help with getting into position

[shipwreck]

It seems like I am not getting into the best position when a girl is stealing. This happens most often when I am positioned on the fielder's left shoulder. If she gets her lead and then heads back to her base, I go along with her to be in best position in case of a throw back. My problem is if she is stealing and gets a good jump. I am in a set postion at the time of pitch. She gets a running start. By the time she is approaching the base she is trying to steal, I am too far behind her, or if I am close, I am still moving to make the call. What tips do you have to be able to get there and set up before she does? Should I always start on the fielder's right shoulder to be able to get a head start, despite what the umpire manual says, or any other help would be appreciated. Maybe I should head toward the advanced base first, and if she isn't stealing, could follow her back in case of a pickoff attempt. I am by no means slow, it's just I seem to be behind the play too often. Dave
