We have 14 games and 14 2/3 innings' worth of PITCHf/x data on O'Connor. As little as overall performance metrics mean with this kind of sample, individual pitch type metrics mean even less, so I won't spend too much time on that stuff.

- O'Connor's arsenal consists of a tailing fastball, a tight/cutter-ish slider, a curve, and a change that looks similar to his fastball but is 10 mph slower.
- He's been fastball/slider recently. He didn't throw any changeups this year, despite facing righties in 14 of his 29 plate appearances. He only threw two curves.
- He looks like an extreme flyball pitcher. His groundball rate in 105 2006 innings (BIS data) was 36%.
Soft-tosser, lots of walks, lots of flyballs.
