Every youth league has a pitch count rule, and every season a coach gets caught by one. The limit itself is easy to remember. The rest-day schedule that comes with it is where games get forfeited and arms get hurt. This guide lays out the MLB and USA Baseball Pitch Smart guidelines that most leagues build their rules on, works through a real example, and shows how to track counts so you never have to do the math in the dugout.
Why Youth Pitchers Have Pitch Counts
Young arms are still growing, and throwing is the most stressful thing a baseball player does. Pitch counts exist to put a ceiling on that stress in a single day and to force recovery time between outings. The guidelines used across youth baseball come from Pitch Smart, a joint program from Major League Baseball and USA Baseball, and they cover ages 7 through 22.
Two numbers matter for every age group. The daily maximum is the most pitches a player may throw in one day. The rest-day schedule says how many calendar days the player must sit out based on how many pitches they threw. Leagues adopt these numbers as written or with small changes, so the Pitch Smart table is the right place to start and your league rulebook is the final word.
Pitch Smart Limits by Age
The table shows the daily maximum for each age group and the pitch-count ranges that require 0, 1, 2, 3, 4 or 5 days of rest.
| Age | Daily max | 0 days | 1 day | 2 days | 3 days | 4 days | 5 days |
|---|---|---|---|---|---|---|---|
| 7–8 | 50 | 1–20 | 21–35 | 36–50 | — | — | — |
| 9–10 | 75 | 1–20 | 21–35 | 36–50 | 51–65 | 66–75 | — |
| 11–12 | 85 | 1–20 | 21–35 | 36–50 | 51–65 | 66–85 | — |
| 13–14 | 95 | 1–20 | 21–35 | 36–50 | 51–65 | 66–95 | — |
| 15–16 | 95 | 1–30 | 31–45 | 46–60 | 61–75 | 76–95 | — |
| 17–18 | 105 | 1–30 | 31–45 | 46–60 | 61–80 | 81–105 | — |
| 19–22 | 120 | 1–30 | 31–45 | 46–60 | 61–80 | 81–105 | 106–120 |

How Rest Days Work
Rest days are calendar days, and the day of the outing does not count. Here is the arithmetic for a 12-year-old:
- Saturday: throws 48 pitches. That falls in the 36–50 range, so two days of rest are required.
- Sunday and Monday: rest days.
- Tuesday: eligible to pitch again.
If the same pitcher had thrown 52 pitches instead, the 51–65 range applies, and Wednesday is the first day back. Four extra pitches cost a full extra day, which is exactly why coaches need the count in front of them while the pitcher is still on the mound.
Pitch Smart also says no pitcher should pitch in a game three days in a row, even if each outing was short enough to require no rest. Back-to-back days are allowed only when the first outing stayed inside the 0-rest range.
The Mistakes Coaches Make Most
Counting the wrong number. The count that decides rest is the total for the day, across every game the player pitched in. A tournament with two games on Saturday is one day.
Reading the table from the wrong side. The thresholds are ceilings. A 10-year-old at 35 pitches needs one day of rest; at 36 pitches they need two. Coaches who think in round numbers like 40 or 50 tend to owe a day they did not plan for.
Forgetting the bullpen. A pitcher who warms up, sits, and warms up again has thrown a lot of pitches that never appear in the box score. Pitch Smart counts game pitches, but arm fatigue does not know the difference, so treat heavy bullpen days as real workload when you plan the week.
Trusting memory. Games run long, schedules change, and a parent volunteer keeps the book differently every week. Written or digital tracking is the only version that survives a rules dispute with the other dugout.
Skipping the league rulebook. Some leagues lower the maximums, some let a pitcher finish the current batter after reaching the limit, and some add catching restrictions on top. Print your league's page and keep it with the lineup card.
Three Ways to Track Pitch Counts
1. A paper log. The free Coach's Binder includes a printable pitch count and rest log with a row per pitcher per game, so the rest date is written down the moment the outing ends.
2. The free calculator. The pitch count and rest day calculator on this site takes an age group and a pitch count and returns the required rest and the first eligible date. It runs in the browser on any phone.
3. Pitch Chart in ScoutBall AI. When you chart a game in Pitch Chart, the pitch count updates on every tap, and each pitcher's session is saved with the date and total. The bullpen view groups your staff as available, active and done, so who can pitch today is visible at a glance instead of a calculation you run between innings.
Pitch count rules are simple on paper and easy to break in a dugout. Know the daily maximum for your age group, learn the rest thresholds instead of round numbers, count the whole day rather than the game, and write every outing down somewhere that outlives the weekend. Do that, and the rules stop being a source of forfeits and start doing what they were written for: keeping your pitchers healthy through the season and the seasons after it.
