Malicious Contact:

  1. Malicious contact is to be penalized whether committed by an offensive or defensive player.  Contact shall be considered malicious if:
    1. the contact is the result of intentional excessive force, and/or
    2. there is an intent to injure.
  2. The umpire shall determine whether contact was avoidable or unavoidable. If the fielder blocks the base path, the runner may make contact, slide into or collide with the fielder as long as the runner is making a legitimate attempt to reach the base/plate.
  3. Runners are instructed to slide or attempt to avoid making contact with a fielder. A player who maliciously runs into another player is to be declared out (unless he/she has scored prior to committing the infraction) and is to be automatically ejected (whether or not declared out).
  4. If the defensive player blocked the base path clearly without possession of the ball, obstruction shall be called. The runner is safe and a delayed dead ball is called.

Double Play Sliding

Rule 6.01(j) has been adopted by Baseball Ontario for the 2016 baseball season. Runners must engage in a bona fide slide when attempting to break up a double play. Runners not engaging in a bona fide slide and making contact with a fielder will be out for interference. For the purposes of this rule, the runner must:

Begin sliding (makes contact with the ground) before the reaching the base; 

Be able and attempt to touch the base with hand or foot; 

Be able and attempt to remain on the base (except home plate) after completion of the slide; and 

Slides within reach of the base without changing paths for the purpose of initiating contact with a fielder.
