Rec ball. Runner going to 2nd, overthrow ball into short center. I bring her to 3rd, throw on its way and I see its off line towards home plate side, I wave her on to home. 3rd in attempt to field thrown ball backs toward foul territory and toward home. Runner make contact altering her path. field Ump throws arm for interferance, catcher catches throw from 3rd baseman who did block ball and makes throw, home ump calls runner out on tag and then reverses for field ump call. Was this correct? I know on a batted ball fielder has right away and runner is out upon contact with fielding defeseman. How does the rules apply to thrown balls. I know that runner cannot purposly interfer with ball in flight etc. I am not sure when feilding throw contact is made with runner trying to progress to next base.
