How about this scenario: Leadoff gets on first, next batter bunts the ball runs right down the line, was easily safe with good throw, but the fielder airmails the throw over the second baseman, as the runners reach second and third, umpire decides the girl obstructed the throw by running down the line. Next batter hits single which easily would have scored both runners. Lose tight game 1-0. In 7 years of watching and coaching have never had that call.
