A good player can break before the ball reaches the batter if she knows what she is looking for....otherwise she has to play the batter first and then break....positioning is key...
once they get the timing right, the SS will get there just in time to take the throw... with a catcher that can pop quickly and a dependable SS, you will get a lot of runners...
Let's not wordsmith this too much...What I meant was she will get at the right time (there not too early and not too late).... The point was working on it in practice to get the timing right.
