- By Julien Levadoux
Under PIAA rules, Pennsylvania high school pitchers may throw up to 100 pitches a day. Up to 25 pitches needs no rest; 76 or more needs 3 calendar days of rest. The other tables and the extra limits are below.
The PIAA rest tables
High school, regular season · 100 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–25 | None: may pitch the next day |
| 26–50 | 1 calendar day |
| 51–75 | 2 calendar days |
| 76–100 | 3 calendar days |
Junior high · 75 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–20 | None: may pitch the next day |
| 21–30 | 1 calendar day |
| 31–45 | 2 calendar days |
| 46–60 | 3 calendar days |
| 61–75 | 4 calendar days |
Other limits
- Weekly maximum: 200 pitches per calendar week (Sunday–Saturday); 210 in District/state playoff contests; junior high 150.
- No pitcher may appear on more than 2 consecutive days of competition (junior high: 2 consecutive calendar days).
- A pitcher who reaches 100 during an at-bat may keep pitching to that batter (or a substitute for that batter); the appearance is credited as 100 pitches.
- District and state playoff games allow 105 pitches a day and 210 a week. PIAA's table doesn't list the rest after 101–105 pitches, so ask your district.
- Schools must enter pitch counts in MaxPreps by 12:00 noon the day after the game (GameChanger recommended); scorekeepers should confirm counts at least once per inning; in District/state games an official pitch counter is named by the contest manager.

The calculator above is set to Pennsylvania. Enter the pitches thrown and the day, and it shows the rest required and the first day the pitcher can throw again.
How to read the rule
Rest is counted in calendar days, after the day the pitcher threw. On the High school, regular season table, a pitcher who throws 63 pitches on a Tuesday needs 2 calendar days of rest, so the first day they can pitch again is Friday. The most rest any Pennsylvania table requires is 4 days.
More than one table
Pennsylvania doesn’t use one table for everyone. High school, regular season: up to 100 pitches a day, 76+ pitches means 3 calendar days of rest. Junior high: up to 75 pitches a day, 61+ pitches means 4 calendar days of rest. Pick the one that fits in the calculator; both are printed below it.
Where the rule comes from
These numbers are from the association’s own document: PIAA Baseball Pitching Restriction 6-2-6 (printed in PIAA District III 2026 regulations), read as the PIAA Baseball Pitching Restriction 6-2-6 (revised July 17, 2019). Associations can change their rules between seasons, so if the season is about to start, check the association’s current baseball manual too. Your league or tournament may also set stricter limits than the state.
Keeping the count is usually the coaches’ job, often with both teams’ counts compared after the game. The pitch count log has a line for every pitcher and game.
