Orioles Notebook: Chen to throw half-mound session

BALTIMORE - Starting pitcher Wei-Yin Chen is scheduled to throw a half-mound session Thursday in Sarasota, Fla., manager Buck Showalter said, and he could move up to a full-sized mound outing Saturday as the Baltimore Orioles' left-hander continues his rehabilitation from a strained oblique muscle.

Chen, 27, has been on the disabled list since May 14, two days after suffering the injury during a start in Minnesota. He beat the Twins 6-0 and improved to 3-3 (3.04 ERA) with that outing.

Second baseman Brian Roberts (hamstring) took some indoor batting practice Wednesday, Showalter said, and both he and left fielder Nolan Reimold (hamstring) will be with organizational hitting coach Terry Crowley when they make their rehab assignments.

"One of the main things he does for us," Showalter said about Crowley, "is he lets us know when they're ready. He's got a grip on what they've got to do to be ready. He really helps us with position players."

Showalter hinted that Reimold may be a bit further along than Roberts with his progress, but he wouldn't say where either player would be when they're ready for their minor-league stint.

Showalter said infielder/designated hitter Wilson Betemit recently began taking grounders in Sarasota. Betemit has been out since spring training with a knee injury but could be ready to come off the disabled list in about a month.

STREAK SNAPPER: Left fielder Nate McLouth had his consecutive stolen base streak halted at 19 when he was caught stealing in the third inning Wednesday. McLouth slid in safely but his leg came off the bag and Angels shortstop Erick Aybar applied the tag. McLouth and Showalter argued the call, to no avail, with umpire Joe West.

McLouth went 2 for 5 and has reached base safely in 18 of his last 21 games. His run of steals is the third longest in club history.

NICK THE STICK: Right fielder Nick Markakis collected his 12th go-ahead RBI of the year with a run-scoring single in the first, and he's one of four Orioles with 10 or more this season. Adam Jones has 12, Chris Davis has 10 and Manny Machado has 10 to join Markakis.

TAKIN' IT TO THE STREET: Angels catcher Hank Conger's solo homer in the third inning became the 69th in Camden Yards history to land on Eutaw Street, but only the second from a Los Angeles player. Lee Stevens was the first back on May 23, 1992, the third in ballpark's 22-year history.

UP NEXT: The Orioles host AL East-leading Boston in a four-game series starting Thursday. The Red Sox have their first three starters lined up in Felix Doubront, Ryan Dempster and John Lackey, with Sunday's spot to be determined. Baltimore lists Kevin Gausman, Chris Tillman, Freddy Garcia and Miguel Gonzalez as its starters, but Gonzalez is subject to change with his wife about to give birth.
