Halladay’s pitch mix
Buster Olney had this to say about Roy Halladay’s pitch mix:
The percentage of Roy Halladay pitches that were fastballs in ’11: 27. Pct. of Halladay pitches that were fastballs in ’12: 8.

I have no idea what he’s talking about. First and foremost, Doc doesn’t throw four-seam fastballs. He cuts and sinks the ball, so you can maybe say he throws two different fastballs.
But anyway, I can’t find anything in Doc’s numbers to match up with Buster’s tweet. These are my pitch IDs, and you can see more about Doc based on my tags on his player card.
