The 90 MPH
Fastball... How long does it take to
for a 90 mile per hour fastball to cross home
plate - about a half a second... A batter facing
a 90 mph fastball has less than half a second to
decide whether or not to swing at the pitch.

Here's the math:
There are 5,280 feet in a mile. With 60
minutes in an hour the ball travels
7,920 feet per minute. 60 seconds in a
minute, the ball travels 132 feet per
second.
7,920 feet per minute - (5,280 x 90) /
60
132 feet per second - 7,920 / 60
7,920 = 1.5 miles
Home plate is 60 feet 6 inches from the
pitcher's mound. 60 feet, 6 inches is
60.5 feet. To get the number of seconds
for a ball traveling 90 MPH to travel
60.5 feet, I divided 132 (feet per
second) by 60.5 (distance from pitcher's
mound to home plate). The result is
.458.
What does this mean? A batter facing a
90 mph fastball has less than half a
second to decide whether or not to swing
at the pitch. That's not a lot of time.
Now consider if a pitcher takes 10 mph
off of a pitch, the ball takes .516
seconds to reach the plate. This
explains why a pitcher that can change
speeds gets a lot swings and misses.
Note: Pitchers generally release the
ball closer to home plate than 60 feet,
6 inches. How much closer depends on the
height and release point of the pitcher. |
