Slide or Avoid. 

If a play is being made, or is about to be made, it is MANDATORY for players of all age groups to slide or make an effort to avoid a collision at all bases and home plate. Failure to do either will result in an automatic 'out'. The ball is dead and no runner may advance beyond the base that was last legally acquired. An umpire will have the option of ejection if the incident warrants such a measure
