Judging a Starting Pitcher's Performance: "Stuff" vs. Results

[Thurston Fluff]

Does the BAPIP change in any player without also having other stats change as well?

[logan82]

Yes and no. Obviously if BABIP goes down their slash stats will generally go down. Look Ryan Braun and compare 2007 to 2008. His BABIP dropped way off from .367 to .309 and his LD%, GB% and FB% were almost identical.
