You step into the cage at a showcase, crush one off the tee, and the device flashes 83 mph. The coach next to you wants to see 90. Nobody tells you what to actually change. That gap between the number you have and the number you want is where most hitters get stuck. So let’s close it. In this guide you’ll learn exactly what exit velocity in baseball measures, what counts as a good number at your level, and the trainable swing metrics that move it. By the end you’ll stop chasing a radar reading and start training the swing that produces it.
The Short Answer
Exit velocity is the speed of the baseball as it leaves the bat right after contact, measured in miles per hour and tracked at the big-league level by Statcast since 2015.
Here’s the part most pages skip: exit velocity is a result, not a swing input. You don’t “swing exit velocity.” It’s the scoreboard number that shows up after bat speed, contact quality, and timing all do their jobs. That distinction matters, because you can’t train a result directly. You train the inputs that produce it, and the number climbs on its own.
Why Exit Velocity Matters
Two hitters can go 1-for-4 on the day. One squared three balls at 95 mph and got robbed twice. The other bled three softliners that found grass. The box score lies. Exit velocity tells you who actually hit the ball.
A. Harder contact wins more at-bats
The harder you hit the ball, the less time the defense has to react and the more often the ball finds a hole. A 95 mph line drive gives an infielder a fraction of the reaction window a 75 mph roller does. You can’t control where the defense stands, but you can control how hard you make them play.
B. It’s a recruiting and projection number
College and pro evaluators lean on exit velocity because it projects. Evaluators commonly want to see 90+ mph from a high school senior, with elite D1 programs pushing toward 95+, and hitters living above 95 mph put themselves in Division I and pro-scouting conversations. It’s one of the first numbers on a showcase profile for a reason.
C. Average beats peak
One loud swing means little. A single 100 mph blast next to a pile of 78 mph weak contact tells a scout your mechanics aren’t repeatable. Average exit velocity reflects consistency, and consistency is what wins games and gets you seen. Chase a higher floor, not a louder ceiling.
Takeaway: Treat exit velocity as a quality-of-contact scorecard, and prioritize raising your average over spiking your max.
What’s a Good Exit Velocity by Level
Numbers vary by source and setup, but these exit velocity by age benchmarks (measured as max exit velocity) give you an honest map. For a deeper breakdown by age, see Exit Velocity by Age from WIN Reality.
- Youth (8–12): roughly 45–60 mph
- Middle school (13–14): roughly 60–75 mph
- High school JV (15u): roughly 70–80 mph
- High school varsity (16–18u): roughly 85–90 mph
- College: roughly 95–105+ mph, climbing with division level
- MLB: the hardest-hit balls in a season regularly top 115 mph, and the hardest ball ever tracked by Statcast is Oneil Cruz’s 122.9 mph home run on May 25, 2025.
Before you celebrate or panic, read the fine print:
- Tee reads higher than the game. Exit velocity off a tee runs roughly 5–10 mph faster than in live at-bats, because the timing of a real pitch is removed. Compare tee to tee, game to game, never across the two.
- Bat standard changes the number. A USSSA bat will read higher than a USA/ASA bat for the same swing. Part of any “gap” is the bat, not you.
- Progress is gradual. Developing teen hitters commonly add about 3–5 mph per year, with the biggest jumps between 14 and 16. That’s normal. Anyone promising overnight jumps is selling something.
Takeaway: Find your level’s range, measure under consistent conditions, and target a steady 1–4 mph gain per season.
The Swing Metrics That Actually Drive Exit Velocity
Here’s where you get your training plan. Exit velocity is the output. These are the Blast Motion metrics you can measure and move:
- Bat Speed. The engine. More speed at contact means more energy into the ball. If your peak exit velocity is low, bat speed is usually the first lever to pull.
- On-Plane Efficiency (OPE). How well your barrel stays in the hitting zone through contact. Target 70%+ (Blast’s swing data puts the MLB average at 68.6%). Low OPE means you’re squaring balls up by luck, not by design, and your average exit velocity suffers.
- Early Connection. How your body and barrel work together as rotation starts. Aim for around 90° (an 80–105° range). Poor connection leaks power before the barrel ever reaches the ball.
- Rotational Acceleration. The “0–60 time” of your swing, how fast you get the barrel up to speed. High rotational acceleration is what turns raw bat speed into game power.
So how do you know which one to train? Ask the classic hitter’s question: do I need more bat speed, or better contact? A high peak but low average points to contact quality, so chase On-Plane Efficiency and Connection. A low peak across the board points to the engine, so build Bat Speed and Rotational Acceleration.
Takeaway: Diagnose the specific metric holding you back, then train that one on purpose instead of guessing.

Tools and Methods to Measure and Build Exit Velocity
You have three real options for measuring and building the number:
- Radar or exit-velocity devices. These give you a direct EV reading off the tee or in the cage. Useful for a snapshot, but a one-time showcase number tells you what happened, not why, and gives you no path to fix it.
- A bat-mounted swing sensor. This is the input-tracking method. Instead of one reading, you get continuous data on bat speed, on-plane efficiency, connection, and rotational acceleration, so you can train the causes of exit velocity every session. Blast Baseball mounts on the knob of the bat and syncs to your phone.
- Overload/underload and med-ball training. Build the engine with structured strength and speed work. Run the Torque Drill and Med Ball Scoop Toss to develop rotational power, and pair them with cue-driven cage work like the Shoulder Slot Drill and Walk Through Drill. The Hook ‘Em Drill (Driveline Baseball) is another good addition here — it trains an even coil of the pelvis and torso and the timing of hip-shoulder separation, which is exactly the blend of linear and rotational movement this phase is building. A simple cue that ties it together: “slow and early, swing from the center of your body.”
Takeaway: Use a radar reading to benchmark, a swing sensor to diagnose and train the inputs, and drills to build the physical engine.
How Blast Motion Helps
You can’t fix what you can’t see. Blast Baseball turns any bat into a smart training tool. The Gen 3 sensor mounts on the knob and tracks bat speed, attack angle, on-plane efficiency, connection, rotational acceleration, time to contact, and power, then Blast iQ™ scores each swing and flags your focus areas in green, yellow, or red so you know exactly which input to work next. It’s trusted by 300+ college and pro teams and used across 83% of pro organizations.
One honest note: on the baseball side, Blast Baseball measures the swing inputs that correlate to exit velocity rather than the ball’s speed itself. On the softball side, Blast Softball reports Exit Velocity directly among its metrics. Either way, you’re training the swing, not guessing at it.

The Bottom Line
Exit velocity is the scoreboard. Bat speed, on-plane efficiency, and connection are the dials. Stop chasing the number and start training the inputs behind it, and watch the reading climb season over season.
