An MRI performed on Dickerson's hamstring revealed a small tear, Orioles manager Buck Showalter said.
“He felt decent in Tampa, I felt like he could play defense for a few innings, but not hit and run,” he said. “I haven’t had him for the last two or three days. ... I think he’s probably done.”
Casilla, who came out of Monday’s game after hitting his head on Nick Markakis’ thigh while attempting a diving catch, injured his thumb on the same play. As much as the Orioles have concern over Casilla’s lingering concussion symptoms, the thumb will also keep him out.
“It’s the thumb as much as anything,” Showalter said. “Looking back on that, he was actually lucky. So was Nick. But he’s feeling a little bit better head-wise, but I don’t think you’re going to see him play.”
Dickerson spent most of the season with the Orioles after he was called up from Triple-A Norfolk on April 10. He hit .238/.266/.400 with four homers, 13 RBIs and five stolen bases in six attempts over 56 games. Dickerson's walk-off, three-run homer with two outs in the bottom of the ninth inning in a 7-5 victory over the Detroit Tigers on May 31 gave the Orioles one of their most improbable wins of the season.
Casilla had nine steals in 11 attempts and recorded a .214/.268./295 slash line in 62 games.
Pridie has whirlwind return to majors
Outfielder Jason Pridie had just returned home to Arizona on Tuesday evening when he received a call from the Orioles telling him the team was selecting his contract.
Pridie, who was named an International League All-Star and hit .269/.333/.434 with 15 homers and 57 RBIs for Triple-A Norfolk, flew from Phoenix to Baltimore early Wednesday morning and was the starting center fielder against the Blue Jays that night, going 1-for-4 in his Orioles debut.
Since the end of the Triple-A season, Pridie had been working out in Sarasota, Fla., awaiting a possible call-up.
"Obviously, it happened later than I thought it was going to, but here I am," Pridie said. "That's the goal. Five [games] is better than none. I'd rather be here than home in Arizona. It was tough at times off the field, but on the field, you have to play the game and be a professional."
Pridie started in left field Thursday against Toronto.
Showalter pondering coaching staff for 2014
Showalter said he expects his coaching staff to stay mostly intact for next season.
"I think you know my history and track record with coaches," Showalter said. "We'll listen to what everyone has to say. … I want to make sure they want to come back, too. We have some of them contractually obligated in a good way. We're pretty excited about that."
The main question mark is the pitching coach position. Rick Adair took personal leave Aug. 15 and was replaced by bullpen coach bullpen coach Bill Castro.
Showalter said he plans to meet with Adair, whose father died last week, to catch up with him and discuss his role on next year's staff.
Around the horn
First baseman Chris Davis, who was the designated hitter Wednesday, sat out Thursday’s game with a sore right foot. Showalter said he is day-to-day. "[We will] see how he feels in the morning,” Showalter said. "He did tell me in the eighth or ninth inning that this sitting stuff, he didn't like it too much." … Second baseman Jonathan Schoop's third-inning throwing error Thursday was the Orioles' 51st of the season, the fewest in the majors. … Left-handed reliever T.J. McFarland left the team this morning to attend to a family situation back home in suburban Chicago. He was expected to return in time for tonight's game, but Showalter said he planned to play without McFarland. … The Orioles still haven't decided whether right-hander Chris Tillman will start in Sunday's season finale. The Red Sox are still fighting for the American League's top record and No. 1 playoff seed, and Showalter said he's weighed the possible importance of that game. Meanwhile, Tillman said he will go through his normal routine as if he's starting Sunday. Another factor is whether right-hander Jason Hammel can come back on three days' rest. He closed out Wednesday's win with 2 1/3 relief innings.

Nick Markakis RF
Danny Valencia 3B
