Very curious regarding what the obviously experienced and learned posters here think about the change-up.
When should you throw it? How often? In what counts? In what man-on situations? How often do you show it? Should it ever be thrown for strikes? Do you wait until second time through the order to use it? If they're not touching the fastball, should you slow down the batter's swing by using it? Etc., etc.--please add whatever pertinent suggestions, theories, experiences, you care to.
