don't worry guys, Charlie Manuel cleared it up for us:
"Tonight, [Werth] is our centerfielder," Manuel said. "Victorino is still going to play centerfield and he's still kind of our centerfielder. At the same time, Werth's our centerfielder tonight, if that makes sense. For me to say no, Victorino is not going to play centerfield for us anymore, I'm not going to say that, because that's not true."
So basically Charlie is riding the hot hand unitl "something" happens. Looks very similar to the Dodger OF situation, at least in the short term. I have not activated Victorino from the DL yet and will let him sit there until something sorts itself out.
