Going from Little League's Major Division to high school, runners can lead off and steal, so balks are called. The field grows from 60-foot bases to 90 feet, with the mound at 60 feet 6 inches. Bats must be BBCOR, games go to seven innings, playing time is up to the coach, and pitch count limits come from the state.

The table above puts Little League’s Major Division (ages 9 to 12) next to high school. Most players make the jump through Little League’s 50/70, Junior or Senior divisions, or a travel team, and those add the high school rules a few at a time. Rules by league shows every division.
The five changes that matter most
1. Runners lead off, and pitchers can balk. In the Major Division a runner can’t leave the base until the pitch reaches the batter. In high school, runners take leads and steal on the pitcher’s motion, so pitchers have to hold them on, and an illegal move with runners on base is a balk: every runner moves up.
2. The field is much bigger. Bases go from 60 feet to 90, and the pitching distance from 46 feet to 60 feet 6 inches, off a raised mound. Throws from the outfield and from shortstop get a lot longer. See field dimensions.
3. Different bats. Little League bats carry the USA Baseball mark; high school needs BBCOR bats, no more than 3 ounces lighter than their length. A high school bat change is coming in 2028. UsedBatFinder covers it in high school bat rules.
4. Playing time isn’t guaranteed. In the regular season, Little League’s mandatory play rule makes sure every player fields and bats. High school has none: the coach decides.
5. Pitch counts come from the state. Little League has one national table by age. In high school, each state association sets its own limits and rest days. Look yours up in the pitch count rules by state.
What doesn’t change
Three strikes and four balls, the infield fly rule, and the dropped third strike work the same way. High school also allows re-entry: a starter can come out and go back in once, in the same spot in the batting order, much as in Little League.
Metal cleats
Major Division players must wear molded cleats; metal spikes are allowed from the 50/70 Division up and in high school. Check before buying.
Explained in our own words, not an official ruling: in a competition, the committee, league or umpire decides, and local rules apply.
