Exit velocity climbs fast through the growth years, then flattens as hitters reach their strength ceiling. Knowing the typical number for an age keeps expectations honest — a 10-year-old at 48 mph and a college hitter at 48 mph are two very different stories.
These are approximate averages for solid contact — a clean barrel hit off a tee or a machine, not a mishit and not a once-a-session peak. Individual players vary widely, and early or late physical maturity moves a hitter up or down the chart more than age alone.
| Age | Typical average EV | Strong for age |
|---|---|---|
| 8 | 38–42 mph | 48 mph |
| 9 | 42–46 mph | 52 mph |
| 10 | 46–50 mph | 57 mph |
| 11 | 50–55 mph | 62 mph |
| 12 | 54–60 mph | 66 mph |
| 13 | 58–65 mph | 72 mph |
| 14 | 63–72 mph | 80 mph |
| 15 | 68–78 mph | 86 mph |
| 16 | 73–84 mph | 91 mph |
| 17 | 78–88 mph | 95 mph |
| 18 | 82–92 mph | 98 mph |
| College | 88–98 mph | 103 mph |
| Pro / MLB (in-game avg) | 88–90 mph | 115+ mph peak |
Want a real number for one player instead of a range? The Exit Velocity & Distance Predictor compares an exit velocity to the level benchmark and estimates how far that contact carries.
The steepest gains show up in the growth-spurt window. Between roughly 12 and 16, hitters add height, lever length, and fast-twitch strength — all of which raise bat speed, and bat speed is the biggest driver of exit velocity. A player can gain 15–20 mph of exit velocity in two years during this stretch without changing anything about their swing.
That is also why comparing a young hitter to an older one is misleading. Two players with identical mechanics can be 20 mph apart purely because one hit their growth spurt first.
A pocket radar, a swing trainer, or a pitching machine are the three most common tools for exit velocity development work.

A 12U hitter making solid contact typically produces around 50 to 60 mph, with stronger players reaching the mid 60s. Use the session average, not one peak reading.
High school hitters generally range from about 68 to 92 mph. Varsity players headed to college often sit in the mid 80s to low 90s, and anything above 90 mph is a strong, recruitable number.
Average in-game MLB exit velocity is roughly 88 to 90 mph across all batted balls, with elite hitters peaking above 115 mph on their hardest contact.
