Here are some of the updated/new rules in our Rule Book:

8.7 Scoring Runner From Third Base

Applies to 11u & 14u Divisions
High School Divison does not use this rule.

A runner on third base may only score on:

  1. A batted ball
  2. A bases‑loaded walk
  3. A bases‑loaded hit‑by‑pitch
  4. A defensive error made while attempting to retire that runner
    • Example: a pick‑off attempt at third base

A runner may NOT score from third on:

  • Passed balls
  • Wild pitches
  • Steals of home
  • Throws back to the pitcher
  • Dropped third strikes
  • First‑and‑third steal attempts (runner on 1st attempting to steal 2nd)

Penalty

  • The runner is returned to third base.
  • Other runners return to their previous base unless forced to advance.

Examples

Example 1:
Runners on 1st and 3rd.
Batter walks on a passed ball.
Runner from 3rd attempts to score.
