Pitch Speed
Pitch speed in slow-pitch softball is how fast the ball travels from the pitcher to the plate, usually 25–35 mph. Many leagues impose a maximum speed limit to maintain the recreational character of the game.
Because slow pitch is designed for recreational participation, maximum speed limits (often 35 mph at the plate or off the pitcher's hand) prevent experienced pitchers from dominating casual leagues. Within the legal speed window, pitchers still vary pace to disrupt timing. A 25 mph pitch after a 33 mph pitch changes the descent angle and arrival time. Hitters who think only about the arc and not the speed arrive late or lunge forward on a slower offering.
Throw your first few pitches at 60-70% effort to build arc consistency before experimenting with speed variation — consistency always beats velocity in slow pitch.
Develop two distinct release tempos — one at full speed and one 15-20% slower — that look identical until the ball leaves your hand. This keeps experienced hitters from reading speed tells early.
Example
A pitcher throws at 28 mph, then drops one to 22 mph with the same arm motion. The batter lunges out front and pops it up.
How it shows up on video
Compare the ball's travel distance in equal time intervals at the start and end of its flight — significant deceleration beyond 40% of initial speed suggests a very low-speed pitch. Watch how early the batter begins their stride trigger relative to release, as lunging forward indicates the hitter was fooled by a speed change. A radar gun reading at plate level is the most reliable confirmation of league compliance.
Common mistakes
- Exceeding the league maximum speed limit with an aggressive delivery, risking ejection and illegal-pitch calls that hand the offense free bases
- Using identical pitch speed on every batter, making timing trivially predictable after the first plate appearance of any given at-bat
- Batters ignoring pitch speed variation and timing only to the arc peak, causing them to be reliably late or early on speed changes
- Not checking league-specific speed rules before a tournament, since maximum speeds vary across associations and division levels
In SwingVantage Motion Lab
Motion Lab does not track the ball, so it cannot estimate pitch speed. A radar gun at plate level gives a reliable reading.

- Arc Height RegulationArc height regulation defines the required minimum and maximum height a slow-pitch delivery must reach — usually 6 to 12 feet — to be called a legal pitch.
- Stride TimingStride timing is when the front foot lands during the pitch's arc. In slow pitch, it should land early, near the peak, with the hands back for power.
- Pitch TrackingPitch tracking is following the slow-pitch ball with your eyes from release, through its peak, to contact. It is the key to timing a steeply falling ball.
