Baseball Swing Mechanics: What a Coach of College and Pro Hitters Teaches

By DITR staff · Updated November 14, 2026

Key takeaways

• Coach Su’a has coached hitters at the high school, college, professional and international levels for more than 40 years, and the same fundamentals show up at every level.
• The swing starts from the ground: legs and hips lead, then the trunk, then the hands.
• Balance and timing matter more than raw effort. A smooth swing beats a hard, off-balance one.
• Most swing problems trace back to the stance, the load or the stride, not the hands.
• Short, focused drills done often will fix more than long, unfocused batting practice.

What are the basics of baseball swing mechanics?

Baseball swing mechanics are the movements that take a hitter from a ready stance to a balanced finish. The basics are stance, load, stride, hip rotation, hands through the zone, contact, and finish. A hitter who does these seven things in order, with good balance, has a swing that can be repeated pitch after pitch.

Coach Murphy Su’a is a former NCAA Division I First-Team All-American at BYU who played in the Los Angeles Dodgers and Milwaukee Brewers organizations. He has spent more than 40 years coaching hitters at the high school, college, professional and international levels. His message to hitters is the same at every level: keep it simple, stay balanced, and let the body do the work.

This guide walks through each piece of the swing, what a hitting coach watches for, the mistakes we see most, and drills you can use on your own.

How do you hit a baseball step by step?

Here is the swing broken into the order a coach teaches it. Practice each step slowly first, then put them together.

1. Stance. Feet about shoulder width apart, knees slightly bent, weight on the balls of the feet. The head is level and both eyes are on the pitcher. The grip is relaxed, like holding a bird, not squeezing a hammer.
2. Load. The load is a small move back before the swing, usually a slight shift of weight toward the back leg and a small rotation of the hands. It gathers energy. It should be quiet and short, not a big wind-up.
3. Stride. The stride is a short, soft step toward the pitcher. The front foot lands closed or slightly open, never flying open. The head stays still. The goal is to land balanced with the weight still back.
4. Hip rotation. The back hip turns toward the pitcher, and the back foot pivots. The hips start the swing before the hands. This is where power comes from.
5. Hands through the zone. The hands stay close to the body and the barrel enters the zone on a short path. Think of the knob of the bat leading toward the ball, then the barrel whipping through.
6. Contact. The best contact happens out in front of the body, with the arms extended but not locked, and the eyes still on the contact point.
7. Finish. The swing ends with the weight on the front side, the belt buckle facing the pitcher, and the hitter balanced enough to hold the finish for a second.

If you only remember one thing, remember this: the lower body leads and the hands follow. Hitters who try to swing with only their arms lose power and consistency.

What does a hitting coach look for in a swing?

A good baseball hitting coach watches the whole body before looking at the bat. In our clinics and lessons, these are the things Coach Su’a checks first.

• Balance. Can the hitter stop at any point and stay steady? Falling forward or leaning back signals a timing problem.
• A still head. The head should move as little as possible from the stance to contact so the eyes can track the ball.
• Sequence. Do the hips start before the hands? If the hands go first, the swing loses power.
• Bat path. Is the path short and direct to the ball, or long and looping?
• Finish. A balanced, complete finish tells a coach the whole swing was working.

Video helps. A short clip from the side and from behind lets a coach and a player slow the swing down and see what the eye misses at full speed.

What are the most common baseball swing mistakes?

Most swing faults come from a few repeat offenders. Fix the early ones in the chain and the later ones often fix themselves.

• Over-striding. A long stride moves the head and drains power. Shorten the stride and keep the weight back.
• Pulling off the ball. The front shoulder flies open too early and the head moves away from the plate. Keep the front side closed a beat longer.
• Dropping the back shoulder. This often leads to weak fly balls. Keep the shoulders level through the load and stride.
• Casting the hands. The hands drift away from the body and the bat path gets long. Keep the hands close and take the knob to the ball.
• Gripping too tight. A death grip tightens the forearms and slows the barrel. A relaxed grip lets the bat move.
• Swinging too hard. Trying to crush every pitch breaks the sequence. Smooth is fast.

What drills improve baseball swing mechanics?

These three drills are staples in our work with hitters. Each one isolates one piece of the swing. For more drills across hitting, fielding and throwing, see our guide to youth baseball drills.

Drill 1: Tee work with a purpose

1. Set the tee at the middle of the zone, belt high, in line with the front hip.
2. Take your stance, load, stride, and swing through the ball into a net or fence.
3. Hold your finish for one full second.

What it fixes: balance, contact point and finish. Reps: two rounds of 10 swings, checking your finish each time.

Drill 2: Stride and hold

1. Take your stance and load.
2. Stride, then stop and hold the front foot down for a count of two without swinging.
3. Check that your weight is still back and your head is still. Then swing.

What it fixes: over-striding and drifting forward. Reps: 8 to 10 slow reps before any live swings.

Drill 3: Knob-to-the-ball

1. Stand in your stance with a bat, no ball.
2. Start the swing by turning the hips, and push the knob of the bat toward an imaginary ball.
3. Let the barrel whip through last and finish balanced.

What it fixes: casting the hands and a long bat path. Reps: 10 slow swings, then 10 at normal speed.

Quality beats quantity. Stop when your form slips. Tired swings teach bad habits.

How do college and pro hitters work on their swings?

College and professional hitters still work on the basics. The difference is the detail: they study video, test how their body moves, and fine-tune timing against different pitchers. Coach Su’a has worked with hitters at both levels, from his time at Cal State Dominguez Hills to the professional ranks, and the fundamentals remain the foundation at each.

At the Diamonds In The Rough Sports Foundation, Coach Su’a works one-on-one with high school, college and professional players. If you are looking for a baseball hitting coach in the South Bay, our one-on-one player development program is built around the individual hitter: video, drills, and a plan that fits the player’s body and goals.

Younger players can start with our free baseball and softball clinics, where the basics will be taught in a group setting.

How should hitters practice between lessons?

Short, regular practice works better than one long session. Ten to fifteen focused minutes with a tee, a net or a wall is enough to build a habit. Pick one thing to work on, such as a still head or a balanced finish, and stay with it until it feels natural.

Pair swing work with mindset work. Hitters who stay calm in the box and trust their preparation swing better under pressure. Our guide to the mental game of baseball covers routines that help. If you are getting ready for a tryout, read how players can prepare for baseball tryouts.
