Randy Wolf played long toss before the game, and Showalter said if everything checks out physically, the Orioles would likely activate Wolf on Friday. Wolf will wear No. 28.
To make room for Wolf's expected activation to the 25-man roster, the Orioles sent left-hander Zach Britton to Triple-A Norfolk after Thursday's game. Britton, who struck out a career-high 10 in his eight-inning outing, is expected to return when rosters expand on Saturday.
Showalter said Nick Johnson (wrist) is still struggling and doesn't appear to have made much improvement in recent days.
Tommy Hunter will pitch one inning at Double-A Bowie on Saturday and will be available to return to the Orioles on Monday.
