What Is the Average Baseball Pitching Speed by Age and How to Improve It?

Watching a young pitcher light up the mound can be an exhilarating experience. Whether it’s the thunderous smack of the ball in the catcher’s mitt or the subtle shake of a batter adjusting to the pitch, speed plays a significant role in the excitement of baseball. If you’ve ever wondered how fast a pitcher should be throwing at a particular age or what steps they can take to improve their velocity, you’re not alone.

As a local sports hub, we at Concord Sports have seen countless athletes refine their skills with the right tools and coaching. Whether it’s through custom training programs or the latest in baseball equipment, we’re here to support every step of the journey.

Let’s break down pitching speeds by age and offer some practical tips to help pitchers of all levels reach their full potential.

Average Pitching Speeds by Age

Ages 8–10: Building the Foundation

In this age group, kids are just beginning to understand the mechanics of pitching. The average speed for a youth pitcher is typically around 40–50 mph. While velocity is not the primary focus at this stage, proper form and arm health are crucial. These foundational years set the stage for long-term development.

Ages 11–12: The Pre-Teen Jump

As players grow stronger and more coordinated, pitching speeds tend to increase to 50–60 mph. This is also the age when many young athletes begin experimenting with different pitches, like a changeup or a basic curveball, which can complement their fastball.

Ages 13–14: Transition to the Big Diamond

Moving to a regulation-size field is a significant adjustment, and pitchers between 13 and 14 often throw between 60–70 mph. Strength and conditioning start to play a bigger role, and those who prioritize arm care often see better results.

Ages 15–16: The High School Breakout

By the time players hit high school, average speeds can range from 70–80 mph, with standout athletes often hitting the mid-80s. This age is pivotal for development, as scouts and coaches begin taking notice of a player’s potential.

Ages 17–18: College and Pro Aspirations

For older high school players aiming to play at the collegiate level, velocities between 80–90 mph are common. Exceptional pitchers might even touch 95 mph. At this stage, the gap between recreational players and elite athletes becomes more pronounced, often due to differences in strength training, mechanics, and dedication.

College and Beyond

At the collegiate and professional levels, speeds vary depending on position and role. Starting pitchers often throw between 85–95 mph, while relief pitchers and closers can exceed 100 mph. Velocity isn’t everything at this stage; accuracy, movement, and pitch variety become equally important.

What Influences Pitching Speed?

Physical Maturity

Height, weight, and overall physical development are natural factors that impact velocity.

A growth spurt can lead to a sudden increase in speed, but it’s essential to adjust mechanics accordingly to prevent injuries.

Mechanics and Technique

Efficient mechanics are a cornerstone of high-velocity pitching. Proper body alignment, a strong follow-through, and a consistent release point all contribute to a pitcher’s success. Flawed mechanics can not only limit speed but also increase the risk of arm injuries.

Strength and Conditioning

Strengthening the lower body, core, and shoulder muscles is essential for generating power. A well-rounded conditioning program can help pitchers add velocity safely while maintaining arm health.

Practice and Repetition

There’s no substitute for consistent practice. Repetition builds muscle memory, allowing pitchers to focus on refining their speed without sacrificing accuracy or control.

How to Improve Pitching Speed

Prioritize Arm Care

Arm injuries can sideline even the most promising pitchers. Always warm up thoroughly before throwing, and incorporate recovery routines like icing and stretching post-game. Limiting pitch counts, especially in younger players, helps preserve long-term arm health.

Strength Training

Power starts from the ground up. Squats, lunges, and plyometric exercises build the leg strength needed for an explosive push off the mound. Core exercises like planks and medicine ball throws improve rotational power, a critical component of pitching.

Master the Basics

Young pitchers should focus on perfecting their grip, stance, and delivery. Even small adjustments—like how the ball is held or how weight is distributed during the wind-up—can make a significant difference.

Incorporate Weighted Ball Training

For more experienced players, weighted ball exercises can help develop arm speed and strength. This training method should be supervised by a knowledgeable coach to ensure proper technique and avoid overuse injuries.

Work with a Pitching Coach

A qualified coach can identify inefficiencies in mechanics and provide personalized guidance. Sometimes, having a fresh set of eyes is all it takes to unlock a few extra miles per hour.

Use Video Analysis

Recording and reviewing pitching sessions can reveal subtle flaws that might otherwise go unnoticed. This visual feedback is a game-changer for pitchers aiming to refine their delivery.

Stay Consistent

Consistency beats intensity when it comes to pitching development. A steady practice schedule, combined with incremental progress, leads to sustainable results.

Common Mistakes to Avoid

Overthrowing

Chasing velocity too aggressively can lead to poor mechanics and injuries. Remember, a controlled 85 mph pitch with good movement is far more effective than a wild 90 mph fastball.

Neglecting Recovery

Pitchers who skip recovery routines are more prone to fatigue and injury. Recovery is just as important as the training itself.

Ignoring Flexibility

A stiff body can’t generate the whip-like motion needed for high-speed pitching. Stretching and mobility exercises should be a regular part of any pitcher’s routine.

Focusing Only on Speed

Speed is important, but accuracy and pitch variety are what separate good pitchers from great ones. Don’t neglect the other aspects of the game.

The Mental Side of Pitching

Beyond physical skills, the mental approach to pitching plays a crucial role. Confidence on the mound can directly impact velocity and performance. Visualization techniques, breathing exercises, and maintaining a positive mindset help pitchers stay composed under pressure.

Pitchers who embrace failure as part of the learning process tend to recover quicker from setbacks and grow stronger in the long run. Baseball is a game of adjustments, and mental resilience is key to long-term success.

Final Thoughts on Pitching Development

Improving pitching speed is a journey that requires patience, dedication, and the right approach. Each age group brings its own challenges and opportunities, but with a solid foundation and consistent effort, pitchers can achieve their goals while staying healthy.

Whether you’re a parent of a budding Little Leaguer or a high school athlete aiming for the next level, understanding the progression of pitching speeds and how to improve them can make all the difference. By focusing on mechanics, strength training, and arm care, pitchers of all ages can maximize their potential and enjoy the game they love.
