The A's announced that they traded minor league right-hander Graham Godfrey to the Red Sox. Godfrey serves as the player to be named later from the November deal that sent Sandy Rosario to Oakland.

Godfrey, 28, started four games for the A's early on in the 2012 season. He spent most of this past season at Triple-A, where he posted a 3.29 ERA with 5.2 K/9 and 2.2 BB/9 in 104 innings. In parts of two seasons at the MLB level, Godfrey has a 5.09 ERA with 4.5 K/9 and 2.9 BB/9 in 46 innings.

The A's designated Rosario for assignment two days after acquiring him.
