Watching C.J. Wilson last night, you got the feeling that he had more of a game plan and, even better, that it worked. He was efficient and was overpowering when he needed to be. Looking a little deeper at his start, it becomes pretty apparent that those impressions were correct.
First off, look at these graphs showing CJ's pitch selection against righties against Boston (a good start in itself) and against the Angels:

Looking at these, a couple things about his last start are pretty apparent. First, he almost exclusively worked the outside of the plate, very rarely coming inside on righties. Second, he heavily favored his cutter, throwing it 56% of the time. This is quite a departure from his season percentage of 18.9%. Overall, this approach here seemed to lead to pitches that, while in the strike zone, were hard to make good contact against.
Given that he threw 13 pitches to lefties in each of his last two starts, I'm hesitant to make many observations about it, but it's notable that he eschews his cutter in favor of the two-seam (which stands to reason, since it will break into the hitter's hands). Given his results against left-handed hitters, (.090/.157/.120), I won't second guess this approach.
His previous struggles against right-handed hitters (.235/.344/.346), however, were cause for concern. We all know that C.J. is an intelligent guy and is, by all accounts, a hard worker, and it appears that his new approach against RHBs has found some success (albeit in a small sample size). It's even more encouraging to think that watching Cliff Lee caused this change in Lee, if only for what it might mean to the rest of the rotation.
In conclusion, I guess I'd say I really, really liked what I saw from Christopher John Wilson last night.
