I believe you covered this in the "wrinkle" paragraph, but I just wanted to make sure of my understanding of most codes: The umpire must decide which specific fielder has a play on the ball and only that fielder has the right of way to field the batted ball. The other fielders must yield right of way to the runner(s).
