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.

Typical
400 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.
