Exit velocity measures how hard a batter hits the ball, in miles per hour. It’s the most fundamental Statcast metric — everything else builds on it. The harder you hit the ball, the more likely it becomes a hit, an extra-base hit, or a home run.

Average exit velocity across MLB is around 88 mph. The hardest-hitting players regularly average 93+ mph, meaning even their routine contact is more likely to find holes. The elite tier hits the ball so hard that even well-positioned fielders can’t react in time.

Exit velocity is one of the most stable hitting metrics from year to year. A player’s ability to hit the ball hard is a core physical skill that doesn’t fluctuate much. That’s why scouts and analysts treat it as a foundational indicator of offensive talent. On Baseball Nut, you can see batted-ball data on the Zones tab of every player page.

What is a good EV?

Exit velocity is the raw ingredient that powers xBA, xSLG, and xwOBA — which in turn power xNUT. Harder contact produces better expected outcomes, so high-EV hitters tend to have strong NUT Scores.
