Dickerson, Casilla likely done for season

BALTIMORE -- Chris Dickerson and Alexi Casilla are both likely done for the rest of the season, with Dickerson dealing with a right hamstring injury and Casilla injured in a collision on Monday against the Rays.

Orioles manager Buck Showalter said Dickerson -- who had an MRI that revealed a slight tear -- hasn't been available for a while, particularly as a hitter. Dickerson has opted to stay with the team through Sunday's regular season finale and Casilla is also expected to hang around.

Casilla's injury is two-fold, with concussion-like symptoms after his collision with Nick Markakis and a right thumb sprain also sustained on the play. Casilla hit .214 in 62 games, while Dickerson appeared in 56 games and hit .238.

Showalter hopes coaching staff returns in '14

BALTIMORE -- If it's up to Orioles manager Buck Showalter, his coaching staff will stay intact in 2014.

"I think you know with my history and track record with coaches more than likely how that ends up, but we'll listen to what everybody's got to say," Showalter said. "I'll let everything kind of clear and make sure they want to be back. We've got some of them contractually obligated anyway [for next year], in a good way. I'm pretty excited about that."

Showalter will meet with Rick Adair when Adair is in town next week. The O's skipper said it will be more of a get-together "as a friend," although he will see where the former pitching coach -- who took a personal leave of absence in August -- stands in regards to 2014.

If Adair does return, would Billy Castro move back to his previous role as bullpen coach, which is currently being held by Scott McGregor?

"Everything's open. We'll see where everybody is in their life right now," Showalter said. "Scotty's done a good job for us."
