# Time to hit a 95 mph fastball

**Time to hit a 95 mph fastball: 375 ms–425 ms**

Physical limit — the time available, not a human figure

The ball is in the air for roughly four tenths of a second, and the swing itself takes about 150 milliseconds and cannot be aborted once started. That leaves something like 150 to 200 milliseconds to identify the pitch and commit — barely one visual reaction time. Batters therefore do not react to the ball; they predict it from the pitcher's arm and release, which is why a pitcher who hides the ball well is effective regardless of speed.

## The numbers

- **Typical:** 400 ms
- **Range:** 375 ms to 425 ms
- **What it is:** Physical limit — the time available, not a human figure
- **What is measured:** Flight time from the pitcher's release to the plate, about 55 feet at 95 mph.

## Why this is a physical limit

This is how long the event gives you, not how long a person takes. It is here because comparing the two is the only way to see whether reacting is possible at all.

## Common questions

### How long is time to hit a 95 mph fastball?

Typically 400 ms, with a real range of 375 ms to 425 ms. Flight time from the pitcher's release to the plate, about 55 feet at 95 mph.

### Is that a reflex or a reaction?

Physical limit — the time available, not a human figure. This is how long the event gives you, not how long a person takes. It is here because comparing the two is the only way to see whether reacting is possible at all.
