The Orioles have acquired 27-year old lefty swinging 1B Michael Aubrey from the Indians for a player to be named later. Aubrey has played in 61 games in AAA-ball this season and he is 66 for 228 (.289 avg, .760 OPS) with 29 runs scored, 5 homers and 31 RBIs. Aubrey has played in 15 games in his major league career in which he is 9 for 45 (.200 avg, .613 OPS) with 2 runs scored, 2 homers and 3 RBIs. Aubrey used to be a highly thought of prospect in the Indians’ system so he could help the Orioles down the road and the price was right to take a chance on him.

The Orioles will lose starting shortstop Cesar Izturis for the next several weeks due to surgery for an appendicitis. Izturis has played in 45 games for the Orioles this season and he is 39 for 150 (.260 avg, .620 OPS) with 16 runs scored, 1 homer, 13 RBIs and 9 stolen bases. The Orioles will hand the starting job to Robert Andino while Izturis is out of action. Andino has played in 20 games this season for the Orioles and he is 11 for 43 (.256 avg, .577 OPS) with 6 runs scored, 3 RBIs and 1 stolen base. Andino is a good defensive player with a little more power than Izturis but nowhere near his speed.

The Orioles have released lefty reliever Jamie Walker. Walker pitched in 22 games (0 starts) for the Orioles this season and he was 0-0 with a 5.11 ERA and a 1.54 WHIP. The Orioles have recalled lefty reliever Alberto Castillo to replace Walker in the bullpen. He has pitched in 24 games (0 starts) in AAA-ball this season and he is 1-0 with a 3.09 ERA and a 1.24 WHIP. Castillo pitched in 28 games (0 starts) for the Orioles last season and he was 1-0 with a 3.81 ERA and a 1.42 WHIP. This is a win-win situation as Walker should have no problem getting a new job and Castillo should do a decent job for the Orioles.

The Orioles have claimed 25-year old lefty reliever David Davidson off waivers from the Florida Marlins. Davidson only pitched in 1 game for the Marlins this season and it was a disaster. He worked 1 inning for them allowing 4 hits, 4 walks and 5 earned runs. Davidson has also pitched in 13 games (0 starts) in AAA-ball this season and he is 0-1 with a 3.00 ERA and a 1.00 WHIP. Lefties are hard to come by so this was worth the chance for the Orioles.

UPDATE: Davidson has been returned to the Marlins after it was revealed through a physical that he had a shoulder injury.

The Orioles have placed righty starting pitcher Koji Uehara on the 15-day disabled list with a sore hamstring. Uehara has started 9 games this season for the Orioles and he is 2-3 with a 4.09 ERA and a 1.40 WHIP. The Orioles have recalled their #16 rated prospect heading into this season according to Baseball America….right hander David Hernandez who will replace Uehara in the rotation. The 24-year Hernandez has started 8 games in AAA-ball this season and he is 3-1 with a 2.91 ERA and a 1.06 WHIP. He has whiffed 60 batters while only allowing 33 hits in 43 1/3 innings in the minors this year. It’s about time that the Orioles let some of the kids get a chance to show what they can do. They should have done this from the start of the season instead of going with stiffs like Adam Eaton and Mark Hendrickson in the starting rotation.
