Non-wood bats must have the USA Baseball stamp (USSSA is not legal) and be no more than 2 5/8” in diameter at the widest part of the barrel. All bats must comply with rule 1.10 of the official baseball rules.

When on Offense
- Entire rosters will be placed in the batting order (continuous batting lineup will be used)
- Late arriving players will be placed at the bottom of the batting order per coach’s discretion
- Dropped third strike and infield fly rules are in effect - Stealing bases is allowed but base runners are not allowed to lead off from base and may only leave base as the pitch crosses home plate. Base runners who are determined to have left base early by the umpire will be corrected by the umpire per rule 7.13 of the Little League Rule Book
- Base runners are prohibited from using head-first slides into bases, though may use head-first dives back into bases already passed
- On-deck batters (or any other player not currently batting) are not allowed. When a team is on offense, all players (besides the active batter, base runners, or players serving as properly equipped base coaches) must remain in the dugout.

- Pitchers who throw 41 or more pitches are not allowed to play catcher for the remainder of the day; Note: this is a hard threshold and does not allow for a pitcher to finish an at bat.

This includes double-headers.
- Only rostered players (no coaches) are allowed to warm up pitchers on the field in the bullpen area in pre-game preparation or during games; this player must wear a catcher’s helmet with dangling style throat guard when warming up a pitcher.

- Players of Little League age 11 or 12 can pitch a maximum of 85 pitches per game.
- Players of Little League age 9 or 10 can pitch a maximum of 75 pitches per game.
- Once removed from the mound, a pitcher cannot return to pitch in that calendar day, even if
only one pitch is thrown. This includes double-headers.
- A mandatory number of days rest is required for baseball pitchers, based on the number of
pitches thrown that day:
Pitches Thrown Mandatory Days of Rest
1 – 20 Pitches 0 calendar days (may pitch following day)
21 – 35 Pitches 1 calendar day of rest (cannot pitch next day)
36 – 50 Pitches 2 calendar days of rest (cannot pitch next two days following game)
51 – 65 Pitches 3 calendar days of rest (cannot pitch next three days following game)
66 or More Pitches 4 calendar days of rest (cannot pitch next four days following game)
- If a pitcher reaches a day’s of rest threshold while facing a batter, the pitcher may
continue to pitch until the batter reaches base, is retired, or the third out is made. The
pitcher will only be required to observe the calendar days of rest for the threshold that
was reached during that at-bat if removed from the mound prior to facing the next
batter.
