If you're looking for proven ways to increase pitching velocity based on science, you're going to love this article.
A pitcher's ability to increase velocity and maximize ball speed while avoiding shoulder and elbow injuries is an important determinant of a successful career.
For as long as baseball has been played, hard-throwing pitchers have been part of the lore and lure of the game.
We cared about velocity even before we could measure it with modern technology today.
Back in 1912, a pitcher named Leslie Ambrose Bush often walked more batters than he struck out, but he threw so hard he earned the name Bullet Joe. In 1917, a Negro League pitcher named Joe Rogan became Bullet Rogan and went all the way to the Hall of Fame.
Walter Johnson's fastball "hissed with danger," Ty Cobb said. A hundred years ago Johnson's fastball was timed not with a Bushnell, Jugs or Stalker radar gun, but rather against a speeding motorcycle and estimated at 97 mph.
Thirty years later, Bob "Rapid Robert" Feller took the same motorcycle test and his fastball was estimated at 104 mph.
MLB's hardest throwers
There's a general consensus that major league pitchers are now throwing harder than ever before and the same holds true for amateur pitchers.
Even over the last seven years, data compiled from MLB's very accurate PitchFX system tells a story of more pitchers throwing harder each year.
Take a look at 2007, when only eight major league starters averaged 95 mph or better on their fastball. The number jumped to 15 by 2012 and to 20 in 2014.
The same goes for relievers, with 27 throwing 95 mph or better in 2007, and 54 at 95 or better last year – an increase of 50% in just 7 years.
There's no consensus on why pitchers are throwing harder today, but there are plenty of theories: Pitchers are getting bigger and stronger, with better deliveries learned and perfected at younger ages, and they're also able to set velocity goals for themselves and measure results to work to meet them.
This combination of good strength while maintaining flexibility, good pitching mechanics, and good throwing programs to build speed, stamina and a strong arm are the main factors to MLB pitching velocities that are truly off the charts.
Take a look at the hardest throwers in baseball since 2007...
|Starters (200 pitch minimum)||Average velocity (mph)|
|Relievers (200 pitch minimum)||Average velocity (mph)|
What's impressive about these 10 pitchers is not just putting up three digits on the radar gun but the consistency of their velocity as well... these numbers are averages.
Increasing pitching velocity
An explosive fastball alone can still get a pitcher to college and entry in to pro ball, while wowing coaches, scouts, players and fans along the way. (Velocity is a foot in the door. Other variables like good control, command, movement and changing speeds are still needed, however, to pitch at these levels.)
So how can your son develop a better fastball?
Here are 22 ways to improve pitching velocity to point you and your son in the direction of success:
1. Increase body mass
When I was growing up, I was on the skinnier side so my Dad used to preach Mass = Gas, which usually meant it was time for another peanut butter sandwich. It became a long running joke between us throughout my baseball career.
But research has now proven there's a lot of truth to this statement.
Gaining weight through both growth spurts and eating 500 extra calories per day can help to improve a pitcher's ability to throw harder.
However, it's important to remember that adding mass is a slow process. According to the Mayo Clinic and the McKinley Health Center at the University of Illinois, a healthy weight gain is 1/2 to 1 pounds per week. Adding 10-15 pounds of lean mass can take 6-8 months or more.
2. Speed up the time from stride foot contact to maximum external rotation of the throwing shoulder
The hardest throwing pitchers in baseball go from stride foot contact (SFC) (left picture) to maximum external rotation (MER) (right picture) in less than 3-tenths of a second, or 0.244 seconds to be exact.
I'll cover MER in greater detail below.

3. Get the glove arm involved
Good glove arm action helps proper shoulder alignment, trunk arching and flexion, and good trunk rotation—all of which generate arm speed and ball velocity.
There are two basic methods of developing effective glove arm action:
1) Fire the glove and lead arm toward the plate
2) Lead the elbow directly at the plate (pictured above)
For both methods, once the stride foot makes contact with the ground, actively whip the glove and elbow down and back outside the lead hip. Do not allow the glove to go too far behind the lead hip.
4. Eliminate the "balance point"
Do you notice in this slow-motion video that Justin Verlander doesn't stop or pause at any point during the peak of his leg lift? (He also doesn't throw a strike.) But the path of his knee is a fluid, continuous motion up and down.
A 2004 study compared pitchers who used a balance point and those who did not. Researchers found that pitchers using a balance point had more head movement which resulted in lower velocity and decreased accuracy.
This led the researchers to conclude, "we cannot recommend the indiscriminate practice of the balance-point position..."
Having a balance point during the leg kick does the following:
- Creates an un-athletic posture
- Decreases quickness to the plate, reduces momentum and causes slower velocity
- Slows delivery tempo, leading to poor timing and decreased accuracy

5. Raise lead knee to a minimum of 60% (but not more than 70%) of pitcher's overall height during leg kick
Research indicates that the hardest throwing pitchers have a maximum lead knee height between 60 and 70 percent of their standing height.
If the lead knee isn't raised high enough (< 60 degrees), it prevents the pitcher from getting good momentum with the stride leg toward home plate. If the lead knee is raised too high (> 70 degrees), the momentum down and toward the plate can be arrested or started too late.

6. Increase knee flexion at foot strike
Research indicates the more the front knee is bent at stride foot contact (SFC), the higher a pitcher's velocity. This requires the pitcher to be quick with the hips to get more weight onto the front leg at SFC.
The average bend in the front knee at SFC is 48 degrees for the hardest throwers.
Source: Werner 2008
7. Increase elbow flexion at stride foot contact
The more the throwing elbow is bent at foot strike, the higher the velocity. The average bend in the throwing elbow at stride foot contact is almost 90 degrees for the hardest throwers.

8. Keep the head behind the lead hip longer
Keeping the head behind the lead hip longer (which is why we lead with the front hip with no balance point during the leg kick) also produces less stress on the shoulder.
Source: Werner 2002
9. Don't rush
When a pitcher rushes his delivery, it means the body has moved forward towards the plate too early, causing the arm position to be too low at the time of stride foot contact with the ground and arm acceleration.
This low arm position reduces pitch velocity.
What I have observed in most power pitchers is that the weight is held back over a firm posting leg until the lead leg starts downward. The lead foot comes downward a little more than shoulder width apart and side along the ground to the contact area. The upper body and the head stays at the top center of the widening triangle of the body. The body has only drifted, or fallen forward. There is no major push or drive during this phase.
10. Increase maximum shoulder external rotation
Maximum external rotation (MER) describes the angle at which the forearm "lays back" during the pitching delivery. This is due to a rapid turn of the shoulders as the inertial mass of the baseball pushes the hand and forearm back.
Stressing flexibility, the further the throwing arm rotated back, the higher the velocity because of the increased stored energy (think of a slingshot).
The pitchers who throw the hardest have a maximum external rotation of 160-180 degrees.
11. Increase elbow flexion velocity
Once the throwing arm is cocked, relaxed and ready, the arm must also have good elbow flexion.
This elbow flexion means the ball is inside the elbow, which will allow the arm to move into MER faster because of the shorter arm path due to the increased elbow flexion.
12. Increase upper trunk(torso) and pelvis rotation velocity
Rotation + Extension = Power. This is why it's so important for pitchers to be quick with all movements to the release of the baseball, using trunk rotation to build velocity. The speed and strength of a pitcher's torso is another key element in throwing velocity during the pitching delivery.
In the September 2003 edition of Coaching Management magazine, former White Sox Strength and Conditioning Director Vern Gambetta, acknowledged that the torso plays a key role in getting the arm in the proper throwing position.
In addition to Gambetta, Arnel Aguinaldo, from Children's Hospital San Diego, conducted a study, which proposed that larger body segments create most of the velocity in throwing. Speed of the trunk is not the only aspect of torso that needs to be developed. Late trunk rotation is a movement that can help increase force applied to the ball along with keeping the arm healthy and safe.
Jordana Bieze reported in the June 2004 issue of Biomechanics that collegiate, high school, and youth pitchers rotate less than 15% of their way through the pitching motion. Rotating too early can produce added strain to the arm and shoulder.
Additionally, Stodden and colleagues (2001) studied the effects of the pelvis on velocity and concluded that with a higher pelvic velocity a pitcher could throw harder during his delivery.
13. Increase knee flexion at ball release
Pitchers who throw the ball hardest have their front knee bent to 60 degrees or more at ball release. So their front knees went from 48 degrees bent at stride foot contact to 60 degrees or more at ball release. This is commonly called "bracing up" against a firm front leg.
In 1998, Bruce MacWillams conducted a study that examined ground reaction forces during the pitching motion. The study's results indicated that leg drive is a significant factor in pitcher's throwing velocity. However, the forward motion in the delivery is not the only important action of the lower body. The lead leg that blocks forward movement is also an essential element in a pitcher's throwing velocity...
In a 2001 study, Matsuo found that high velocity throwers were able to plant and extend the lead knee to provide stability to the pitching motion. In addition, the Lexington Clinic was provided an outline evaluating kinetic movements. They included a .89 correlation between throwing velocity and lower body strength.
14. Increase forward trunk tilt at ball release
If you'll notice, the flexing occurs at the hips, NOT the back; the back stays straight through Ball Release.
The researchers felt that extending the front knee at Ball Release (from 48 to 68 degrees) helped increase the forward tilt of the upper body at Ball Release.

15. Thrust your chest at the target during maximum external rotation of shoulder
The kinetic chain from the back leg to the throwing hand in maximum external rotation will demonstrate a reverse "C" position (pictured above).
The latissimus dorsi, given its origin and insertion anatomic position and contraction through the lumbopelvic kinetic chain linkage, generates the greatest force during acceleration and positively increases ball velocity.

16. Increase stride length
90 percent of the pitcher's height, with a goal eventually of reaching 95-100 percent of his height.
The combination provides plenty of momentum to carry him into a long stride length that his 83% of his height (elite pitchers are 75-90%), and maintain force production up the chain.
But still want to land on a flexed front leg
Measuring from the front edge of the rubber to the toe of the stride foot, the length of the stride should be close to the pitcher's standing height.
Aim for as long a stride as possible where the pitcher can still get his head and shoulders over the lead leg at the time of ball release. As the pitcher's foot lands, look to see that he is on the ball of the stride foot, or flat footed. The toes should point slightly in a close position. If the pitcher lands hard on the heel, the foot will usually fly open which causes the hips and trunk to rotate open too soon. It may also cause the pitcher to get onto a stiff front leg too early which causes recoil action, or puts him out of balance and alignment during the accretion phase—both of which negatively affects control and pitch velocity.
Stride faults in direction and length can affect trunk rotation velocity and inclination and contribute to the throwing arm lagging behind the scapular plane and increase stress on the shoulder and elbow.
The late cocking and acceleration phases generate the highest segmental velocities and these phases are implicated in the majority of pitching injuries.
The stride is initiated from the point of maximum lead knee height to the point of foot contact. (Figure 2) Approximately 50% of ball velocity in the pitching motion is the resultant forces accumulated in the stride and trunk rotation.

18. Use a four-seam grip
The best grip for velocity and control on the fastball is across the 4 seams grip. The ball is balanced and consistent finger pressure allows for good control and this grip imparts the fastest ball rotation Generating velocity requires you to apply force to the baseball.

19. Use the wrist
The wrist is a very important lever in the pitching motion. In fact, Norihisa Fujii from the University of Tsukuba concluded after a 2002 study that wrist flexion and strength are major contributors for increasing throwing velocity. In addition, many pitching coaches have incorporated a "wrist flick" during their throwing warm up progression. The Lexington Clinic reported that the wrist accounted for 10% of the force applied to the baseball during the pitching delivery.
Force is not the only function the wrist may perform. Many pitching instructors agree that proper wrist movement can help a pitcher's control and command of pitches to their target.

20. Use the forearm
The forearm is vital to achieve high velocity in the pitching delivery. In Will Carroll's 2004 book Saving the Pitcher; he discussed the use of the forearm in the pitching motion.
During the acceleration stage, the pitcher's forearm will pronate, giving the ball its last bit of energy. Dr. Joshua Dubin explained in his #13 Injury Management Update on Pitcher's Elbow, how a flexed wrist will activate the forearm flexors during the release of the baseball.
Even the most inexperienced pitcher can tell that the forearm lends to force during the pitch. By keeping a hand on the throwing forearm and moving the throwing fingers, a pitcher can feel the movement inside the forearm.
By developing the forearm muscle, pitchers will be able to powerfully pronate their arms during this stage in the delivery.

21. Build leg strength
Leg strength is all important to an efficient weight shift. It's the lower half that initiates movement down the hill and creates energy in the system.
And it's the lower half that puts the brakes on to transfer the created energy up the chain and convert linear momentum into rotational momentum. The more abruptly the brakes are applied, the greater the energy that gets transferred (and that can translate to better velocity and less wear and tear on the arm).
The more efficient this is, the less other parts of the body need to be recruited.
Leg strength also figures into stamina. Over the course of a game, a pitcher's lower half starts and then brakes over and over again.
Start–brake. Start–brake. Start–brake.
Maintaining tempo to put a consistent amount of energy into the system and consistently putting on the brakes to transfer a consistent amount of energy up the chain all help to create a consistent, repeatable delivery. But without stamina, all of this deteriorates as the game goes on. I also agree strong legs provide a stable base to help maintain posture and balance.
So, to me, leg strength doesn't just relate to one or two things - it figures into a lot of things that all can contribute to better performance and health.
22. Build rotator cuff strength
Underdeveloped musculature in the rotator cuff may lead to difficulty controlling throwing-arm deceleration, causing an increase in horizontal adduction across the torso. J Pediatr Orthop. 2008 Jun;28(4):452-9. doi: 10.1097/BPO.0b013e31816d7258. A biomechanical analysis of youth pitching mechanics. Keeley DW1, Hackett T, Keirns M, Sabick MB, Torry MR. Deceleration (Follow Through)‐Demonstrates maximal dominant shoulder internal rotation and 35° of horizontal adduction. Gary J. Calabrese. Int J Sports Phys Ther. 2013 October;8(5):652-660
The rotator cuff is a key contributor to the overhand throw. Pitchers must maintain a strong and healthy rotator cuff if they want to be successful on the mound. In fact, in an outline of kinetic movements by the Lexington Clinic, they found that the shoulder is responsible for 21% of the force placed on the ball. If a pitcher can strengthen this muscle, it is easy to see how pitch velocity can be added.
A University of Hawaii review of literature can back up this claim. It was reported that Toyoshima conducted a study and concluded that 53.1% of an overhand throw velocity was due to the action of the arm. In another 2001 study by Galloway and Koshland, their worked focused on finding a pattern in shoulder or elbow centered activities.
Their findings suggested that shoulder-centered activities were illustrated with straight or curved finger paths. Since the pitching motion requires straight and curved finger action, strengthening the shoulder and corresponding tendons should provide optimal velocity results.

Pitching velocity training
Lastly, when it comes to improving baseball pitching velocity I want you to remember this:
The biggest cause of failure is NOT whether you long-toss or only throw from a mound or use weighted baseballs or strength train or ice your arm after you pitch or listen to some guru or use some velocity program or whatever else the internet would have you believe is a determining factor in building velocity...
...the biggest cause of failure — is quitting.
It's a constant process; never stop improving, never stop learning, and never stop working hard.
