The Little League rulebook is a couple hundred pages, and the part a volunteer coach or a bleacher parent actually needs fits on one. Which division your kid is in, what the field looks like, whether he can steal, how many pitches he can throw, and the six plays that start an argument every Saturday. That’s this post. Little League rules explained by someone who isn’t the rulebook, with the official pages linked where the numbers live, because the numbers change and the rulebook always wins.
This is the rules pillar of our coaching baseball hub. The everything-else-before-the-first-practice list is in the first-time coach guide. One caveat that applies to every line below: local leagues add their own rules on top of these (time limits, run caps per inning, two-out innings in tee ball), and your league’s current rulebook overrides anything you read here.
The Divisions and What the Field Looks Like
Little League runs six baseball divisions from tee ball to age 16, and the field changes twice along the way. That second change, at 13, is the biggest single event in a youth player’s baseball life and most parents don’t see it coming.
| Division | League ages | Bases | Mound | What’s different |
|---|---|---|---|---|
| Tee Ball | 4 to 7 | 60 ft | None (tee) | Fun, fitness, fundamentals. One season required before a player can be evaluated for the next level. Division-specific bats and balls. |
| Minor League | 5 to 11 (up to 12) | 60 ft | 46 ft | Coach pitch, machine pitch, or player pitch, set by the local league. A 5 or 6 year old with a tee ball season behind him can move to coach pitch. |
| Major (Little League) | 9 to 12 | 60 ft | 46 ft | The division everyone means by “Little League.” No leads. Leagues may limit it to 10 to 12 or 11 to 12. |
| Intermediate (50/70) | 11 to 13 | 70 ft | 50 ft | The transition field. Runners can lead off and steal at any time, and there’s an on-deck batter. |
| Junior League | 12 to 14 | 90 ft | 60 ft 6 in | The full-size field. Modified dimensions allowed in the regular season. |
| Senior League | 13 to 16 | 90 ft | 60 ft 6 in | Full field, full rules. |
Those are the numbers from Little League’s divisions page, as of the 2026 season. “League age” isn’t birthday age; it’s the age chart Little League publishes each year, and it decides which division a kid can play in. Ask your league which chart they’re using before you assume.
The coaching books put it plainly: the younger the kid, the smaller the field, because putting small legs on a regulation diamond makes the bases feel a time zone away and the kid quits. Sixty-foot bases and a 46-foot mound is the small field. Ninety and 60 feet 6 inches is the big one. Everything about a 13-year-old’s season follows from that jump; the big-field guide covers it, and the field dimensions by age post has the layouts.
The Rules That Change by Division
Most of the confusion in youth baseball comes from rules that exist in one division and not the next. These are the ones that matter.
- No leads until Intermediate. In the Major division and below, a runner can’t leave the base until the pitch reaches the batter. Kids can still advance on a passed ball or a wild pitch, which is where most “steals” at 10U actually come from. At 50/70 and up, runners lead off and steal like real baseball.
- Mandatory play. In the regular season every kid on the roster gets at least one plate appearance and six consecutive outs on defense in every game. The lineup card is a rule, not a courtesy. A 2026 clarification lets a courtesy runner go in for the pitcher or catcher before they’ve met the requirement.
- The 15-run rule. If one team is up by 15 or more after three innings (two and a half if the home team leads), the game is over. Many local leagues add a 10-run version later in the game and a per-inning run cap in the younger divisions.
- Tee ball and Minors don’t play doubleheaders. No team in those divisions is scheduled for two games in a day.
- Coach pitch and machine pitch are Minor League options, chosen by the local league. Whether the batting team’s coach pitches, how many pitches a kid gets, and whether a walk exists are all local. Ask.
- Local additions at the youngest ages, common enough that the coaching books list them: games by time rather than innings, two-out innings in tee ball, coaches on the field during play, unlimited substitutions, fastballs only, and no stealing until the pitch crosses the plate.
The tee ball and coach pitch guides go through the practical side of those two divisions. The one thing to do before the parents meeting is get your league’s local rules in writing, because you’ll be explaining the “no stealing” rule to a parent who played high school ball and thinks you made it up.
Pitching Rules in One Paragraph
Little League counts pitches, not innings, and the count comes with required rest days that scale with how many pitches were thrown. A pitcher who hits a threshold has to stop after the batter, and a kid who catches can’t pitch (and a kid who pitched a lot can’t catch) under specific conditions the rulebook spells out. The coaching books agree with the principle for a reason: an inning can be three pitches or fifty, and counting innings protects nobody. The current table, the rest thresholds, and how to keep the chart so nobody argues are in the pitch count rules post. Breaking balls aren’t banned by Little League, but many local leagues ban them under 13, and the coaching books say 14 at the earliest anyway.

These come from the standard rules of baseball, not Little League specifically, and they’re the same at every level. Six of them cause most of the yelling.
The Infield Fly
Runners on first and second, or the bases loaded. Fewer than two outs. A high fly ball an infielder can catch easily (not a line drive, not a bunt). When all three are true the umpire calls “infield fly, batter’s out” while the ball is still in the air. The batter is out whether the ball is caught or dropped, and the ball stays live, so runners can advance at their own risk.
It exists to protect the offense. Without it, an infielder could let the ball drop on purpose, force the runners to go, and turn an easy double play. With only a runner on first it isn’t called, because the runner waits to see the catch and the batter usually beats the throw anyway.
The Dropped Third Strike
If the catcher doesn’t catch strike three, the batter isn’t out yet. He can run to first, and the defense has to tag him or beat him to the bag. It applies when first base is empty, or when first is occupied and there are two outs. With a runner on first and fewer than two outs, the batter is just out, again to prevent a cheap double play. A batter who doesn’t try to run is out automatically. Teach your catchers to throw to first on every dropped strike three, and teach your hitters to run every time; the umpire will sort out whether it counts.
Tagging Up
On a caught fly ball, a runner has to touch his base after the ball is touched by the fielder before he can advance. He can go the instant the fielder touches it, even if it’s bobbled. If he leaves early and the defense throws to the base he left, or tags him, he’s out, and the defense can also appeal after the play by tagging that base. The book’s image is a sprinter waiting for the gun. Base coaches earn their keep here with two words: “halfway” and “tag.”
Overrunning First Base
A batter-runner can run through first base and turn into foul territory without being tagged out. If he turns toward second, even a step, he’s live and can be tagged. Kids get this backwards constantly, and the fix is a drill: run through the bag, break down, look to the right for an overthrow. The drills book runs it at every age from 8 up.
Missing a Base and the Appeal
A runner who misses a base and keeps going can be put out by a tag on him or on the base he missed, or by an appeal after the play, before the next pitch. Same for failing to tag up. A run doesn’t count if the third out is made on the batter before he reaches first, on a force, or on an appeal against a runner ahead of the scorer.
The Balk, the Short Version
There are twenty ways to balk and you’ll see two at the youth level. The pitcher doesn’t come to a complete stop in the set position, or he doesn’t step toward the base before he throws to it. A balk is a one-base award to every runner (not the batter). It only matters with runners on, which means it doesn’t exist in Major and below where nobody can lead anyway. Save the balk lesson for 50/70.
Two more that come up: interference (the offense gets in the way of a fielder making a play; the batter or runner is out) and obstruction (a fielder without the ball blocks a runner; runners get the base they’d have reached). And a pitch that gets stuck in the catcher’s or umpire’s gear is a dead ball with a one-base award, which happens more than you’d think with 9-year-old catchers.
Equipment Rules
- Helmets on every batter and runner, in practice and in games. Many leagues require the face guard. The coaching books say no kid stands at the plate without one, ever.
- Bats have to carry the USA Baseball stamp in the Little League divisions through Intermediate, and the league publishes a list of approved bats. A bat without the stamp gets the batter called out and the coach a conversation. Tee ball uses bats and balls made for that division.
- Catchers wear full gear including a throat protector and a cup. The cup isn’t optional for catchers at any age.
- Two 2026 clarifications: pine tar and similar grip substances are permitted at all levels, thumb protectors are allowed, and choke-up assists and knobs are not. Sleeves of any material on a pitcher fall under the same rule now, which in practice means no white or distracting sleeve on the throwing arm.
What Changed for 2026
Little League publishes a changes-and-clarifications list every winter, and the 2026 list is mostly housekeeping: the courtesy-runner clarification for mandatory play, the grip-substance and thumb-protector updates, a note that on an uncaught third strike the fielder and the runner can use either half of a double first base, a scorebook signature requirement removed for forfeits, and mound-visit counts no longer blocking a removed pitcher from returning in the 50/70 and up divisions. Nothing about leads, pitch counts, or the field changed. Read the list once before the season; it takes five minutes and it’s the thing the umpire will cite.
Frequently Asked Questions
Can you steal bases in Little League?
Not by leading off. In the Major division and below, a runner can’t leave the base until the pitch reaches the batter, so a “steal” is really an advance on a pitch that got past the catcher. Leading off and stealing on the pitcher start in the Intermediate 50/70 division at 11 to 13.
What is the mandatory play rule?
Every rostered player gets at least one plate appearance and six consecutive defensive outs in every regular-season game. Keep a chart by inning so you can prove it, because a parent will ask.
How many innings is a Little League game?
It depends on the division and the local league. The coaching books say five-inning games are common at 10 to 12 and the older divisions go longer, and many leagues run the youngest divisions on a clock instead. The 15-run rule can end a game after three innings. The game length post breaks it down by age.
What is the infield fly rule in plain English?
With runners on first and second (or bases loaded) and fewer than two outs, a routine infield pop-up is an automatic out for the batter the moment the umpire calls it, so the defense can’t drop it on purpose and double up the runners.
What age is tee ball in Little League?
League ages 4 to 7, and every player has to play one season of tee ball before being evaluated for the next division. A 5 or 6 year old with that season behind him can move to coach pitch.
