- By Julien Levadoux
Under MPSSAA rules, Maryland high school pitchers may throw up to 105 pitches a day (sophomores to seniors). Up to 30 pitches needs no rest; 76 or more needs 4 calendar days of rest. The other tables and the extra limits are below.
The MPSSAA rest tables
Sophomores to seniors · 105 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–30 | None: may pitch the next day |
| 31–45 | 1 calendar day |
| 46–60 | 2 calendar days |
| 61–75 | 3 calendar days |
| 76–105 | 4 calendar days |
Freshmen · 95 pitches a day at most
| Pitches in a day | Rest before pitching again |
|---|---|
| 1–30 | None: may pitch the next day |
| 31–45 | 1 calendar day |
| 46–60 | 2 calendar days |
| 61–75 | 3 calendar days |
| 76–95 | 4 calendar days |
Other limits
- Limits are by grade (freshman 95; sophomores-seniors 105), not by team level.
- A pitcher who reaches the daily max mid-at-bat is allowed to finish that hitter.
- The rule is in continuous effect between the regular season and playoffs; suspended games use current limitations.
- Counted: strikes (incl. fouls), balls, balls in play, outs. Not counted: warm-ups, injury/delay pitches, pickoff plays. Intentional walk without pitches = 0.
- Coaches list each pitcher's limits on the lineup card, exchange pitch count charts before the game, and report counts on Smartsheet by noon the next day.
- Penalty: forfeit of the game in which an illegal pitcher was used.

The calculator above is set to Maryland. 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 Sophomores to seniors table, a pitcher who throws 68 pitches on a Tuesday needs 3 calendar days of rest, so the first day they can pitch again is Saturday. The most rest any Maryland table requires is 4 days.
More than one table
Maryland doesn’t use one table for everyone. Sophomores to seniors: up to 105 pitches a day, 76+ pitches means 4 calendar days of rest. Freshmen: up to 95 pitches a day, 76+ 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: MPSSAA Baseball Bulletin 2026, read as the MPSSAA 2025-26 Spring Bulletin. 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.
