Thanks! I appreciate your kind words. If I only had Bosio on speed dial… (I’m sure he’s already spotted this.)

I expect that a good portion is due to fatigue. Arrieta has a weird windup: he looks like he’s effortlessly throwing the ball, but there’s really a lot of movement (the crossfire action). If decreasing his velo is going to help him get back to his good mechanics, then that’s a good route to explore. But he’s pitching very upright, and it’s borne out by the eye test. Thanks for the comment, Victor.

Saw recently that he’s actually worked on decreasing his velocity slightly in order to re-calibrate his mechanics, so you might be on to something here.

I wonder how much of this drift is due to usage. He pitched a career high innings last year, often in high leverage situations. Perhaps the small change in mechanics is in order to keep his velocity up, but negatively affecting his other pitches.

Brilliant analysis. Thanks.
