Ok NOW try this one:
Slow roller down 3rd baseline, ball is dancing between fair and foul, F2 is walking the line over the ball and she picks it up and fires to F3 to attempt to get the BR out. Ball is called foul by PU. Once ball is foul, BR becomes a batter only again so now F2 has made an attempted put out with no runner or batter runner in play.
Ok I am waiting to see what other rule I need to look up now and begin to second guess based on that play.
