The Orioles optioned right-hander Josh Stinson to Triple-A Norfolk after their 3-1 win over the Texas Rangers on Thursday night.
A corresponding roster move will be announced before Friday’s series opener against the Toronto Blue Jays.
Stinson was called up from Norfolk on Wednesday to provide right-handed bullpen depth for left-hander Wei-Yin Chen’s return from the disabled list. Stinson warmed up in the Orioles’ 6-1 win, but he didn’t pitch.
He also wasn't used Thursday.
He now has to stay in the minor leagues for the next 10 days, barring a move involving the disabled list. He’s 4-4 with a 4.23 ERA in 15 starts for Norfolk, where he last pitched July 6.
He has one appearance for the Orioles this year, taking the loss in an April 24 spot start against Toronto.
Manager Buck Showalter likes to keep fresh arms in the bullpen, especially right-handed relievers behind left-handed starters and vice versa. The Orioles have all right-handed starters scheduled until the All-Star break, so the move could involve left-handed relief.
