According to Jayson Stark, at least.
I know Sabean has said he's not interested in rentals (and I happen to agree) but I think that we should absolutely make an exception here. Werth shouldn't be all the expensive (in terms of prospects) to obtain, since the Phillies want to dump salary and have a replacement from the minors waiting, and Werth is a guaranteed Type-A, so, hey, free draft picks.
GIT R DONE SABES. It makes too much sense not to.
