- By Julien Levadoux
Under IHSAA rules, Indiana high school pitchers may throw up to 120 pitches a day (varsity). Up to 35 pitches needs no rest; 101 or more needs 4 calendar days of rest. The other tables and the extra limits are below.
The IHSAA rest tables
Varsity · 120 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–35 | None: may pitch the next day |
| 36–60 | 1 calendar day |
| 61–80 | 2 calendar days |
| 81–100 | 3 calendar days |
| 101–120 | 4 calendar days |
Sub-varsity · 90 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–25 | None: may pitch the next day |
| 26–35 | 1 calendar day |
| 36–60 | 2 calendar days |
| 61–80 | 3 calendar days |
| 81–90 | 4 calendar days |
Other limits
- Max is per contest and per calendar day (doubleheader pitches are combined).
- A pitcher who reaches the maximum during an at-bat may finish that batter; the count is then recorded as the level's maximum regardless of pitches thrown in that at-bat.
- A pitcher with more than 60 pitches over two calendar days must rest one calendar day (may finish the batter if 60 is reached mid-at-bat; recorded as 60).
- A replacement for a pitcher who reached the maximum gets up to 16 warm-up throws.
- Schools must keep an IHSAA Pitch Count Chart for every pitcher after each contest.
- Penalty: a school that intentionally uses a pitcher in violation must forfeit that contest and report the violation in writing to the IHSAA.

The calculator above is set to Indiana. 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 Varsity table, a pitcher who throws 91 pitches on a Tuesday needs 3 calendar days of rest, so the first day they can pitch again is Saturday. The most rest any Indiana table requires is 4 days.
More than one table
Indiana doesn’t use one table for everyone. Varsity: up to 120 pitches a day, 101+ pitches means 4 calendar days of rest. Sub-varsity: up to 90 pitches a day, 81+ 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: IHSAA By-Law 51-4, as amended, read as the IHSAA By-Law 51-4 (2023-24 By-Laws). 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.
