Washington High School Pitch Count Rules (WIAA)
- Last checked Nov 1, 2026
- By Julien Levadoux
Under WIAA rules, Washington high school pitchers may throw up to 105 pitches a day. Up to 30 pitches needs no rest; 76 or more needs 3 calendar days of rest. The extra limits are below.
The WIAA rest table
High school (all levels) · 105 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–30 | None: may pitch the next day |
| 31–50 | 1 calendar day |
| 51–75 | 2 calendar days |
| 76–105 | 3 calendar days |
Other limits
- Applies to all regular-season and postseason games, including tied, suspended, discontinued or protested games.
- Based on pitches thrown in a calendar day; if the count is under 105 at the start of an at-bat, the pitcher may finish that at-bat.
- Every legal or illegal pitch from the mound to a batter counts.
- Home scorebook is the official pitch count unless the schools, league, district or WIAA designate otherwise.
- Violations are treated as using an ineligible player; after reaching the daily max (unless finishing the at-bat) the pitcher is ineligible to pitch.

The calculator above is set to Washington. 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. 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 Washington table requires is 3 days.
Where the rule comes from
These numbers are from the association’s own document: WIAA Handbook, High School Baseball Pitcher Limitation, read as the WIAA Handbook 2023-24. 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.
