7.03 Two runners may not occupy a base, but if, while the ball is alive, two runners are touching a base, the following runner shall be out when tagged. The preceding runner is entitled to the base. If such a runner, forced to advance, is put out for the third out before a preceding runner, also forced to advance, touches home plate, the run shall score. Two out, bases full, batter walks but runner from second is overzealous and runs past third base toward home and is tagged out on a throw by the catcher. Even though two are out, the run would score on the theory that the run was forced home by the base on balls and that all the runners needed to do was proceed and touch the next base.
Ball is in play.
If the fielder or catcher, after having made a legal catch, should fall into a stand or among spectators or into the dugout after making a legal catch, or fall while in the dugout after making a legal catch, the ball is dead and runners advance one base without liability to be put out. While he is attempting to steal a base, the batter is interfered with by the catcher or any other fielder. When a runner is entitled to a base without liability to be put out, while the ball is in play, or under any rule in which the ball is in play after the runner reaches the base to which he is entitled, and the runner fails to touch the base to which he is entitled before attempting to advance to the next base, the runner shall forfeit his exemption from liability to be put out, and he may be put out by tagging the base or by tagging the runner before he returns to the missed base. The ball is in play and the batter may advance to home base at his peril. Two bases, if a fielder deliberately touches a thrown ball with his cap, mask or any part of his uniform detached from its proper place on his person.
