CHICAGO (AP) - The game between the Baltimore Orioles and Chicago White Sox on Tuesday night was postponed because of rain several hours before it was scheduled to begin.
They will play a traditional doubleheader Wednesday starting at 3:10 p.m. local time.
The White Sox have won four in a row. Last-place Baltimore has lost four straight.
Chicago's Carlos Rodón and Baltimore's David Hess are scheduled to start Game 1, with Ivan Nova and Andrew Cashner going Game 2 after having their turns pushed back a day.
The Orioles added right-hander Shawn Armstrong to their 25-man roster. He replaced left-hander Tanner Scott, who was optioned to Triple-A Norfolk on Monday night.
Armstrong was claimed off waivers from the Seattle Mariners on Sunday. He had a 0-1 record and 14.73 ERA in four relief appearances.
