What Is The Average Pitch Speed By Age [Comprehensive Guide]

Pitching speed frequently comes up when discussing baseball and the players’ abilities. High-speed baseball throwing challenges batters and often improves a pitcher’s chances of victory. Knowing the pitch speeds by age can help us understand how an athlete develops over time in this sport.

Average pitch speeds are significantly correlated with experience, physical prowess, and growth when age groups are analyzed. This article will give you a general understanding of average pitch speed by age.

How Fast Should You Pitch By Age?

Many pitchers strive for high velocity, but college and MLB scouts pay considerable attention to a pitcher’s fastball velocity. Little League-age coaches emphasize a pitcher’s ability to throw a hard and fastball.

The strongest predictors of pitch velocity are age, height, shoulder-hip distance, and stride length. Additionally, because of their increased strength and conditioning, young athletes frequently experience pitch speed increases as they mature.

Additionally, hip and t-spine strength gives you an adequate trunk lean and stride speed. There is no practical amount of any of these mechanical traits, but regardless of age, with the appropriate mobility, these mechanics can perform.

Average Pitch Speed By Age Baseball

Baseball players in youth leagues often throw at slower speeds than their counterparts in high school, college, and the professional ranks. Let’s see them in detail:

Youth League Player

Compared to the maximum perceived velocity of high school, college, and professional athletes, the average pitching velocity in youth leagues is substantially slower. Players who fall within this category are often between 9 and 12.

In juvenile leagues, younger players typically throw the ball at an average speed of 40 to 50 mph. Their perceived velocity rises as they advance in the Majors division, with fastballs reaching the maximum level of 50 to 60 miles per hour.

High School League Player

My observations with a group of high school baseball players revealed a noticeable increase in the average pitch speed and the top speed attained.

First-year students between 14 and 15 typically throw balls at average speeds between 65 and 75 mph. As was previously indicated, their perceived velocity increases as they age and become stronger.

The average speed of sophomores between the ages of 15 and 16 is 70 to 80 mph. Some high school pitchers often throw balls up to 84 mph! But you must exercise caution since pitches faster than 80 to 85 mph may result in injury if not used per the pitching workouts.

College Leagues Players

The maximum pitching speed you see by many college league players is between 85 and 95 mph. But remember that not all college athletes have the same maximal speed or perceived velocity. The average pitch speed for those from Division III may be between 77 and 82 mph.

It demonstrates a wide range of abilities, both in terms of top speed and average pitch speed, even at the collegiate level. These outstanding stats show how hard these teams train to raise their game.

Professional League Players

MLB players have the fastest average pitch velocity in all of baseball. They are capable of throwing more quickly than 90 mph. They are highly skilled sportsmen with sophisticated abilities and physical conditioning.

It enables them to reach amazing average pitch speeds, so it’s no surprise this is the case. The MLB players’ average baseball pitch speed km/h is 92-93 mph, faster than any other league.

Pitch Types: Average Throwing Speed by Age

It’s important to remember that these numbers only reflect average pitch speeds and can vary. All athletes, especially pitchers, can develop at different speeds and have specialized skills that affect how quickly they throw the ball. So, pitch size also makes a difference. Let’s take a look at them:


Baseball players frequently use the fastball as a pitch. It delivers with the highest possible velocity to slow down the batter’s reflexes. The typical fastball velocity for various age groups is as follows:

  • Age 8 to 10: Speed is 40 to 50 mph
  • Age 11 to 12: Speed is 50 to 60 mph
  • Age 13 to 14: Speed is 60-70 mph
  • Age 15 to 16:  Speed is 70 to 80 mph
  • High school: Speed is 75 to 85 mph
  • College/professional: Speed is 85 to 95+ mph

The four-seam, two-seam, and cutter are examples of fastball variations.


Curveballs are breaking balls that go downhill and away from the batter. It is thrown with a confident grip and wrist movement to produce a spin that breaks the ball. Following are typical curveball speeds with age:

  • Age 11 to 12: Speed is 45 to 55 mph
  • Age 13 to 14: Speed is 55 to 65 mph
  • Age 15 to 16:  Speed is 65 to 75 mph
  • High school: Speed is 70 to 80 mph
  • College/professional: Speed is 75 to 85 mph


Another breaking pitch is the slider, which breaks later and is sharper than a curve. It is similar to a fastball in arm speed but with a different grip and wrist motion. By age, the average pitching speed for age for a slider is:

  • Age 13 to 14: Speed is 55 to 65 mph
  • Age 15 to 16:  Speed is 65 to 75 mph
  • High school: Speed is 70 to 80 mph
  • College/professional: Speed is 80-90 mph


A changeup is an off-speed pitch that imitates a fastball but travels slower to trick the batter. It reduces velocity while keeping the arm speed constant, changing the grip and throwing action. The average pitch speed by age chart for changeup includes:

  • Age 11 to 12: Speed is 40–50 mph
  • Age 13 to 14: Speed is 50–60 mph
  • Age 15 to 16:  Speed is 60–70 mph
  • High school: Speed is 65 to 75 mph
  • College/professional: Speed is 75 to 85 mph

Average Pitch Speed By Age Softball

Here is the list of Average Pitching Speeds by age:

  • Age 10: Speed is 35 to 39 Mph         
  • Age 11: Speed is 38 to 42 Mph         
  • Age 12: Speed is 41 to 48 Mph         
  • Age13: Speed is 45 to 53 Mph          
  • Age14: Speed is 46 to 54 Mph          
  • Age15: Speed is 49 to 54 Mph          
  • Age16: Speed is 51 to 55 Mph          
  • Age17: Speed is 52 to 56 Mph
  • Age 18: Speed is 55 to 59 Mph         
  • College: Speed is 58 to 65 Mph
