Can anyone explain baseball pitching strategies?

Didn't take long to get me to post an "I told you so" post, but last night's Yankee debacle from manager Boone gives me the right to say "I told you so."

That douche Yankee manager Boone followed the book. Pre-planned and written out before the game was even played. He pulled pitchers who were doing perfect work just because the book tells him to bring in another guy. He literally brought in ten pitchers. Kept bringing them in until he found one to lose the game. That last sentence sounds strange but it's true. Ten pitchers. Nine were spectacular. But Boone kept going to his bullpen until he found one that sucked and who would lose the game. Baseball is so f***ed up these days. I hate it.
