Watching baseball on TV I've only seen pitchers aim for 3 locations: low-inside, low-outside, and high-inside. Occasionally the catcher will set up for something low and over the plate, or up high abive the strike to get the batter to chase a fastball. But what about middle-in, or middle-high, or high-outside? Is there ever a time when a pitcher should aim his slider middle-in, or their splitter high and over the plate, or their change-up high and away?
