Jeff,
Doesn't matter if it's his UNCOMFORTABLE zone; unless the ball can't make the turn from where he has to move, he has to learn to "bowl" from his discomfit area unless he allows it to become his discomfiture. Practice will take care of this.
However, Alex, if you polish it, you may not be able to use it for the first game. Do you want it for game 1 & 2 or game 2 & 3? Or preferably, all 3 games.
As an alternative, do you have a ball that hooks less for game 3?
