After dealing with a short start and taxing their bullpen Sunday in Toronto, right-hander Odrisamer Despaigne joined the Orioles from Triple-A Norfolk on Tuesday in Boston.
In a possible indication of what his role will be, Despaigne took the roster spot of right-hander Vance Worley, who was serving primarily as the team's long reliever but suffered a groin strain early in his 4 1/3-inning relief appearance Sunday. Worley, who is 2-0 with a 2.66 ERA in 40 2/3 innings, went on the disabled list retroactive to Monday.
Worley said he felt the injury for the first time in the second inning during an at-bat against outfielder Michael Saunders, but was able to pitch through it.
"I went out there and just made sure I kept the ball down in the zone," Worley said. "The one pitch I got hurt on was the home run. Aside from that, everything else did what I wanted it to do, and I made the pitches where I wanted them."
Worley said he has never dealt with a similar groin injury, and as such doesn't know what the recovery will be like. But he said the 15-day window might be all he needs.
"It's already a lot better than what it was," Worley said. "I don't know if it was just maybe a tall mound, or I wasn't as hydrated as I should have been, but I definitely felt like I was stretched out enough where I could go out there and compete. But I think 15 days is pretty reasonable."
Manager Buck Showalter said the unknown of the injury was what made it worth having him on the disabled list.
"I think Vance will be ready before the 15 days," Showalter said. "The problem is he's never had a leg issue before, and we just don't have any history to go on. He couldn't pitch today, and we didn't want to lose the backdate days. There were a lot of different ways we could have done it. He's having a good year. He's a big part of the bullpen. The problem is, say it's six days from now, you still don't know what happens when he pitches. It's another 10 to 20 percent when a guy pitches that you go at. Throwing on the side, could you imagine Sunday if we had brought him in at the end of this period and he had a problem with it? Paul Janish is pitching in the third inning. We'll clean it up, and he'll be pitching for the last 87, 88 games we have hopefully."
Despaigne, 29, joins the Orioles for the first time since being acquired this past offseason from the San Diego Padres after making 50 major league appearances (34 starts) from 2014 to 2015. He has spent the season with Triple-A Norfolk, going 1-6 with a 3.59 ERA, but has been especially good lately.
Despiagne has allowed five runs in 27 2/3 innings over his past five starts for a 1.63 ERA. He has struck out 23 and walked eight during that time.
He last pitched on June 8, throwing six innings of four-hit, scoreless ball with five strikeouts and three walks.
"He's going to be in the bullpen tonight," Showalter said. "He's had four or five days off. We need that length with Worley gone. We are always going to have to cover ouserlves. Talking to [Norfolk manager Ron Johnson] and everybody down there, [director of player development] Brian Graham, [says] he's the best we have for our need down there. He's been throwing the ball real well."
