It has become somewhat fashionable to micro manage the bull-pen usage in game, sometimes to laughable amounts. The rise of lefty and even righty specialists has augmented the setup and closer defined roles. Some games come to a screeching halt once the bull-pen is brought in with changes happening seemingly after every pitch.
So the questions for your thoughtful consideration are:
1) Is all this bullpen jockying actually producing better results and winning more baseball games? Why or why not?
2) Which strategies, if any, are effective?
3) Which managers seem to have a better grasp of how to manage their bullpens? Are any successful in doing so with consistency (since bullpens are violently inconsistent from year to year consistency with patching together an effective bullpen seems to indicate GM or manager skilz)?
