BALTIMORE -- The Orioles optioned starter Josh Stinson to Triple-A Norfolk following Wednesday's 6-5 loss in 11 innings to Toronto, and the team is expected to add another reliever to help replenish the bullpen in advance of Thursday's series opener in Oakland.
Stinson -- making his debut with Baltimore and the second start of his Major League career -- didn't leave the impression he wanted, surrendering four home runs -- and five runs total -- over 5 2/3 innings.
"I was hoping Josh would pitch real well and get us deep, and he actually did give us a chance," manager Buck Showalter said of the 76-pitch outing. "He got us into some innings that we could manage out of the bullpen."
Still, the O's relief corps picked up 5 1/3 innings after Stinson and pitched 34 innings over the nine-game homestand. The team will add a pitcher from Triple-A Norfolk to make sure it is covered. Baltimore won't need an additional starter until Monday's series opener in Seattle.
Stinson, who was claimed on waivers from Oakland earlier in the month, had nearly been promoted over the weekend as an extra bullpen arm. But the O's chose to hold off, and he made an appearance for Class A Frederick to stay fresh before getting the call for Wednesday's start, which was necessary due to Friday's rainout and the team opting not to pitch Jason Hammel or Wei-Yin Chen on short rest.
