A Few AFL PITCHf/x Leaders

I like the Arizona Fall League. I've been tracking and classifying a lot pitches, thanks to the PITCHf/x installations in Peoria and Surprise. Nearly 10,000 pitches through Saturday's Rising Stars Game.

Let's take a look-see at some of my favorite stats. These are based only on PITCHf/x data. Some, such as ground ball rates, can be expanded to cover the non-PITCHf/x games, too. But I'm not. I'm also collapsing across pitch types due to sample size issues and a lack of finality on many of those classifications.

Anyway, on with the Strasburg. I mean Storen. I mean show.

The minimum pitch total I'm using is 59. Read Hardball Times on Tuesday and you'll figure out why. Hint: Aaron Crow's pitch total.

Notice how well Mejia and Strasburg rank in Whiffs and Ground balls? Storen is all over the place, along with Dunn.
