After losing Jonathan Papelbon in free agency, the Boston Red Sox went about the business of finding a closer. They found one in Andrew Bailey.
They only had to wait four months for his Red Sox debut.
The Red Sox acquired Bailey from the Oakland A's along with outfielder Ryan Sweeney, giving up young right fielder Josh Reddick, minor league pitcher Raul Alcantara and minor-league infielder Miles Head in the process.
Bailey, however, underwent thumb surgery to repair his ulnar collateral ligament and didn't make his debut in a Red Sox uniform until Aug. 14.
Sweeney started out on fire for the Sox, hitting .373 in the month of April. However, Sweeney hasn't done much of anything since, hitting .260 for the season with no homers and 16 RBI, currently on the disabled list after breaking his finger punching a door with his throwing hand.
Meanwhile, Reddick has been a power source for the A's, hitting .262 with 28 HR and 73 RBI.
Red Sox Grade: D+. Bailey's thumb injury put the Red Sox in a hole in their bullpen, and Sweeney has largely been a complete bust since his hot start. His inability to control his temper also forced manager Bobby Valentine to use even more players in his outfield.
A's Grade: A-. This was an outstanding trade for Oakland. Reddick has been a key contributor for a team that could be playoff-bound.
