"Sarfate will throw a bullpen [session] on [Tuesday] and pitch one inning on [Friday] at Triple-A," said Trembley. "Chris Ray will pitch an inning, I believe at [Double-A] Bowie on [Friday]. Those two guys, that's when they're going."
Sarfate, who has been trying to come back from a circulatory problem in his right arm, recently suffered a small setback and could take most of July to return to peak condition. Ray, meanwhile, is working back from a case of tendinitis in his right biceps that has kept Trembley from naming an exact prognosis.
"I couldn't tell you that," Trembley said. "I know earlier this afternoon, [pitching coach Rick] Kranitz was writing out his rehab. All I wanted was the first one to be able to tell you. I don't know anything after that."
The recent acquisition of Cla Meredith will help the Orioles withstand the extended absence of Ray and Sarfate, and Trembley said on Monday that he'd like to get Uehara back in working order as soon as possible. The Orioles want Uehara back for good, though, and they won't push him until they're sure he can handle the strain.
"He's just doing physical therapy work," Trembley said of Uehara, who has a torn flexor tendon in his right arm. "We'll get a better read at him when we come home off this trip, so I couldn't tell you. Obviously, he's going to have to start a throwing program when he gets cleared. I don't know if he's ready to start that yet."
