Detached Equipment Violations on Batted Balls
If a defensive player deliberately touches a fairly batted ball with detached equipment, all runners, including batter-runner, will be entitled to advance three bases. The violation of the detached equipment rule happens most often when a catcher uses his face mask to scoop a batted ball to help gain control of the ball before throwing to a base. It is often common to see an amateur youth outfielder throw his glove at a batted ball. If the glove makes contact, this is a three base violation.
