Re: Nice piece on Johnny Cueto from fangraphs
I remember left handers started out something like 0-for-18 against Cueto through his first two or three starts. That's when he was mixing in his changeup more. Like remdog said, that's his newest pitch, so while it's already a great pitch he may not have been fully comfortable with it yet. That should come with experience.
I miss Adam Dunn.
