The White Sox shipped Peavy to Boston in a three-team trade involving the Detroit Tigers. The Sox will receive the Tigers' top outfield prospect, Avisail Garcia, and the rest of the deal has also been finalized.
Per the White Sox press release:
The Red Sox get: Peavy from Chicago; right-handed reliever Brayan Villarreal from Detroit
The Tigers get: Shortstop Jose Iglesias from Boston.
So that's a Top 100 prospect from Detroit and three low-level prospects from Boston. Beyond the White Sox, the Red Sox bolster their rotation at the cost of Peavy's contract and an expendable defense-first shortstop, and it appears that the Tigers have a shortstop for if and when the Biogenesis axe drops on Jhonny Peralta.
Garcia has been assigned to Triple-A Charlotte, though he may not stay there for long. The 22-year-old came back from an injury to hit .382/.414/.549 over 152 PA at Triple-A Toledo.
