The Orioles placed struggling reliever Chaz Roe on the 15-day disabled list with right shoulder tendinitis just before Monday's series opener against the Seattle Mariners and recalled right-handed pitcher Mychal Givens from Double-A Bowie to take his place in the Orioles bullpen.
Roe, who was the losing pitcher in the Orioles' 5-4 loss to the Los Angeles Angels on Sunday after yielding a leadoff double in the 11th inning, traveled back East on Monday morning to be evaluated by team doctors. Givens joined the team in Seattle Monday.
Tests on Roe's shoulder showed no structural damage. He would be eligible to return from the disabled list on Aug. 25.
One of the team's feel-good stories of the season, Roe emerged from being a nonroster spring invitee to earning a key role in the Orioles bullpen, but the 28-year-old has struggled of late.
After the Orioles selected Roe's contract from Triple-A Norfolk on May 24, he began his Orioles career with 91/3 scoreless innings and posted a 0.90 ERA over his first 15 appearances, covering 20 innings. But over his last 13 appearances, Roe owns a 6.14 ERA and opponents are batting .365 against him.
"I don't think there's anything wrong with him structurally," Orioles manager Buck Showalter said. "It's just that major league innings are a lot more stressful than minor league innings. Every pitch is top torque or whatever, but he's been a healthy guy his whole career. He's never really had any problems. That was one of the allures of signing him.
"He is only 28 and he's been pitching very good innings for us," Showalter added. "At times of late it felt like the ball wasn't coming out like it was [before]. You hear about it a lot. In spring training, they call it a dead arm period."
Placing Roe on the DL gives the Orioles flexibility in their bullpen. Since activating Rule 5 pick Jason Garcia from the DL on Thursday, the Orioles had just one reliever whom they could send to the minor leagues, T.J. McFarland. With Givens back in the fold, they have two.
Givens, a converted shortstop with an unconventional sidearm delivery, hasn't allowed a run in four major league relief innings. He has allowed just one hit and has struck out six batters while walking none.
"I got the call last night so I just packed up and got ready for the game today," Givens said. "I'm happy with my results and I'm happy with what I've done, but I still have a lot of work to do and I'm a long way from being the guy. So I'm trying to learn from the best of them like [Darren] O'Day and Zach Britton, all the guys in the bullpen, take in all their information to make myself better."
