Re: You are the manager...
Bring in Coffey and PH for him in the bottom of the inning. He's the best bet against 2 right handers with power given his decent K rate and strong ground ball tendencies. A double play ball is ideal here and Stormy is just a touch homer prone. Saarloos is option #2 if Coffey is unavailable.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
