Baseball Pitching Speed by Age: Average Velocity From 8U to MLB, Plus Fastpitch (2026 Chart)

Quick answer: a typical 8U pitcher throws about 35 to 43 mph, a 10U about 41 to 52, a 12U about 47 to 60, a 13U about 52 to 65, a 14U about 57 to 70, and varsity high school pitchers commonly sit 75 to 85 mph. College arms mostly live at 80 to 90, and the MLB fastball averages around 94. In fastpitch softball, a typical 12U pitcher throws about 40 to 50 mph, a 14U about 45 to 55, a 16U or 18U about 50 to 60, and college pitchers about 60 to 70. Those are fair ranges, not cutoffs. At any 12U tournament you will see one kid throwing 45 and another throwing 65, and both can be exactly on track.

We build MAVTRAX, the free pitch-calling app coaches run from the dugout, so we spend our weekends around backstops where somebody is always pointing a radar gun. This page is the reference we wish existed. It covers velocity by age for baseball and fastpitch, what "fast" actually means at each level, how the numbers interact with mound distance, how much gain per year is realistic, how to measure your own pitcher without fooling yourself, and the arm-care red flags that matter more than any number.

These ranges blend what radar-gun makers, training academies and showcase events commonly report. The "fast for the age" column is roughly the top 10 to 20 percent of tournament pitchers, not a record book.

Two caveats. First, puberty timing dominates. An early-developing 12U can outthrow a late-developing 14U, and both can end up in the same place at 17. Second, published charts disagree with each other by several mph because nobody radars a random sample of all kids. Showcase and travel data skew fast. Treat every number here as a range with soft edges, and check your league's current rulebook for the exact mound distance your pitcher throws from.

Fastpitch is its own sport on the radar: the ball is bigger, the delivery is underhand and the circle is much closer, so the numbers run lower than baseball but play just as fast. Typical ranges, blended the same way as the baseball chart:

Because the circle is 40 to 43 feet away, fastpitch reaction times are brutal. A 60 mph pitch from 43 feet reaches the plate in about the time an 84 mph baseball takes from 60 feet 6 inches, and a 70 mph college riseball plays like a high-90s fastball. Distances vary by organization, so confirm yours in the distance by age chart and your league's rulebook. Every radar that reads baseball reads fastpitch; see our radar gun rankings for the options.

Parents usually search for one age, not a chart, so here is the same data as short notes.

• 8 years old: about 35 to 43 mph. Many 8U leagues are still coach or machine pitch. The goal is a repeatable motion and throwing strikes, and velocity is a byproduct of growth.
• 9 to 10 years old: about 41 to 52 mph from 46 feet. A 10-year-old at 55 is throwing hard for the age. At 10U, throwing strikes and staying inside pitch limits matters far more than the radar.
• 11 to 12 years old: about 47 to 60 mph, with the hardest throwers in a tournament in the 60s and a rare few near 70. From 46 feet, 60 mph plays like about 79 at the big-league distance, which is why 12U aces feel unhittable.
• 13 years old: about 52 to 65 mph. This is the transition year to a 50 to 54 foot mound, so every pitcher plays slower than his reading, and many see a dip in results even while the radar climbs.
• 14 years old: about 57 to 70 mph, with growth spurts creating the widest spread of any age. Some 14-year-olds are still in the 50s, others touch the mid 70s.
• 15 to 16 years old: about 65 to 77 mph for JV and underclass pitchers. Structured strength work starts to show up here.
• 17 to 18 years old: about 75 to 85 mph for varsity starters. Pitchers in the upper 80s draw college interest, and low 90s draws a lot of it.

For what those pitchers should actually be throwing (fastball, changeup, when a breaking ball is reasonable), pair this with pitch types by age.

Velocity comparisons across ages only work if you remember the mound moves. Through 12U most leagues pitch from 46 feet, 13U moves to 50 to 54, and high school is 60 feet 6 inches. The hitter experiences time to the plate, not mph, so the same radar reading plays completely differently by level:

That is why a 12U ace feels unhittable and why the first year on the big field humbles everyone: the hitter's reaction time grows by about 30 percent and the "feels like" bonus disappears. (The math above is simplified. It ignores the release point being a few feet in front of the rubber and the ball slowing on the way in, but the comparison holds.) The full distance ladder by league lives in our pitching distance by age chart.

During the growth years, a few mph per year is a normal climb, and a season with no gain at all is common and nothing to panic about. Velocity tracks physical maturity more than anything else, so the biggest jumps usually come during and after the growth spurt, typically somewhere between 13 and 16 for boys. Before that, gains come mostly from getting bigger and repeating a delivery. After it, they come from strength, mobility and mechanics.

Three rules keep expectations sane:

1. Compare a pitcher to himself. Last spring's number, same gun, same setup, is the only benchmark that matters. Comparing him to the tallest kid on the travel team tells you about puberty, not pitching.
2. Measure twice a season, not twice a practice. Spring and late summer readings show the trend. Kids radared every bullpen start overthrowing for the gun, and their mechanics unravel.
3. Plateaus are normal. Long plateaus followed by sudden jumps are the typical pattern, especially around growth spurts. A flat year is not a failed year.

Be skeptical of any program that promises a guaranteed number of mph in a set number of weeks for a youth pitcher. Real gains for young arms are slow, and velocity borrowed through max-effort throwing on an immature arm has to be paid back.

Most families never get a real number, because stadium-style guns look expensive and phone apps look free. The middle path is a real radar, used correctly:

1. Use a real radar device. The Pocket Radar Ball Coach (about $299) is the youth-baseball standard, and the Smart Coach (about $399) adds app logging and video with the speed embedded, so you can track a season. The Bushnell Velocity (about $150) is the cheapest real radar from a known brand. A hands-free budget unit like the NET PLAYZ (about $65) is fine for ballpark numbers. Our best baseball radar guns page ranks every format and price.
2. Stand directly behind the catcher or pitcher. Radar reads only the part of the ball's speed moving toward the gun. From 20 degrees off the line it reads about 6 percent low, which is 4 mph off a 70 mph pitch. The physics are in are Pocket Radars accurate?
3. Warm up fully, then clock 10 or more pitches and take the best 3 to 5. One reading is noise. Fatigue, grip and effort swing individual pitches.
4. Log the distance and the gun with the number. "58 at 46 feet on the Ball Coach" and "58 at 60 feet 6 inches on a stadium gun" are different pitchers. Write all three down every time.
5. Skip the phone app for anything that matters. Radar gun apps estimate from video frames and a typed-in distance, and they can drift by several mph on the same pitch. See radar gun app vs. a real radar gun.

Most disagreements come from angle, from release speed versus plate speed, or from a budget gun, not from the kid. A pitch is fastest as it leaves the hand and slows by several mph on the way to the plate. Pocket Radar and most consumer radars report peak (release) speed. A gun that reports speed nearer the plate will read lower for the same pitch.

Angle is the other big one. Showcase guns sit dead behind the plate, while parents often hold theirs from beside the backstop, which reads low. And sub-$100 units can wobble a couple of mph either way. If you want your home number to match event numbers, use a serious-tier radar directly behind the catcher, and always compare like with like. Want to know which radar to trust? The answer is in Smart Coach vs. Ball Coach and our Pocket Radar guide.

The uncomfortable truth behind every velocity chart is that the biggest driver is growth, and no training plan moves puberty. Here is what families can control:

• Through 10U: athleticism, not velocity programs. Play multiple sports, throw on a loose schedule and keep basic mechanics clean. A kid who can repeat a delivery gains velocity automatically as he grows.
• 11U to 13U: strike-throwing and a changeup. This is the window where command plus a real changeup wins more games than 5 extra mph. It is also where coach-called games teach pitch sequencing. Long toss builds arm strength without max-effort mound work.
• 14U and up: structured strength work pays. Once the growth spurt is underway, lower-half strength, mobility and a monitored throwing program produce real gains. This is also when weighted-ball programs become a conversation, and they belong under a qualified coach, not a video-sharing-site plan.
• Every age: workload is the ceiling. Velocity gained on a tired arm is borrowed, not earned. The pitch count and rest rules are the floor, not a suggestion.

For practice at home, a portable mound set at your game distance and a net make every bullpen count. Train at the distance you pitch from in games.

A radar is an arm-care tool as much as a bragging tool: a pitcher whose velocity drops noticeably inside an outing, or from one week to the next without explanation, is often telling you his arm is tired or hurt. Coaches who gun games often pull a pitcher when his fastball falls several mph below where he started, even if he is under his pitch limit. Here are the red flags that should end the day, not just the inning:

• Any pain in the elbow (especially the inside of the elbow) or the shoulder while throwing, or pain that lingers after. Soreness in the muscles is one thing. Joint pain is a stop sign and a reason to see a sports medicine professional.
• A sudden velocity drop within an outing, or from one session to the next, with no other explanation.
• Lost command late in an outing, a dropping arm slot, or a pitcher "shaking out" his arm between pitches.
• Pitching on consecutive days, or pitching and catching in the same game. USA Baseball and MLB's Pitch Smart guidelines advise against both.
• No offseason. Pitch Smart recommends several months off from competitive pitching each year, including a stretch of consecutive months, and limits on total innings in a calendar year. Check the current guidelines for the exact numbers for your pitcher's age.
• Showcase stacking: multiple max-effort radar sessions or events in a short window, especially early in the year before the arm is built up.

None of these rules is about velocity, and all of them decide whether a pitcher gets to keep throwing long enough to develop it. Pair the radar with a pitch counter, and read pitch count rules by age before the season starts.

Through 12U, strikes win; from 13U on, velocity starts to matter, but only with command attached. A 12U pitcher at 52 mph who throws two pitches for strikes will beat a 60 mph pitcher who walks the bases loaded, nearly every time. At the high school level, 80 mph with location and a changeup gets outs, while 85 mph straight down the middle gets hit.

The best development plan uses velocity as a long-term measurement and command as the daily focus. Call games to locations, chart where pitches actually go, and let the radar tell you about growth twice a season. For the location side, pitch locations explained covers the zone numbering coaches use to call pitches. Coaches who call pitches from the dugout can send the call straight to the catcher's helmet with the free MAVTRAX pitch-calling app.
