What Is Exit Velocity in Baseball?

Exit velocity is the speed of the baseball as it comes off the bat, measured in miles per hour. It is tracked by Statcast on every batted ball. A higher exit velocity means harder contact, and harder contact turns into more hits, more extra-base hits, and more home runs. Any batted ball hit 95 mph or harder is classified as hard-hit.

How exit velocity is measured

Statcast cameras and radar record the speed of the ball the instant it leaves the bat. Each player accumulates an average exit velocity over the season, plus a hard-hit rate, which is the share of their batted balls hit at 95 mph or more. These are among the most stable, predictive numbers in baseball, because how hard a hitter squares the ball up changes slowly.

Why exit velocity matters

Hard contact is the foundation of run production. Two things make it especially useful:

It leads the box score. A hitter can crush the ball for a week and have little to show for it because of bad luck or good defense. High exit velocity flags that the results are likely coming before the batting average catches up.
It pairs with launch angle to make barrels. A barrel is a batted ball with the ideal combination of exit velocity and launch angle. Barrels are the single best predictor of home runs and extra-base hits, and you cannot barrel a ball without high exit velocity.

How to use it for betting

Exit velocity is an early signal. A hitter whose average exit velocity and hard-hit rate are climbing, but whose batting average has not moved yet, is often undervalued in props and home run markets. The market tends to price recent results, while exit velocity prices the quality of contact underneath them.

It is a leading indicator, not a guarantee. A hitter still needs the right launch angle and matchup to turn hard contact into a hit, which is why it works best alongside park, pitcher, and barrel data.

Frequently asked questions

What is a good exit velocity in MLB?

A batted ball of 95 mph or more is hard-hit. Elite hitters average well into the 90s, and the hardest-hit balls reach roughly 120 mph.

What is the difference between exit velocity and a barrel?

Exit velocity is just the speed off the bat. A barrel combines high exit velocity with the ideal launch angle, which is why barrels predict home runs better than exit velocity alone.

Does high exit velocity mean a hitter will get more hits?

Not on every swing, but over time, yes. High exit velocity and hard-hit rate are leading indicators of hits and extra-base hits, even when surface stats lag.

Why do bettors care about exit velocity?

Because it flags quality of contact before results show up, which can reveal undervalued hitters in prop and home run markets.
