The A’s have designated 28-year old lefty swinging outfielder Jermaine Mitchell for assignment. Mitchell played in 108 games in AAA-ball for the A’s last year and he was 103 of 409 (.252 avg, .731 OPS) with 75 runs scored, 6 homers, 38 RBIs and 15 stolen bases. He has now played in 753 games in his first seven years in the minors and he is 792 of 2,822 (.281 avg, .803 OPS) with 495 runs scored, 55 homers, 325 RBIs and 144 stolen bases. The A’s aren’t going to miss Mitchell too much moving forward.

UPDATE: (12/1/2012) - The A’s have decided not to tender a contract to Jermaine Mitchell, making him a free agent.

The A’s have acquired 27-year old righty reliever Sandy Rosario from the Red Sox for either a player to be named later or cash considerations. Rosario pitched in 4 games (0 starts) for the Marlins last year and he was 0-0 with a 18.00 ERA and a 2.67 WHIP. He also pitched in 31 games (2 starts) in A+AA+AAA-ball for the Marlins in which he was 0-2 with 17 saves, a 1.99 ERA and a 0.98 WHIP. Rosario has now pitched in 10 games (0 starts) in his first three years in the majors and he is 0-0 with a 15.26 ERA and a 3.26 WHIP. The A’s hope a change of scenery is just what the doctor ordered for Rosario. He will get a shot to win a bullpen job for the A’s next spring.

UPDATE: (12/1/2012) - The A’s have designated Sandy Rosario for assignment.

UPDATE II: (12/7/2012) - The A’s dealt 28-year old righty starting pitcher Graham Godfrey to the Red Sox to complete this deal. Godfrey pitched in 5 games (4 starts) for the A’s last year and he was 0-4 with a 6.43 ERA and a 1.71 WHIP. He pitched in 10 games (8 starts) in his two years with the A’s and he was 1-6 with a 5.09 ERA and a 1.59 WHIP.
