I think pitchers get away with a lot more "mistake" pitches than people acknowledge. I've seen plenty of smashable pitches go by. Two pitches, they both hang in the zone. On one the batter doesn't swing because he's sitting dead red. On the other he knocks it out of the park. The pitcher didn't do anything better or worse on either pitch (assuming he didn't tip on one). A lot of pitches that get too much of the plate and are critiqued by analysts are the same exact pitch that earlier got a guy out. Not all big hits come off mistakes, and not all "mistakes" turn into big hits. Doesn't that add validity to the great pitchers though? If more hittable pitches go by than most expect, wouldn't that also include even the best hitters hitting a pitcher's pitch. If Lidge throws 2 more sliders like he did with the 1st pitch, Houston is getting ready to play game 1 of the WS, instead of game 6 of the NLCS. No, because Pujols can choose not to swing at them. An AB is like a dance between the pitcher and hitter, with both playing an equal role. Nothing that one of them does has any meaning independent of what the other did. He could have chosen to not swing at the 1st pitch, but he did and missed pretty badly b/c of the quality of the pitch rather than an error by the hitter who is the best one in MLB. The hitter is always in a defensive mode, even 2-0, 3-0, he might have certain advantages but is in a mode of defense. Whether it is fear or depending on the actions of the pitcher. The more fear, the more defensive he becomes.
