Pitcher Efficiency

Based on last night's recap, in which we figured out that Felipe Paulino has to throw 4.48 pitches per out, I got curious. This was wrong. I can't add past 10pm, apparently. This table is correct. This, inevitably, leads to tables. And now that we've gone through the rotation three times, let's take a gander at the efficiency of the rotation so far.

An explanation:
Pitches = Number of pitches thrown
Strikes = Seriously?
P/O = Pitches per out
P/PA = Pitches per plate appearance
PA/K = Plate appearances per strikeout

Astros Pitcher Efficiency

Name	Pitches	Strikes	P/O	P/PA	PA/K
Oswalt	302	196	5.30	3.97	4.47
Wandy	266	161	4.59	3.55	10.7
Myers	317	212	5.28	3.73	7.08
Norris	274	160	7.21	4.49	3.59
Paulino	324	191	6.48	4.32	6.82

A couple of things here. While Bud Norris has the highest pitch/plate appearance ratio, he has the lowest plate appearance/strikeout ratio. Wandy has the lowest pitch per plate appearance ratio, but isn't striking anybody out.
