Under 7.06 (b) when the ball is not dead on obstruction and an obstructed runner advances beyond the base which, in the umpire's judgment, he would have been awarded because of being obstructed, he does so at his own peril and may be tagged out. This is a judgment call. NOTE: The catcher, without the ball in his possession, has no right to block the pathway of the runner attempting to score. The base line belongs to the runner and the catcher should be there only when he is fielding a ball or when he already has the ball in his hand.
