How Hard Does the Average 14-Year-Old Throw?
Around 70 mph, right as the jump to high school arrives. This is the age the foundation you have built starts to show.
The quick take
- The average 14-year-old pitcher throws roughly 70 mph, with about 75 being outstanding for the age.
- Fourteen lines up with the move toward high school and bigger fields, which raises the stakes on mechanics.
- Velocity gains start to taper compared with the big 12-to-13 jump, so development gets more deliberate.
- Showcases begin to appear at 14, and protecting the arm matters more than chasing a radar-gun reading.
The short answer
~70 mph
The average fastball for a 14-year-old (14U) pitcher. Around 75 mph is considered outstanding for the age, and the typical range runs roughly 65 to 75.[1]
Fourteen is a transition year. Many players are moving to the bigger field and into high school programs, where the average freshman sits right around this same 70 mph mark.[1] The huge growth-driven jumps of 12 to 13 start to taper, and the gains from here become more about strength, mechanics, and deliberate development.
Why mechanics start to matter more
As velocity climbs into the 70s, the load on the arm climbs with it. That makes this the age where clean, efficient mechanics stop being a nice-to-have and start being a durability issue. A 14-year-old throwing 72 with an arm-dominant delivery is putting far more stress on the elbow than one throwing the same speed with the whole body. If you have never checked, this is a good age to see whether the mechanics are safe.
Showcases and the radar-gun trap
What matters more than the number
At 14, the job is to build a durable, repeatable delivery and keep the arm healthy as the workload grows. Stay inside pitch-count limits, take a real off-season, and build velocity through strength and sequencing rather than through showcases and weighted balls. The velocity you can still be throwing at 18 is the only number that ends up mattering.
Common questions
How hard does the average 14-year-old throw?+
About 70 mph, with a typical range of roughly 65 to 75. Around 75 mph is outstanding for the age. This lines up closely with the average high school freshman.
What is a good pitching speed for a 14-year-old?+
Anything in the upper 60s to mid 70s is typical, and 75-plus is excellent for the age. As always, size and maturity drive much of the difference, so being below average is common and often temporary.
Should a 14-year-old do showcases?+
There is rarely a reason to chase showcase velocity at 14. College recruiting is still years off, and max-effort showcase throwing adds injury risk without a real payoff at this age. Focus on health and development.
