Orioles reliever Darren O'Day was supposed to take a bullpen session on his way back from a hyperextended right elbow Wednesday, but didn't feel up to it after a light catch Tuesday, manager Buck Showalter said.
Showalter said the team has recently been looking at former Seattle Mariners reliever Tom Wilhelmsen as a possible example of the recovery period required. He suffered a similar injury in a similar manner in 2015, and missed from April 11 to May 8 of that year.
"He was like three or four weeks," Showalter said. "It's just slow. It's slow."
With the team heading to face the Tampa Bay Rays this weekend in Florida, Showalter said head athletic trainer Brian Ebel was discussing alternative treatments or tests that could occur when they're around familiar doctors near their spring training home in Sarasota, Fla.
"We'll see what that brings," Showalter said. "I'm hoping he feels good tomorrow. I think when it happens, it'll be kind of like an oblique. It's going to be gone one day and it goes fast. But it's not going real well."
O'Day went on the disabled list retroactive to May 6 after he banged into someone with his low arm swing in the bullpen warming up. He said at the time it was a freak incident and tests revealed it to be structurally sound. Showalter said the team hoped to have him back right around the 10-day window for his activation, but that passed a week ago.
Castro start will wait
As interested in seeing right-hander Miguel Castro as a starter as the Orioles are, Showalter said it's hard to imagine the team not using him in relief before a starter is needed Friday.
Castro pitched to one batter Tuesday, and with Mychal Givens and possibly Richard Bleier to be held out Wednesday, the idea of keeping David Hess in the rotation with Castro always in reserve seems to be the Orioles' most likely course.
"It's a little bit of a stretch, but I think he could appear in multiple innings," Showalter said. "It's hard to think that we could get through the next two days without using him. I'm not going to use Mike tonight, obviously, and we'll see where we are with Richard when he gets through throwing. But Richard hasn't thrown too many pitches. Both those guys, sometimes they want to be used more than they are. ... It's been a challenge to pass the load around, and guys like Miguel allow us to do that."
Castro was supposed to start May 16 against the Philadelphia Phillies, but a rainout the night before caused the Orioles to adjust their plans.
Around the horn
Showalter said Zach Britton (Achilles) felt good after Tuesday's simulated game in Chicago. He's scheduled to be back on the mound Saturday in Florida. ... Left-hander Zac Lowther struck out 10 in six scoreless, one-hit innings for Low-A Delmarva on Wednesday, his third double-digit strikeout game in six starts for the Shorebirds.
