One of Hillhouse's most common taught theories is why the softball goes where is does when it is thrown. He teaches why the softball goes high or low or to far inside or to far outside. He teaches that they should not pull the arm straight up but actually across their body more so that they can push hard with the elbow and not to use a straight arm to much and can use the natural flow of the body. He also says that you have to point with the front shoulder so you can position where you want the softball to go. If you keep your front shoulder straight then the softball will go straight but if the shoulder gets out of line then the softball will not go where the pitcher wants it to.
