Rosario was acquired by the A's on Nov. 28 for a player to be named later.
The Oakland Athletics have sent pitcher Graham Godfrey to the Boston Red Sox to complete the deal the two clubs agreed to on Nov. 28. The A's originally received Sandy Rosario in exchange for a player to be named later.
Godfrey began the 2012 season with Oakland and had two stints with the A's, posting a 0-4 record and a 6.43 ERA in five games. He tossed a total of 21 innings at the Major League level, and after continued struggles, he was sent down to Triple-A. The 28-year-old pitcher regained his success with Sacramento, posting a 3.29 ERA and 11-2 record over 104 innings on the mound. He made a total of 20 appearances, including 17 starts.
Rosario posted a 1.04 ERA and 16 saves in 25 relief appearances this past season with the Marlins Triple-A affiliate. Rosario also logged an 18.00 ERA in four relief appearances with the Marlins. He was designated for assignment Nov. 30 when the A's acquired Chris Resop from Pittsburgh.
