12U game. Runner on 1st, 1 out. Batter hits a pop up behind 1st base. 2nd baseman runs to catch pop up and 1st baseman runs to cover 1st for potential double play. Runner on 1st runs back to first and in doing so, collides with 1st baseman. Runner gets back safely to 1st base and no throw is made to 1st. Runner is also called out for interference because of collision with 1st baseman.
Was this the right call?
