The Orioles will join Major League Baseball tonight to commemorate the 12th anniversary of September 11 by wearing special caps with the American flag for tonight's game against the New York Yankees. The game-worn, autographed and authenticated hats will be auctioned online at www.orioles.com/auction beginning at 7:00 p.m. tonight, with all proceeds to benefit the Frank J. Battaglia Signal 13 Foundation, which provides financial assistance to Baltimore Police Department personnel who suffer extreme personal emergencies. The auction will be open until Wednesday, September 18 at 11:59 p.m. The Orioles will also observe a moment of silence prior to tonight's National Anthem in honor of those who lost their lives on September 11, 2001. In addition the U.S. Army Quartet will sing "God Bless America" during the 7th inning stretch.
