Orioles manager Buck Showalter made it clear to say that set-up man Darren O'Day has not suffered a setback in his recovery from a right hamstring strain following his bullpen session Tuesday, but the team's timetable for O'Day's return from the disabled list might be slowed.
O'Day threw his second full bullpen session before Tuesday's game -- he threw his first between games of Saturday's doubleheader -- and Showalter said that O'Day session "wasn't quite as good as we hoped it would be."
"It's slow," Showalter said. "We said at the time, when you get that high hamstring, especially with his delivery, how he's got to get down on that leg, it's slow. No setback or anything. It just didn't move forward much."
Before the Orioles headed out west, the club hoped that O'Day could throw his second bullpen session Tuesday and then progress to pitch in two simulated game outings, his final step before returning from the DL. Now, Showalter said O'Day might need one more bullpen session before moving to sim games.
"I don't know yet," Showalter said. "We'll see how tomorrow comes. He may take another side. He needs to repeat that good side he had the other day before we go into that sim game."
O'Day hasn't pitched since June 1, pushing right-handers Brad Brach and Mychal Givens into more set-up role situations.
Other pregame notes:
-- Right-hander Vance Worley, making his second minor league rehab appearance at high Class-A Frederick on Tuesday, threw three perfect innings, striking out two on 31 pitches (21 strikes).
"He threw well. It went real well today statistically," Showalter said. "I don't know what the people watching him are going to say, but we'll see."
-- Catcher Caleb Joseph made his second start at catcher for Frederick on Tuesday. Joseph just received clearance to catch in games on Tuesday after going on the DL for testicular surgery. Showalter had hoped Joseph would be able to be available for Wednesday's game in San Diego, but now won't join the team until their four-game series in Seattle starting Thursday at the earliest.
"I was hoping [he'd only need one game]," Showalter said. "I think they think he needs more. … They're watching him. I talked to Caleb some yesterday. He felt great. Caught eight innings. See how he feels today. He might be a little sore. But he's been catching in the bullpen for quite a while. He's got almost 30 plate appearances, so we'll see."
-- Wounded U.S. Marine Kirstie Ennis was a guest of Showalter and his wife Angela during batting practice on Tuesday. Ennis, who is from the same Pensacola, Fla. area as Showalter, was wounded in 2012 serving in Afghanistan following a helicopter crash.
She suffered injuries to her jaw, legs, arms, brain and spinal cord. Ennis had her left leg amputated and is recovering at the Naval Medical Center in San Diego, but is on track to compete in the 2018 Paralympics as a snowboarder.
