Do line drive principles apply the same way in softball?
Yes. A line drive in softball is the same concept as in baseball: a low, flat, fast batted ball that results from a level swing and square contact. Softball hitters who develop an upper-cut swing face the same problem baseball players do, producing fly balls that give the defense easy outs. A level swing in softball produces the same line drive benefits.
What is the fastest way to get a young player to fix an upper-cut swing?
Show them the results side by side. Let the player hit with their upper-cut swing and measure where the ball lands. Then have them hit with a level swing and measure that result. The level swing will send the ball much farther along the ground and into the outfield. Seeing the difference firsthand is usually enough to motivate an immediate change. Follow up with the Don’t Hit the Chair Drill to reinforce the new swing path.
Train the Right Swing with the Right Equipment
Consistent practice is what turns a level swing into a habit. A quality batting cage gives your players the space to repeat the right mechanics hundreds of times.
