Craig Hansen's day

For some insane reason, I decided to go look up Craig Hansen's PitchFX from his outing today. I was mostly interested in his control for obvious reasons. For a second, I thought I was on to something. The location graph from his at-bat against Wilkin Castillo is interesting:

Could that be right? Was Hansen getting squeezed by the umps? The next two batters, Corey Patterson and Chris Dickerson, singled and bunted on the first pitch. Both pitches were strikes. The last batter he faced was Jeff Keppinger. Was he squeezed against Keppinger, too?

Uh, that's a big no. Let's play a fun game: can you find the fourth dot on the graph?
