How Fast Does a Fastball Travel?

If you have ever participated in a game of baseball, you are aware that pitchers who throw fastballs can deliver them with great speed. Some pitchers attempt to strike out batters by throwing pitches outside of the strike zone.

Others may try to deceive batters by throwing pitches that have movement. However, fastball pitchers simply aim to throw the ball as hard and as fast as they can, hoping to get it past the batter before they can react.

Fastballs are the most commonly thrown type of pitch in baseball. Over time, several different types of fastball pitches have been developed.

When you hold the baseball with your fingers across the wider part of the seam, allowing both your index and middle fingers to touch two seams, you throw a straight pitch known as a “four-seam fastball.” This pitch has minimal movement and is often used when a pitcher needs to throw a strike.

A two-seam fastball, also referred to as a “sinker,” is thrown by gripping the baseball across the narrower part of the seam, with both the index and middle fingers along a seam. Sinkers are more challenging to throw, but the movement they generate can make them more difficult to hit.

A cut fastball, or “cutter,” is thrown using the same grip as a four-seam fastball. However, instead of the usual grip, the pitcher holds the baseball off-center. This pitch deceives batters as it moves slightly as it reaches the plate.

There are some batters who believe in a mythical pitch called a “rising fastball,” where the ball appears to hop as it crosses the plate and misses the bat. However, we can assure you that rising fastballs fall into the same category as unicorns and the Loch Ness Monster.

When pitchers throw fastballs, they apply backspin to the baseball. This scientific phenomenon, known as the “Magnus effect,” creates an upward force on the baseball, causing it to fall slower than expected.

However, gravity ultimately prevails, and fastballs do indeed fall from the moment they leave the pitcher’s hand until they reach the catcher’s mitt.

Why do many batters believe that fastballs can actually rise? Scientists believe it is an optical illusion.

If a pitcher switches from throwing a two-seam fastball to a four-seam fastball, the batter expects a slower pitch. When the baseball arrives faster at a higher level (due to the increased backspin when thrown faster), it appears to rise.

Scientists would argue that the Magnus effect can defy gravity, making a rising fastball theoretically possible. However, these same scientists have demonstrated that the amount of backspin required is beyond the capabilities of the human arm.

So, how fast does a fastball travel? There is no set speed that defines a fastball. It is simply a type of pitch that results from a pitcher throwing the baseball as hard and as fast as they can.

For many years, the top baseball pitchers in the major leagues aimed to reach the 100 miles per hour (mph) mark for a fastball. At one point, Nolan Ryan held the world record with a 100.9 mph fastball thrown in 1974. Nowadays, it is quite common for major league pitchers to routinely throw fastballs in the range of 95+ mph.

Due to technological limitations and the accuracy of measuring pitch speed, determining who has thrown the fastest fastball ever remains a topic of intense debate among baseball enthusiasts.

In September 2010, Aroldis Chapman, a pitcher for the Cincinnati Reds, threw a fastball that was measured at a speed of 105.1 mph. Unofficially, Bob Feller claimed that back in 1946, he threw a fastball that was measured at a speed of 107.9 mph. Over the past decade, there have been at least 20 different pitchers who have thrown fastballs that were measured at speeds over 101 mph.

Now let’s try out some baseball activities. Grab a friend or family member and try the following:

1. Test your Fastball Reaction Time online to see if you can hit a fastball. This fun game will measure your reflexes and determine if you’re fast enough to hit a real fastball. Challenge your friends to play against you.

2. If you want some real on-field time, gather your baseball equipment and head to the field with some friends or family members. There’s nothing quite like playing an informal game of baseball with your loved ones. Take the opportunity to work on different pitches, including your fastball.

3. If you want to improve your pitching skills, you can learn How to Grip and Throw Different Baseball Pitches online. See how many different pitches you can learn to throw. If possible, find someone who plays or has played baseball to help you with your practice.
