Let’s talk about proper pitching mechanics for baseball pitchers...
Let’s face it:
As parents, we all want our son to succeed on the pitcher’s mound.
We also know that his success depends largely on his ability to have good control so that he is able to throw strikes and get hitters out.
Here’s the deal:
If pitchers can’t throw strikes, they won’t get much of an opportunity to pitch.
Plus, it’s not much fun pitching when you’re walking everybody.
But there’s more:
Besides having good control, pitchers also need to be able to throw hard and stay healthy.
So, what’s the secret to throwing strikes with good velocity while preventing injuries?
Proper pitching mechanics.
A solid understanding of quality baseball pitching mechanics and how the body works can help maximize performance and minimize the risk of arm problems.

The overarching goal of this information is to teach you the basic steps of getting beginners started correctly.
*To teach a pitching motion that allows the beginner to throw straight. The straighter the pitcher throws, the more success they will have. As confidence grows the more likely they will be to try to throw a bit harder.
*To teach a pitching motion that protects the elbow and shoulder. Special attention is paid to keeping the front shoulder closed and keeping the glove stabilized in front of the body which if not done correctly can result in early release of the baseball causing stress.
*To introduce pitching in a way that eliminates excess motion. The less motion introduced into the process, the more likely the pitcher is to maintain proper balance and mechanics.
*To simplify the delivery mechanics into a sequence that kids and their parents can quickly understand and repeat on their own. Basic and efficient pitching mechanics
Pitching a baseball is one of the most dynamic skills in all of sports.
During a pitch, shoulder internal rotation velocity reaches an incredible 7500±900°/s, making it the fastest human motion in any athletic activity.
Yet as highly skilled as pitching a baseball is, it’s also highly individualized—clearly, not all successful pitchers throw exactly alike.
In fact, a pitcher’s motion depends on many things such as his size, strength, balance, flexibility, leverage and coordination.
Put it all together, and it looks like this:
David Price has some of the most efficient and effective pitching mechanics in baseball.
Now, that’s a great pitch...
When teaching pitching mechanics or providing private pitching lessons, a coach should try to work within a pitcher’s own style, physical abilities, limitations and potential.
If a pitcher is successful, I encourage you to let him use his natural delivery unless:
*His mechanics create unnecessary stress or fatigue on the arm and are likely to cause an injury.
*His motion causes inconsistent control or inconsistent performance.
*His techniques limit his pitching potential.Have we heard from you yet? The 2021 National Baseball Pitching Survey is the most important poll we take all year. It’s just 5 questions. Take the survey now.Biomechanics of baseball pitching
Although pitching is a continuous motion that takes approximately 2 seconds, the biomechanics of the delivery can be separated into a series of phases to better understand, evaluate and analyze the movement patterns in the kinetic chain.
The following breakdown of the pitching motion into 13 steps is meant to be a guide for the parent who is instructing a young pitcher...
...or the coach who is attempting to make adjustments for a pitcher who is experiencing specific problems within his motion.
* In my opinion, kids 10 and under should pitch only out of the stretch initially to keep it simple. Simply illustrated, here’s why:Less movement = Less room for error = More efficient mechanics = Better velocity, accuracy and controlSequence of body movements in the pitching motionPhases1. Starting stance2. Wind up (Rocker step → Pivot)3. Leg lift (Forward rock → Knee up)4. Maximum knee height5. Stride6. Stride foot contact7. Arm cocking8. Maximum external rotation 9. Arm acceleration10. Release11. Arm deceleration12. Maximum internal rotation13. Follow-throughStep 1: Starting stance
In the starting stance, a pitcher should have good balance and keep his shoulders relaxed and body squared off to the plate.
The spikes of the pivot foot (pitching arm side foot) should be in front of the rubber and slightly open. The free foot (glove side foot) should be next to or slightly behind the pivot foot and about shoulder width apart.
Start with the hands comfortably at mid-chest or the belt. The pitching hand and wrist should be held deep inside the glove, hiding the grip and ball from the batter and coaches.
* Many pitchers have problems gripping the baseball properly due to lack of hand size, finger length or grip strength. Read this article to learn 13 different pitching grips young pitchers can use to be successful.
Lastly, a pitcher should keep his eyes fixed on the target to get the sign from the catcher. Stand tall, feel relaxed and take a deep breath.Steven’s pro tip
I’m often asked, ’Which side of the rubber should a pitcher stand on?’ If a pitcher throws right handed, I generally want him on the right side of the rubber. And if he is left handed, he should be on the left side. This position helps the pitcher stride in a straight line to home plate and also improves the angle of a breaking pitch from a RHP to a RHH, or a LHP to a LHH.Step 2: Wind up
Once the pitcher gets his sign from the catcher in the starting stance, he needs to initiate the pitching delivery with a simultaneous hand pump and rocker step. Hand pump
For the hand pump, a pitcher may choose to lift his hands over his head, over and behind his head, only to his chest, or keep his hands still.
If a pitcher has balance or coordination problems, he should lift his hands only to his chest or keep his hands still. Less movement means fewer things can go wrong.Rocker step
The rocker step is a small transfer of weight from the pivot foot (pitching arm side foot) to the free foot (glove side foot). This movement helps the pitcher shift his weight back briefly in order to put muscles on stretch to move forward, and should develop rhythm and tempo right from the start of the motion.
The rocker step should be a short step of no more than 3-6 inches straight back, at a 45° angle, or a 90° angle to the side.
While David Price steps directly to the side, most pitchers step back at a 45° angle rather than straight back because it makes it easier to position the lead foot in front of the rubber during the pivot.
However, I recommend you use the step back approach rather than stepping to the side. Stepping straight back allows the pitcher to keep his body in-line with the target while also building more momentum and thus create more potential velocity.
Regardless of which rocker step method is used, the biggest problem that most pitchers will have is not hesitating during the step back.
Keep the head in the center of the body—directly over the pivot foot—to stay balanced. Pivot
Following the rocker step, the body begins a squaring off maneuver called the pivot, during which the pivot foot is placed in a parallel position along the front edge of the rubber.
* Many pitchers have problems moon walking from one side of the rubber to the other during the rocker step and pivot because they take too big step of a step to the side. Remember to take a small rocker step of no more than 3-6 inches preferably straight back to eliminate unnecessary movements and keep the head directly over the pivot foot.
Remember, a RHP should pitch from the right half of the rubber, a LHP from the left half. Proper foot position on the rubber helps the effectiveness of various pitches by maximizing the angle of pitch approach to the hitter.Steven’s pro tip
During the rocker step and pivot, avoid any weight shift outside the midline. The midline is a line drawn from the middle of the back foot toward the target. Every time a pitcher moves his body away from midline, it requires another (extra) movement to get back along that same line, which disrupts timing and momentum.Step 3: Leg lift
Once the pivot foot has been positioned, the pitcher is ready for a forward rock into the leg lift.
As the leg comes up, make sure the pitcher lifts with the knee and does not swing up the foot, which puts many pitchers out of balance.
The lift leg foot should hang freely straight down from the knee.
The front hip rotates closed to a 90° angle or more, while keeping the weight back over a fairly straight firm posting leg to maintain balance.
Here’s a closer look at the leg lift:
Steven’s pro tip
Do not allow the body to drift forward until the lead leg knee reaches its maximum height, as described in the next step, and then starts to move downward into the stride.Step 4: Maximum knee height
As the pitcher lifts his knee up to maximum height, I recommend stopping the thigh slightly higher than parallel to the ground, but not so high that it causes a loss of balance.
The knee should also be angled back slightly over the rubber toward second base, which closes off the hips.
A good rule of thumb for most pitchers is that maximum knee height is somewhere between 60% and 70% of a pitcher’s body height.
Here’s a front pic of the top of the leg lift at maximum knee height:
And from the back:
A pitcher may lift his lead leg knee up higher than 70% to the chest area if he can maintain good balance.
That’s a BIG if, though.
Lifting the leg significantly higher than parallel requires it to come straight back down before it can move forward.
This extra movement increases the force required by the pitcher to move his body down mound as he starts to expand sideways along midline, and can prevent a pitcher from generating good forward momentum.
More times than not, a high leg lift does not improve velocity but only slows down forward momentum.
Explained differently, here’s how I recently described it to another pitcher in a post on my discussion forum:
During the leg lift up and at the top, keep a firm back leg; the back leg must not collapse during leg lift, nor prior to the stride toward home plate.
Coiling the body during knee lift or over-rotating at maximum knee height slows the pitcher down as he must now reposition his body sideways before he starts his movement toward the plate.
Remember, pitching is a linear activity or sideways activity.Steven’s pro tip
Don’t come to a ’balance point.’A 2004 study compared pitchers who used a balance point to those who did not and found that pitchers using a balance point had more head movement which resulted in lower velocity and decreased accuracy.
Having a balance point during the leg kick:
*Creates an un-athletic posture.
*Decreases quickness to the plate (decreased momentum = slower velocity).
*Slows delivery tempo (poor timing = decreased accuracy).Step 5: Stride
A 2013 study suggests approximately 50% of ball velocity in the pitching motion is the resultant forces accumulated in the stride.
Moving the body away from the rubber sideways and directing the entire pitcher’s mass at the target has the single biggest influence on final pitch velocity.
Remember this:
In order to produce maximum velocity, a pitcher must move his body as fast as possible in a side lunge going from the back leg to the front leg without stopping or hesitating.
Stride length, therefore, is a good indication of how fast the pitcher is moving away from the rubber, as well as his ability to build forward momentum—both of which contribute greatly to pitching velocity.
Once maximum knee height is achieved, the pitcher will start to stride along the midline to the target. This initial movement, characterized by the body moving sideways at the target, has the single biggest influence on final pitch velocity.
Proper posture
Check the pitcher’s posture: Is it upright?
Poor posture can restrict force production and add more stress on the arm; a pitcher who leans forward or backward will not direct his forces in the most efficient and effective manner at the target.
Good posture, however, allows the pitcher’s entire body mass to be directed toward the target.
To experience good and proper posture, a pitcher should stand with his heels, buttocks, and upper back against a wall while maintaining the natural curve in the back. The chin and nose should be positioned directly over the navel. The spinal alignment signals good posture and is what should be used in the delivery. It is important that through this brief but powerful movement toward the plate that the head, although turned to look at the target, be oriented directly above the body. That results in the trunk being positioned correctly to execute the next segment in the movement sequence and the accumulation of momentum begins with a very substantial contribution.
Proper posture is a great way to fix balance problems in young pitchers: When a pitcher understands what good body posture is and can maintain that along with keeping his head level, while moving faster, his balance problem will often disappear on its own. Lead with the front hip
In other words, get the butt out.
As the stride leg lowers, the front hip should lead the movement toward home plate while the stride foot should move downward and slide just above the mound surface.
Sandy Koufax summed it up best when he once said:
Leading with the hip as long as possible and the back leg were two of his keys for pitching success.
The focus for Koufax was to use a strong back leg drive to get his body and front hip moving faster and further toward the plate while his back leg drive provided stability, direction and the driving force of the body toward the target.
As soon as the leg starts down maximum knee height, the pitcher should aggressively drive away from the rubber leading with his front hip.
As a way of getting pitchers to understand the timing of this, the late pitching instructor Dick Mills once said, pretend there is an invisible coach behind the pitcher and at the moment the leg starts down from maximum knee height, pretend that the invisible coach is forcefully pushing the pitcher from the back hip aggressively forward.
I like that mental image.
This also serves to get pitchers to understand that the front hip should lead the shoulder.
Think of the stride as a skater lunge to the side.
In order to produce maximum velocity, a pitcher must move his body faster lunging sideways from the back leg to the front leg without stopping or hesitating while keeping his head positioned over the center of the upper body mass from the start of the movement until landing. Not knowing this commonly produces the error of the pitcher beginning the drive by leading with the front shoulder rather than the hip.
Here’s what good lower body mechanics for ’leading with the hip’ looks like:
Do you notice how the outside of the stride-foot ankle faces the target as early as possible—and for as long as possible?
Do you also notice when the lead leg starts down toward landing, it remains bent along midline rather than fully extended or swung around into the landing position?
The pitcher shouldn’t lean his head and trunk back (or curve his body forward) during the stride; he should maintain good upright posture throughout this sideways movement.Pitcher Arm Slots Game
The line of the spine should be vertical even though the head looks toward the target while the body is turned sideways. This will ensure the body moves forward as a single unit and influences force production maximally.
What I have observed in high velocity pitchers is that the weight is held back over a firm posting leg until the lead leg starts downward. The stride foot comes downward a little more than shoulder width apart and slides above the ground to the contact area.
The upper body and the head stay at the top center of the widening triangle of the body. It’s important to keep the head positioned over the center of the upper body mass from the start of the movement until landing.
During this step, there is no push off the rubber; the body should drift forward. Then once the stride foot has landed and stabilized the body, the hip flexors will pull of the back knee forward and inward off from the rubber.Steven’s pro tip
Early rotation of the hips during the stride can compromise a pitcher’s power production. There are generally two noticeable mechanical faults that occur when this happens:
*First, if a pitcher initially tries to turn his body back toward the outfield in an effort to gain more power before the weight shift, he will lose power. Rotation must occur over the front leg, and not the back leg. Any action that rotates the body before directing it toward the target wastes effort.
*Second, if a pitcher does not maintain flat foot ground contact long enough with his back foot, or if he does not direct his body sideways so the back foot rolls forward along with back hip, the heel may start to lift indicating a premature rotation of the hips. (Lifting the back heel can also occur if the pitcher swings his lead leg out and around in an arc before landing, instead of keeping the stride foot as close to midline as possible.)Stride direction
Measuring from the ball of the back foot directly to home plate, the ball of the stride foot should land within 2-3 inches across the midline. This direction helps to keep the front side closed and yet does not overly prevent good hip and trunk isolation. Stride length
Measuring from the front edge of the rubber to the toe of the stride foot, the length of the stride is usually close to the pitcher’s body height (83±4% of body height).
As previously mentioned, stride length is a good indication of how fast a pitcher is moving away from the rubber building forward momentum.
A long stride is not a problem if the pitcher can get his head and shoulders over the lead leg at the time of ball release.
What is most important, however, is that the pitcher is able to get his head and shoulders positione

Measuring from the ball of the back foot directly to home plate, the ball of the stride foot should land within 2-3 inches across the midline. This direction helps to keep the front side closed and yet does not overly prevent good hip and trunk isolation. Stride length
Measuring from the front edge of the rubber to the toe of the stride foot, the length of the stride is usually close to the pitcher’s body height (83±4% of body height).
