Fixing an Uppercut Swing: Getting on Top of the Ball
Pop flies, weak fly balls to the warning track, and swings under every fastball. The uppercut swing is one of the most common mechanical flaws in youth baseball, and fixing it unlocks an entirely different level of contact quality.

First, lets clear something up: some degree of upward barrel path is not only acceptable, its desirable. The ball travels downward from the pitcher toward the plate on a slight plane. A slight upswing matches that plane and creates more opportunity for square contact. This is the launch angle revolution and its backed by data.
The problem is when the upswing becomes excessive. When the barrel drops well below the hands early in the swing and the path becomes steeply upward, the margin for error shrinks dramatically. An excessive uppercut only hits the ball square at one specific height. Everything above it gets fouled back. Everything below it gets swung under completely.
This guide helps you distinguish between a healthy slight upswing and a problematic uppercut, diagnose the mechanical causes, and apply specific corrections that create a flatter, more direct barrel path without eliminating the natural upward tilt that generates power.
How to identify an excessive uppercut
Not every pop-up comes from an uppercut swing, and not every fly ball is a bad outcome. Before you start "fixing" a swing, you need to accurately diagnose the problem. Here are the telltale signs of a truly excessive uppercut.
Video signs (side view)
- •The barrel drops below the hitters belt before starting forward
- •The back shoulder dips significantly below the front shoulder at contact
- •The barrel path is steeply upward through the zone rather than level-to-slightly-up
- •The hands finish high above the back shoulder on the follow-through
Result signs (in games)
- •Consistently pops up fastballs at the belt or higher
- •Fouls back a high percentage of hittable pitches
- •Completely misses or swings under changeups and breaking balls
- •Hits fly balls that go high but not far (weak backspin rather than line drives)
- •Struggles with pitches above the waist

The three mechanical causes of an excessive uppercut
An uppercut swing is a symptom, not a root cause. To fix it, you need to identify which of the three common mechanical breakdowns is creating the steep barrel path.
Cause 1: Back shoulder dump
The most common cause of an uppercut is the back shoulder dropping excessively during the swing. When the back shoulder dips below the front shoulder, the barrel automatically goes below the hands and creates a steep upward path. The fix is maintaining a more level shoulder angle through the swing.
How to diagnose: Film from the front. At contact, the back shoulder should be roughly level with or slightly below the front shoulder. If theres a 15+ degree tilt, the shoulder is dumping.
Key drill: One-knee swings. Take your back knee and place it on the ground directly below your back hip. Swing from this position. The ground prevents your back shoulder from dropping because it locks your torso angle. Do 30-50 reps daily until the feel is grooved.
Cause 2: Early barrel dump
Some hitters let the barrel head drop below their hands too early in the swing. Instead of keeping the barrel above the hands as the swing starts, it loops underneath and then travels steeply upward. This creates a long, loopy swing with an uppercut finish.
How to diagnose: Film from behind (catcher view). If the barrel drops below the hitters waist before moving forward toward the pitcher, thats an early barrel dump.
Key drill: Knob-to-the-ball drill. Focus on driving the knob of the bat toward the pitcher first. The barrel stays above the hands longer when you lead with the knob. Take 20 slow-motion dry swings focusing on this feel, then gradually add speed.
Cause 3: Back leg collapse
When the back leg collapses or bends excessively during the swing, it drops the entire body lower. This creates a tilted axis of rotation that forces the barrel upward. The hitter is essentially swinging uphill because their body is tilted backward.
How to diagnose: Watch the back knee during the swing. If it buckles inward or drops toward the ground before contact, the back leg is collapsing.
Key drill: Back foot on a bucket drill. Place a small bucket or step behind your back foot. Swing while keeping your back foot elevated on the bucket. This prevents the back leg from collapsing and forces you to maintain a more upright rotational axis.
The four best drills to flatten your barrel path
These drills specifically target barrel path and create the proprioceptive feedback that teaches the body a more direct swing.
1. High tee work
Set the tee at chest height. You cannot get under a ball at chest height with an uppercut swing. The barrel must stay on plane to hit line drives. Take 25 reps at chest height, focusing on line drives back up the middle. Then lower the tee one notch at a time, maintaining the same barrel path feel at each height.
2. Two-ball tee drill
Place two balls on the tee: one on top of the other (use a stacked tee attachment or just balance them). The goal is to hit the top ball without hitting the bottom ball. This forces the barrel to travel on a direct path through the zone rather than scooping underneath. If you keep hitting the bottom ball, your path is too steep.
3. Flat bat swings
Take a paddle or flat bat and hit balls off a tee. A flat bat provides immediate feedback: if the barrel is steep, you get a weird contact feel and a pop-up. If the barrel is flat through the zone, you get solid contact. This tool exaggerates the feedback loop and accelerates the correction.
4. Inside-pitch drill
Set the tee on the inside part of the plate. An uppercut swing gets jammed on inside pitches because the barrel is slow getting to the zone. Hitting inside pitches forces a shorter, more direct path. Take 25 reps on the inside corner, focusing on pulling the ball with authority. The quicker hand path required for inside pitches naturally corrects an excessive loop.
The practice plan: fixing an uppercut in 3 weeks
Swing changes dont happen overnight. They require consistent, deliberate practice over several weeks. Here is a three-week plan specifically designed to flatten a steep barrel path.
Week 1: Awareness and isolation
Film your swing from the side. Identify which cause is creating your uppercut. Do the corresponding correction drill 50 reps daily. Do the high tee drill 25 reps daily. No live pitching this week. Tee and soft toss only. The goal is to build the new feel without the complexity of timing.
Week 2: Integration
Continue the correction drill (30 reps daily). Add front toss from 15 feet. The slow speed allows you to maintain the new barrel path feel while adding timing. Film yourself again mid-week to check progress. Begin mixing in regular BP at the end of the week.
Week 3: Transfer to competition
Correction drill as warm-up (20 reps). Full BP with focus on line drives. Scrimmage at-bats. The correction should be starting to feel natural. If you revert under pressure, thats normal. Take one step back and add more tee work before the next scrimmage. Film weekly to track the change.
Frequently asked questions
Is some uppercut okay in a swing?
Yes. A slight upward barrel path (7-12 degrees of attack angle) is optimal for line drives and home runs. The problem is when the angle exceeds 20+ degrees and creates a steep swing that misses fastballs and produces weak fly balls. The goal is not to eliminate the upswing. Its to control it.
Didnt the launch angle revolution encourage uppercut swings?
The launch angle revolution encouraged optimal launch angles (10-25 degrees for most hitters), which requires a slight upswing. It did not encourage steep uppercuts. The difference between an efficient 10-degree attack angle and a 25-degree uppercut is enormous in terms of contact consistency and bat speed.
How long does it take to fix an uppercut swing?
With daily focused practice, you can see measurable improvement in 2-3 weeks. Making the change fully automatic takes 4-6 weeks. The key is consistency: 50+ quality reps daily on the correction drills, not occasional marathon sessions.
Will fixing my uppercut hurt my power?
No. A more direct barrel path actually increases bat speed because the barrel travels a shorter distance to the ball. More bat speed equals more exit velocity. You will trade weak fly balls for hard line drives, which is an upgrade in every way. The hardest-hit balls in baseball come from level-to-slightly-upward swings, not steep uppercuts.

The three most common causes are: back shoulder dropping (dipping the back side during the swing), early barrel dump (the barrel head loops below the hands too early), and back leg collapse (the back knee buckles, tilting the rotational axis).\n\nEach cause requires a different correction. Filming the swing from the side and front views will reveal which issue is primary. Most hitters have one dominant cause, though some have multiple factors contributing to the steep path.
Look for these results: consistent pop-ups on fastballs at the belt or higher, inability to catch up to fastballs up in the zone, swinging completely under off-speed pitches, and fly balls that go high but not far.\n\nFilm from the side and watch the barrel path. A healthy swing has a slight upward tilt through the contact zone. An excessive uppercut shows the barrel dropping well below the hands before moving steeply upward.
The goal is not to overhaul the swing. It's to adjust the barrel path while preserving everything else that works. Small corrections like maintaining a more level shoulder plane or leading with the knob often produce dramatic improvements in barrel path without changing the hitter's timing, stance, or load.\n\nAvoid the temptation to rebuild from scratch. Focus on the specific cause and apply the targeted correction.
Yes. Bats that are too heavy for the player often contribute to an uppercut because the weight of the barrel pulls the hands down during the swing. If a young hitter's barrel consistently drops early, check the bat weight.\n\nA properly sized bat should feel light enough to control. The player should be able to hold the bat straight out with one hand for 15 seconds without significant shaking.
