The Orioles have designated right-hander Asher Wojciechowski for assignment, Roch Kubatko of MASNsports.com reports (via Twitter). The team announced the move shortly thereafter, adding that righties Branden Kline and Evan Phillips are up for Game 1 of Thursday’s doubleheader. Phillips is listed as the 29th man for the day.

It seems Wojciechowski’s 40-man roster spot will go to lefty Bruce Zimmermann. Kubatko tweets that Zimmermann is with the team, and MLB.com’s Joe Trezza reported Wednesday night that Zimmermann was being considered for his MLB debut on Thursday. The Orioles have since announced Zimmerman as the “probable” starter for the second game of Thursday’s twin bill, so a move to formally add him to he roster will be made between the two games.
