Rookie Kevin Gausman, who started the game, was optioned to Norfolk afterward. That set up the move to recall Arrieta on Friday.
Manager Buck Showalter said Friday, "If we would have played a nine-inning game, Gausman would have stayed."
This is the third stint with Baltimore this season for Arrieta, who began the season in the starting rotation. He's 1-1 with a 6.63 ERA in four appearances, all of them starts.
Showalter says Gausman could return sooner than 10 days if Orioles starter Miguel Gonzalez goes on paternity leave.
