Catcher catching ball in front of the plate.

[GA Umpire]

F2 only has a right to get the ball after the batter has had a complete, uninterrupted chance to hit the ball.

Meaning, until the ball has completely passed the plate and the batter takes no chance to hit the ball while in flight. For the plate, remember, the ball has to cross the foul line(s) to be a pitch. For the takes no chance, if the batter swings at the ball while it is still in flight and not with the obvious intent to hit the F2's glove(such as a really late swing), then F2 better not hinder him. If the ball is no longer in flight(and bouncing is still in flight), ie. it is completely in the F2's glove, then he cannot be interfered with anymore.

So, if the catcher catches the ball behind the plate and is starting to throw to 2B, then the batter can no longer be interfered with. Now, it is the catcher that can be interfered with.
