Cindy, there is just no telling if your player will get 3 strikes. The algorithym that they use is way to too complicated to decide just from scores what will happen with that player; it is all based on what the score was, what the opponents' dynamic ratings are, etc., etc. Just too hard to calculate without all the information that is in the computer and the dynamic ratings of the opponents.
Don't worry, just go play! Whenever you have a self rated player they can get DQed. That's the way of the USTA and it affects all teams equally.
