Little League Baseball Rules: The Complete Coach's Reference

Little League International governs youth baseball and softball for millions of players across divisions from Tee Ball through Juniors (ages 4-16). The rules that matter most on game day are all covered here with the specific numbers coaches need to know: pitch count limits, mandatory rest days, the catcher-to-pitcher restriction, minimum play requirements, and substitution rules.

The Rules Coaches Violate Most Often

Three rules cause the most forfeits, protests, and board complaints in Little League:

1. Pitch count rest days. A coach pitches a kid on Tuesday who threw 55 pitches on Saturday. Fifty-five pitches requires three rest days (Sunday, Monday, Tuesday), so he isn't eligible until Wednesday. Game gets protested. Forfeit. Rizzler's rule compliance engine prevents this by tracking every pitch and calculating eligibility automatically.

2. Minimum play. A kid sits on the bench for four innings and the coach forgets to put him in. At the LL level, every rostered player must get at least one at-bat and play six consecutive defensive outs per game. Rizzler's playing time tracking flags players who haven't met the minimum.

3. Catcher-to-pitcher violations. Your catcher catches innings one through four, then you bring him in to pitch in the fifth. That's a violation. Once a player catches four or more innings, they can't pitch that calendar day. Read the full catcher-to-pitcher rule.

How Rizzler Helps You Stay Compliant

Rizzler is built with Little League rules baked in. When you plan a game, assign a pitcher, or make a substitution, Rizzler checks the rules before you make a mistake. Pitch count limits, rest day calculations, catcher-to-pitcher restrictions, and minimum play tracking all run automatically.

Frequently Asked Questions

Where can I find the official Little League rulebook?

The official rulebook is published at littleleague.org. This reference is a coach-friendly summary based on the current rules; always defer to the official publication for disputes.

Do Little League rules apply to softball too?

Little League governs both baseball and softball, but some rules differ, particularly pitch count thresholds, field dimensions, and pitching distance. This reference covers baseball rules; softball variations are noted where applicable.

Does Rizzler automatically enforce Little League rules?

Rizzler's rule compliance feature monitors pitch counts, rest days, playing time, and catcher-to-pitcher restrictions in real time. It warns you before a violation happens.

What happens if my league uses modified rules?

Many local leagues modify certain Little League rules (longer games, different age groupings, etc.). Rizzler lets you set custom rules so compliance tracking matches your league's actual regulations.

How are Little League rules different from travel ball rules?

Significantly. Little League has stricter pitch count limits, mandatory rest days, minimum play requirements, and continuous batting orders. Travel ball (USSSA, Perfect Game, etc.) generally gives coaches more flexibility. See the pitch count rules comparison.
