Under MHSAA rules, Mississippi high school pitchers may throw up to 120 pitches a day. Up to 25 pitches needs no rest; 106 or more needs 4 calendar days of rest. The extra limits are below.
The MHSAA rest table
All levels · 120 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 |
| 76–105 | 3 calendar days |
| 106–120 | 4 calendar days |
Other limits
- If a pitcher reaches 120 in the middle of an at-bat, he may finish that batter without penalty.
- Only pitches thrown to a batter count.
- Doubleheaders: a pitcher who throws 25 or fewer in the first game may pitch the second; at 26 or more he is ineligible for the second game.
- Rest applies only to pitching; the player may bat and play other positions.
- Pitch counts and results must be entered in MaxPreps within 24 hours; the home team's recorder is official.
- Penalty: using an ineligible pitcher forfeits the game in which he pitched plus a $250 fine to the school; failing to submit pitch counts properly also carries a penalty.

How to read the rule
Rest is counted in calendar days, after the day the pitcher threw. 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 Mississippi table requires is 4 days.
Where the rule comes from
These numbers are from the association’s own document: MHSAA Baseball Pitch Count Summary, read as the MHSAA pitch count summary (Jan 31, 2017). 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.
