OAKLAND -- Orioles pitcher Chris Tillman is in line to start Monday's series opener in Seattle, which will mark his first start since exiting the Sept. 2 game in New York with right elbow discomfort.
Tillman threw a side session on Thursday in Baltimore -- his second since being diagnosed with right elbow inflammation -- and said it went well, but the organization is being cautious with the 24-year-old righty.
"I think he's going to have one more [side] just to make sure it doesn't flare up," manager Buck Showalter said of Tillman. "That gives us a good feeling about where he is and I think Monday will be a good spot for him."
Sunday's starter is still undecided, as is a pitcher for Tuesday, with Joe Saunders -- Friday's starter -- slated to pitch Wednesday's game. Sunday's start could be one of several different guys, according to Showalter, with Jake Arrieta, Randy Wolf, Steve Johnson and Tommy Hunter all possible options.
Wolf is believed to be the leading candidate to make that start if he's not needed out of the bullpen in the next two games.
Betemit's wrist injury may end his season
OAKLAND -- Orioles infielder/designated hitter Wilson Betemit is likely done for the year after reaggravating a right wrist injury prior to Friday's game in Oakland.
"I am really frustrated," said Betemit, who returned from the disabled list Sept. 1 after missing 2 1/2 weeks with a right wrist injury. "I come back from the DL, and I try to contribute to the team, but that happens.
"It's frustrating. Everything is going good for us, and this happens to me. We'll see what happens. I am going to Sarasota, [Fla.], and we'll see Monday [what] they tell me."
Betemit said he hit in the cages as usual on Friday afternoon and his wrist was pretty sore. After the first round of outdoor pregame batting practice, he started experiencing discomfort in his wrist, the same kind of symptoms he had experienced before.
"He's really down," manager Buck Showalter said of Betemit, who was unavailable off the bench in the Orioles' 3-2 loss to the A's. "He battled his way back and is a big part of what we've done here. But I don't like our prospects of getting him back."
Betemit hit .261 with a .332 on-base percentage and a .422 slugging percentage in 102 games and will fly to the team's spring home on Sunday and see a hand specialist for further examination on Monday.
Asked if he might have had his final at-bat this season for the Orioles, Betemit said, "I don't know. I'll have to wait for what they tell me Monday, what I have to do and what they are going to do for me."
Rehab progressing for Patton, Thome
OAKLAND -- Reliever Troy Patton (right ankle sprain) is slated to throw off a mound Sunday in a rehab game at the Orioles' fall instructional league in Sarasota, Fla., and could rejoin the team for next week's series in Seattle.
In a perfect world, the Orioles would like Patton, who last pitched in a big league game Aug. 12, to make back-to-back appearances and be stretched out to go more than an inning, but manager Buck Showalter said they will wait and see how Sunday goes before mapping out a schedule.
"We are hoping at the worst we get him in Boston [next weekend]," he said of Patton. "And Jimmy [Thome] hopefully right behind him."
Thome, who has been rehabbing back from a herniated disk in his neck, is hoping to bat Monday or Wednesday in the instructional games.
"They were part of some good things that we'd like to take advantage of again," Showalter said of the possibility of having Patton and Thome back. "So, it would help anytime. But this time of year, it's as many bullets as you can arm yourself with. It'd be two guys we know are capable of helping us."
All full-time Oriole employees, which is approximately 90 people, and 11 players are participating in a ticket giveaway around Baltimore where fans who are showing their support with team gear will be randomly awarded free tickets for the team's upcoming homestand.
Each participant will be given six tickets to give away as part of the Orioles' random acts of kindness promotion and can be found anywhere in and around the city at places like grocery stores and gas stations.
Kevin Gregg was released by the organization on Friday, meaning he is free to sign anywhere. Ryan Adams, who was also taken off the 40-man roster, was outrighted to Triple-A Norfolk.
Two O's Minor Leaguers are participating in the World Baseball Classic qualifying games: Robbie Widlansky for Israel and Steven Bumbry for England.
Major League Baseball removed an error from Orioles first baseman Mark Reynolds from Sept. 9 against the Yankees. Robinson Cano's ball down the right-field line in the top of the eighth inning was changed to a double.
