Local Kid, probably a Sox fan

Tom Gorzelanny of Evergreen Park is Lefty #3 for the weekend.
He's got plenty of PITCHf/x data, here's the most recent:

8/7 @ari
8/12 @sf
8/22 @col
9/2 @mil
9/12 MIL
9/18 @sd

That home game is the first, and only, PITCHf/x game in Pittsburgh.

Let's see how the six starts compare (y=50)

Looks good enough for today's purposes.

According to ESPN Inside Edge, Gorz throws four pitches:
Fastball, Curve, Slider, Change

Much like Rich Hill, the uses the slider against lefties, and the change against righties, but not as extreme.

The pfx chart looks interesting, using k-means (k=4)
