Using the Pitch Count Tracker
Tracking pitch counts is critical for preventing arm injuries in youth pitchers. The pitch count tracker is a simple counting tool that helps you monitor pitches during a game and stay within safe limits.
Why Track Pitch Counts?
Injury Prevention
Youth pitcher arms are still developing. Overuse is the number one cause of youth pitching injuries. Fatigue leads to poor mechanics and arm stress, and cumulative pitch counts over weeks cause damage. Tracking pitches helps you stay within safe limits and catch fatigue before it leads to injury.
League Compliance
Most youth leagues have pitch count rules: maximum pitches per game by age, required rest days based on count, and sometimes maximum pitches per week. Tracking helps you comply with these rules and avoid forfeits due to violations.
How the Tracker Works
The pitch count tracker is a straightforward counting tool with visual warnings.
Counting Pitches
Increment/decrement buttons: Tap the plus button for each pitch thrown. If you accidentally add one, tap the minus button to correct it. The current count displays prominently so you can see it from a distance.
Pitcher Name
Enter the pitcher's name at the top of the tracker so you have a record of who is pitching.
Inning-by-Inning Tracking
The tracker records pitches by inning. When an inning ends, mark it complete and the tracker starts a new inning count. You can see the pitch breakdown for each inning in the history display below the counter.
Example display:
Inning 1: 14 pitches
Inning 2: 18 pitches
Inning 3: 22 pitches
Current (Inning 4): 11 pitches
Total: 65 pitches
This helps you see which innings the pitcher is working harder and whether fatigue is setting in (rising pitch counts per inning often indicate tiring).
Configurable Limits
Set the limits that match your league's rules:
Max pitches: Default is 75. Change this to match your league's maximum for the pitcher's age group.
Max innings: Default is 6. Set this to match your game length.
Warning Levels
The tracker uses color-coded visual indicators to alert you as the pitcher approaches limits:
Green: Under 75% of the maximum. Pitcher is in a safe zone.
Yellow (caution): At 75% of the maximum. Start warming up your relief pitcher.
Red (danger): At 90% of the maximum. Pitcher should be removed soon.
For example, with a 75-pitch max: yellow warning appears at 56 pitches, red warning at 68 pitches.
Session Persistence
The tracker saves your current session to localStorage, which means it survives a page refresh. If you accidentally close the browser or your phone screen locks, your count is still there when you come back.
Session Reset
When you are done tracking, use the reset button to clear the session and start fresh. The tracker asks for confirmation before resetting to prevent accidental data loss.
Age-Based Pitch Count Guidelines
These are general guidelines based on USA Baseball recommendations. Always check your specific league's rules, as they may differ.
| Age | Recommended Max Pitches/Day |
|---|---|
| 7-8 | 50 |
| 9-10 | 75 |
| 11-12 | 85 |
| 13-14 | 95 |
| 15-16 | 95 |
| 17-18 | 105 |
Rest Day Guidelines
Required rest based on pitches thrown (standard guidelines, may vary by league):
| Pitches Thrown | Rest Required |
|---|---|
| 1-20 | 0 days |
| 21-35 | 1 day |
| 36-50 | 2 days |
| 51-65 | 3 days |
| 66+ | 4 days |
Rest days mean calendar days, not just skipping one game.
Best Practices
Count Every Pitch
Do not estimate or approximate. One missed pitch could be the difference between safe and risky. Have a dedicated person tracking (parent, assistant coach, or scorekeeper) so the head coach can focus on the game.
Track All Pitching Activities
Game pitch counts are most important, but also be aware of bullpen sessions, batting practice pitching, showcase events, and private lessons. Cumulative stress includes all throwing, not just games.
Communicate with Parents
Share pitch count information with parents so they can reinforce rest at home (no backyard throwing during rest periods). Transparency about pitch counts also helps parents understand pitching rotation decisions.
Plan for Tournaments
For weekend tournaments with multiple games:
- Check pitch counts from previous games
- Plan your rotation to spread the workload across 3-4 pitchers
- Do not use the same pitcher on consecutive days if they had a high count
- Use the tracker for each game so you have accurate cumulative totals
Common Scenarios
Pitcher Wants to Keep Throwing
The pitcher is at 65 pitches and begs to stay in. Explain that safety is the priority, show the pitch count on the tracker, and stick to the limit. It is non-negotiable. Protecting a young arm is more important than any single game.
You Forgot to Track a Previous Game
Contact the opposing team's scorekeeper, check with the umpire (some track counts), or review video if available. Estimate conservatively and err on the side of caution. Then make tracking non-negotiable going forward by assigning someone specifically to the job.
League Dispute About Pitch Count
If someone claims your pitcher exceeded the limit, your inning-by-inning tracking data from the tracker serves as your record. This is one of the key reasons to track diligently.
Coming Soon
There are plans to add pitch type tracking, velocity tracking, multi-game analysis, and lineup generator integration in a future update.
Age-Specific Considerations
7-8U (Coach Pitch / Machine Pitch)
At this age, most leagues do not have player pitching. If players do pitch, limits are very low (25-35 pitches). Track carefully and emphasize mechanical development over volume. No breaking balls at this age.
9-12U (Kid Pitch)
This is the critical age for injury prevention. Strictly enforce pitch limits, monitor fatigue carefully, limit breaking balls, and encourage players to play multiple positions rather than pitching exclusively.
Warning signs: Pitching on consecutive days, multiple games per week, velocity dropping during a game.
13-18U (High School Age)
More volume is expected, but protection is still necessary. Players at this age may pitch for multiple teams (school and travel). You need to track all pitching across all teams and coordinate with other coaches. A player's arm does not know which team they are pitching for.
