Johnny Cueto‘s changeup is currently flatter than it’s been in five years. Literally. To some extent, everything in his arsenal is flat right now, but it’s most radical when you look at the changeup. With that wiggle in his delivery and a possibly falling arm slot, it’s easy to find a culprit. But he’s wiggled forever, why has he lost his drop now?
Take a look. If you ignore the one game in March last year, the last time he had a month with a changeup this flat was in August 2010.
Another thing that is going on right now is that Cueto’s arm slot flattened recently, and that could do something like kill your vertical drop on a pitch.
