Henry from San Carlos, CA asks:
Are there any circumstances in which a fan can be on the field during play and not be charged with spectator's interference, excluding falling onto it?
No, there is no circumstance that would permit a fan to be on the field during play. Fan interference will only be called if a spectatortouches a live ball or touches or in anyway prevents a fielder from making a play.
However, most ballparks have rules in place that if a fan goes onto the field without permission at any time he or she will be ejected from the ballpark, fined, and most likely have to spend the night in jail. They also don't get to keep the ball they interfered with.
