Fastpitch vs. Slowpitch Softball - Fastpitch Gear

What's the Difference Between Fastpitch and Slowpitch Softball?

Both fastpitch and slowpitch softball are popular games in the United States. However, there are some significant differences between the two games. If you're new to softball or have only played one form your whole life, this look at slowpitch vs. fastpitch softball will give you the full picture of each.

Differences in Rules & Playing Style

While the fundamentals are the same, there are several key differences for each softball form - the first of which relates to the name itself.

Softball Pitching Style

Fastpitch softball pitchers use a full-windmill motion that produces a much quicker pitch hurled in a straight line. Slowpitch requires a half-windmill pitch thrown with an arc between 6 and 12 feet high - it's really more of a toss. (There's also "modified pitch" softball where the pitcher cannot raise their arm above their shoulder.)

The pitching speed has a significant effect on how the game is played. In fastpitch softball, the pitcher's objective is to prevent batters from putting the ball in play. This puts the pressure on the offense. With slowpitch softball, it's expected that hitters will make contact. As such, the pressure shifts to the defense.

Who Plays Fastpitch and Slowpitch Softball?

Fastpitch softball is what you see at the Olympics as well as at the high school and collegiate levels. It's almost entirely played by women and is considered the more "serious" form. Slowpitch softball is primarily a recreational game played by both men and women.

What are Some Other Rules Differences?

• Fastpitch softball has nine players to a side with nine-inning games. Slowpitch softball has 10 players per side (typically a fourth outfielder) and seven-inning games.
• Bunting, base-stealing and designated hitters are not allowed in slowpitch softball.
• The Mercy Rule in slowpitch allows a game to be called if a team has a 15-run lead after 4 or 5 innings. In fastpitch, the Mercy Rule requires an 8-run lead after 5 innings.

Softball Equipment

With the distinct softball playing styles and rules, it's no surprise the equipment for each game can vary. Here's a look at some of the key differences.

• Softballs: Fastpitch softball typically uses a ball that is 11 inches in diameter and fairly hard, which gives the pitcher more control. Slowpitch uses a softer 12-inch ball that makes it slightly harder to throw, helping slow the game's pace. (There is some overlap in size depending on the player age and sanctioning organization.)
• Bats: Fastpitch softball bats are a little lighter in relation to the length than slowpitch bats. This increases bat speed and control for hitting the faster pitches. Wooden bats are allowed in slowpitch, but not in fastpitch due to the higher risk of breaking and splintering.
• Gloves: Fastpitch softball gloves have a shallower web than slowpitch gloves. Since there are more flyballs in slowpitch, the deeper web allows more leeway when catching the ball. Mitts for catchers and first basemen are also less important in slowpitch.
• Catchers: Fastpitch requires the catcher to wear full head-to-toe gear, including a mask, chest protector and shin guards. Slowpitch only requires the mask.
