Under OSAA rules, Oregon high school pitchers may throw up to 110 pitches a day. Up to 25 pitches needs no rest; 86 or more needs 4 calendar days of rest. The extra limits are below.
The OSAA rest table
All levels · 110 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–25 | None: may pitch the next day |
| 26–45 | 1 calendar day |
| 46–60 | 2 calendar days |
| 61–85 | 3 calendar days |
| 86–110 | 4 calendar days |
Other limits
- Exception after 61-85 pitches (Level Three): on his third day of rest he may throw up to 45 pitches; if under 25 he may pitch the next day (110 max); if 26-45 he needs one full day of rest.
- Exception after 86-110 pitches (Level Four): on his fourth day of rest he may throw up to 25 pitches, then may pitch the next day with a 110 max.
- A pitcher reaching 110 during an at-bat may finish that batter, then must leave the mound. No finishing the batter past the 25- or 45-pitch exception limits.
- Crossing 25, 45, 60 or 85 immediately moves the pitcher to the next rest level.
- Policy is based on days, not games: doubleheader pitches are added together.
- Only pitches actually thrown count (intentional walks only if pitches were thrown); warm-ups excluded; pitches count even if the game is later postponed or cancelled; switching arms does not reset.
- Strongly advised that a player not play pitcher and catcher in the same game.
- Penalty: forfeiture of the contest in which the pitcher exceeds 110 or violates rest.
- Pitch counts must be entered on the OSAA website by 10 a.m. the day after the contest (varsity before the next day's game); failure may bring a school fine, coach suspension or player ineligibility.

How to read the rule
Rest is counted in calendar days, after the day the pitcher threw. A pitcher who throws 73 pitches on a Tuesday needs 3 calendar days of rest, so the first day they can pitch again is Saturday. The most rest any Oregon table requires is 4 days.
Where the rule comes from
These numbers are from the association’s own document: OSAA Handbook, Participation Limitations - Baseball (Pitch Count Policy), read as the OSAA Pitch Count Policy. 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.
