Under MHSA rules, Montana high school pitchers may throw up to 88 pitches a day (first five weeks (to April 19 in 2026)). Up to 28 pitches needs no rest; 75 or more needs 4 calendar days of rest. The other tables and the extra limits are below.
The MHSA rest tables
First five weeks (to April 19 in 2026) · 88 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–28 | None: may pitch the next day |
| 29–44 | 1 calendar day |
| 45–59 | 2 calendar days |
| 60–74 | 3 calendar days |
| 75–88 | 4 calendar days |
From April 20 in 2026, through the postseason · 110 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 |
| 51–70 | 2 calendar days |
| 71–90 | 3 calendar days |
| 91–110 | 4 calendar days |
Other limits
- Limits apply from the first day of practice; the lower chart (max 88 per game, or per day in a doubleheader) covers the first five weeks, the higher chart (max 110) applies from April 20, 2026 through the postseason.
- No varsity/sub-varsity pitcher may throw more than 100 pitches over two consecutive days; reaching that limit means three days of mandated rest.
- A pitcher may not pitch three days in a row, no matter how few pitches were thrown the previous two days.
- A pitcher who reaches the daily maximum during an at-bat may finish that batter, then must leave the mound.
- A varsity starting pitcher may not pitch in a JV game except in extraordinary circumstances approved by the Executive Director.
- Home team book is official; teams verify counts after each game and each school enters its pitch counts in GameChanger.
- Montana teams must follow these limits even when playing out of state. A violation forfeits the game.

The calculator above is set to Montana. 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 First five weeks (to April 19 in 2026) table, a pitcher who throws 67 pitches on a Tuesday needs 3 calendar days of rest, so the first day they can pitch again is Saturday. The most rest any Montana table requires is 4 days.
More than one table
Montana doesn’t use one table for everyone. First five weeks (to April 19 in 2026): up to 88 pitches a day, 75+ pitches means 4 calendar days of rest. From April 20 in 2026, through the postseason: up to 110 pitches a day, 91+ 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: MHSA 2025-26 Pitch Count Rules, read as the MHSA 2025-26 Pitch Count Rules. 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.
