In exchange for Buchholz, the Red Sox have received minor league second baseman Josh Tobias. In the trade, the Phillies will be picking up all of Buchholz's remaining salary.
The deal provides Phiadelphia some much-needed rotation depth in the transition period between rebuilding and contention. Buchholz is signed through just 2017, but he should be a nice bridge to the top prospects coming up the pipeline.
And if Buchholz can return to old form, he could provide some major upside in Philadelphia, who may decide to keep him like they did with Jeremy Hellickson over the past calendar year.
