BALTIMORE -- After waiting more than two hours to see if the weather would relent, Sunday afternoon's game between the Orioles and Toronto Blue Jays was postponed.

The two teams will now play a single-admission doubleheader in Baltimore on Monday, Sept. 24, beginning at 4:05 p.m. ET, with all gates opening at 3 p.m. The second game will not start before 7:05 p.m.

Sunday's originally scheduled starter, Chris Tillman, was pushed back to Tuesday, with Wei-Yin Chen making Monday's start against the White Sox as planned.

Tickets for Sunday's game may be exchanged for seats of equal value for the Sept. 24 doubleheader or any remaining non-prime home game during the 2012 season, subject to availability. Ticket exchanges must be made by Sept. 26.

Tickets for the Sept. 24 game will be valid for both games of the doubleheader. Ticket exchanges can be performed at the box office or submitted in writing along with the original tickets and mailed via certified mail by Sept. 26 to: Baltimore Orioles, Attention: August 26 Rainout, 333 West Camden Street, Baltimore, MD 21201.
