The Orioles' bullpen shuffle continued Wednesday when they summoned left-hander Ashur Tolliver from Triple-A Norfolk and placed left-hander Brian Duensing on the disabled list with elbow inflammation.
Duensing said that he'll have surgery on Friday to remove a pair of cartilage chips in his left elbow, which caused inflammation in a bizarre fashion on Monday as he sat in the bullpen during the game in Texas.
He played catch before the game, and said he didn't have any issues, but instead suffered his injury in one of the Adirondack chairs in the Rangers' visiting bullpen.
"To be honest, I just kind of rolled over on the chair, I just kind of rolled over and felt something kind of weird and next thing I know, it's swollen and couldn't move it," Duensing said. "So, I was in the training room, and I didn't even really do anything. That's kind of also disappointing — a little freaky. I haven't had any arm problems whatsoever since I had Tommy John in 2004, so for it to just kind of pop up like that just kind of seems a little out of the ordinary, but not much I can do about it other than take care of it and move on."
Duensing said the elbow was structurally sound, according to scans, so the rehab process won't be as arduous as it would be rehabbing ligament or tendon damage. He said the chips are around the back of his elbow, where the triceps connect, and are limiting his range of motion and creating tightness.
He was given a timetable of returning of about 4-8 weeks, he said, and set a rough target of Aug. 1 for a comeback
"It's not too painful, it just kind of feels like there's a lot of pressure there," Duensing said. "I'm going to try to get it taken care of get it fixed, and be back in time to try and win the division."
Duensing had allowed four runs in 6 2/3 innings over seven appearances with the Orioles, who signed him to a minor league contract in mid-May and added him to the active roster a week later.
Tolliver, 28, debuted with the Orioles last month in Houston and appeared in four games, allowing three earned runs in four innings. He made five appearances since being optioned back to Triple-A Norfolk. The first four were scoreless and the fifth, which came Sunday, was a 1 1/3-inning outing in which he allowed two runs.
Manager Buck Showalter said he was added back to the roster because he's "rested, ready to pitch, and doing OK down there."
"I'm really happy to be here," Tolliver said. "I'm feeling good, just continuing to work with the staff down there. Everything's going good."
The bullpen has been under particular duress in recent days. With top set-up man Darren O'Day (hamstring) and long reliever Vance Worley (groin) on the disabled list, the Orioles have been stretched thin. They've also had to carry Wednesday's starter, Ubaldo Jimenez, in the bullpen.
