This is not the easiest code to do, and takes some practice to perfectly do every time. Just choose a fast ball, set it in the lower corner opposite the batter (if you have a right-handeder up for a batter, the set it in the lower-left corner), and make the ball just barely touch the outside corner. The batter shouldn't swing, and the umpire should call it a strike. They will hit it sometimes, but very rarely, and will sometimes ball. Please don't complain to me or GameSages or anyone because this is usually human error or a really good batter. Like I said, this is hard to perfect.
