SSUSA rule 8.2C1: "8.2 BATTER BECOMES A BATTER-RUNNER (C) When he bats a fair ball even though it strikes another player, umpire or their attached clothing or equipment. (1) If the runner is hit with a fair batted ball while touching a base, he is not out ... after the runner in contact with the base is hit by the batted ball, it shall be the same as hitting the ground. Since the ball remains live the defense is free to make whatever plays are available. If the defensive player is behind the base runner [he was] the ball is ruled dead, the hitter is awarded a base hit and runners are advanced only if forced to advance.
Again, today's umpire/managers got it right when ball struck runner on 3B. Outstanding sportsmanship by managers Alberts (Team 2) and Allen (Team 3).
