OUTFIELD FLY BALLS
An outfield fly ball is judged to be fair or foul by the relationship of the ball to the foul line at the moment it first touches the ground, or where it first touches a fielder. If the ball touches a fielder in-flight, the judgment is made at where the ball was when it was touched, NOT from where it may land after a miss, or drop of the ball, by a fielder. The position of the fielder is irrelevant. You only focus on the ball and the foul line.
