Hmmmm...have I found the answer?
The OP said F1 faked the throw to 2B while all runner were on base. "Play" is defined in Rule 1 as "an attempt by a defensive player to retire an offensive player..."
If the runners are on base, how can F1's fake be an attempt to retire the runner?
Therefore, has a "play" been made?
Still, I have to say that if this happened in a game I was working the game would be over.
