Carlos Quentin (knee) is back in Friday's lineup against the Diamondbacks.
Quentin hurt his left knee in an awkward slide on Monday and received a cortisone shot on Tuesday. The 30-year-old is hitting just .178 with four homers and a .674 OPS in 30 games this season.
Nationals prospect infielder Anthony Rendon is out of the lineup for Double-A Harrisburg after having his wisdom teeth removed.
He should be good to go in the next day or two. Rendon is hitting .359 (23-for-64) with four homers and a 1.201 OPS since his demotion earlier this month and could be an option with the big club again if Danny Espinosa's wrist injury lingers.
Billy Buckner will start Saturday against the Royals.
Buckner hasn't made an appearance since being called up from Triple-A Salt Lake last week, so he's well rested for the assignment. The 29-year-old has a 6.25 ERA in 21 starts and 15 relief appearances in the majors and can be avoided for fantasy purposes.
Orioles prospect right-hander Dan Klein has been placed on the voluntary retirement list with Double-A Bowie.
Too bad. Klein was a third-round pick out of UCLA in 2010 and posted a 0.93 ERA and 47/7 K/BB ratio over his first 38 2/3 innings in pro ball, but he hasn't pitched since 2011 due to shoulder problems.
Andre Ethier is back in Friday's lineup against the Cardinals.
Ethier was benched Wednesday amid comments from Dodgers manager Don Mattingly that he was looking for the "most competitive lineup" and one that would "fight the hardest." While Either apparently didn't make the cut Wednesday, he's back in there now.
Alfonso Soriano is not in Friday's lineup against the Reds.
He's just getting a breather. Ryan Sweeney will make the start in left field.
Steve Johnson has been scratched from Friday's start with Triple-A Norfolk.
Johnson is healthy, but the Orioles want him available in case they need to add him as a reliever on Saturday. The 25-year-old gave up six runs in four innings in a spot start with the big club earlier this month.
Astros prospect first baseman Jonathan Singleton will join Class A Quad Cities on Monday.
Singleton has served his 50-game suspension for a positive marijuana test and is ready to return to game action. The 21-year-old is one of the top first base prospects in the game and could be on the fast track to the majors before long.
