Youth and high school baseball rules, explained for parents and coaches.

Pitch Count Calculator: Rest Days by State and League

Pick Little League, Pitch Smart or your state's high school association, then the age or level, and enter the pitches thrown. The calculator shows the rest required, the first day the pitcher can throw again, and the daily limit, with the table and its source.

How rest days are counted

Every rule set here counts calendar days of rest after the day the pitcher threw. “No rest” means the pitcher may pitch the next day. Three days of rest after pitching on a Monday means resting Tuesday, Wednesday and Thursday and pitching again on Friday. The calculator does that arithmetic for you.

Most rule sets also have limits that a single number can’t capture. A pitcher may usually finish the batter they’re facing when they reach the daily limit. There are caps on pitching several days in a row, and rules for pitchers who also catch. The calculator lists the extra rules for whichever set you pick.

Which rules apply to your player

  • Little League teams follow Little League’s pitch count regulation, by the player’s league age.
  • High school teams follow their state association’s rules, which differ from state to state. Some go by team level, some by grade, and a few change partway through the season. The state-by-state table shows them all.
  • Travel and other youth leagues often use MLB and USA Baseball’s Pitch Smart guidelines, or their own rules. When in doubt, ask the league which ones it enforces.

Where the numbers come from

Each rule set was read in the governing body’s own document, and the calculator shows which document and when we checked it. States we haven’t confirmed yet are marked “being checked” and aren’t calculated, rather than guessed. If your league’s rule differs from what you see here, the league’s rule is the one that counts. Tell us and we’ll check it.

Explained in our own words, not an official ruling: in a competition, the committee, league or umpire decides, and local rules apply.
