The Hardball Times:The inside change-up: courage or folly?
Conventional wisdom has it that the changeup should never be thrown inside. John has a look to see if there is any wisdom in the conventional wisdom.

    John, can you show Lilly's previous pitch and location, prior to the CH, and how that compares to the other pitchers?

    I will guess that would be one way to figure if he meant to throw inside.  How often would a pitcher throw two balls consecutively inside, especially if it's a FB/CH combination?

    Unless you've already done it, I think that would be a great article on how pitchers "mix 'em up", in terms of distance gap between back-to-back pitches, break, and speed.

      Hey Tom,

       I think the question of sequencing is an interesting one, and I've been mulling over how to approach the problem generally.

      I don't think, though, in this case we'll be able to infer much about Lilly's intention based on the previous pitch.  

      A better way would be to look at video, where you can see where the catcher sets up.  If some hardy soul would want to undertake that, I would happily provide a list of Lilly's inside changeups, including game, inning, batter, count, etc.

    I for one was in the Hernandez camp, although, as you say, John, "never" is a strong word.

    I think your data completely refute Hernandez' claim.  There are clearly some pitchers that use the inside change up, at least some of the time.

    The problem, even for Keith, is that there are so many more outdide changeups that when you watch games or even play in them for 15 years, like Keith, you apparantly forget that you've seen or experienced an intentional inside change.

    Another example of how inefficient the human mind, our senses, and our memory are at storing and processing data.

    Nice job!

      Thanks, Mitchel.

       You've pretty much summed up here my own view, especially the part about the inefficiency of our senses and memory.  Gilovich's book on the subject is a good read, if you haven't  already.

    the thing about lilly is that he pounds the zone inside so it throwing it inside makes sense for him but in my experience it seems that change ups away are more effective

    Commentators like to say about inside off-speed pitches, when they work, that "there's nothing he could do with that pitch but yank it foul."
