It’s always been my understanding that when a ball is hit the runner can actually purposely slow down in front of a ground ball to an infielder as long as they do not make contact with the ball or fielder and visually obstruct them. Is this actually interference or is the runner legally allowed to do this? I know if a runner is simply avoiding a ball or fielder it is fine but I am curious about the intentional distraction without hindering anything else of the fielders ability to field the ball.
