Right-hander David Herndon is reportedly experiencing some lingering discomfort in his pitching elbow and will undergo an MRI.
While the loss of Herndon, in and of itself, isn't a crippling blow, resources are beginning to be stretched in the middle innings. Joe Savery, Michael Schwimer and the forthcoming roster addition - which could be someone off the 40-man roster, like Jake Diekman, or even a rested starting pitcher conditioned to go multiple innings - adds a lot of unproven arms to the mix. Right now, one of the Phils' biggest pressure points is indeed that lack of a swing man, since Kyle Kendrick has moved to the rotation, Michael Stutes is coping with a bum shoulder, you don't really know what you're getting from Jose Contreras, and now this Herndon thing.
The Phils are also sitting on a potentially implosive situation in the eighth inning. The gloss is beginning to fade from Chad Qualls, and Antonio Bastardo is not the same pitcher as last season. Specifically, Qualls is a one-pitch pitcher and Bastardo is just walking way too many guys.
