High School game (NFHS) - Runner on 1B. Batter hits soft grounder to second baseman. As the second baseman comes in to field ball the fielder either is about to field ball OR fields it cleanly and has ball and about to tag runner coming towards him....the runner crashes into the fielder (leveling the defensive player) as he is proceeding to 2B...everyone was safe as ball was jarred loose from the second baseman.
In either case shouldn't the runner be called out for "crashing" (interfering) into the fielder? Shouldn't the runner in every effort avoid interfering with the fielder by stopping, going around or in front of fielder? Umpire did not call anything saying it was "incidental contact"
Also in NFHS does it not state you cannot "crash" into the catcher, does this not to apply to any other fielder's?
