With the semifinals set for Wednesday, September 1, three venues have been named as potential sites for the 2010 Lamar Hunt U.S. Open Cup Final: Qwest Field in Seattle, Wash., RFK Stadium in Washington, D.C. and The Home Depot Center in Carson, California.

Should United defeat Columbus in the first semifinal, the Black-and-Red would either host Chivas USA at 7:30 p.m. ET on Wednesday, Oct. 6 at RFK Stadium, or travel to Qwest Field to face Seattle Sounders FC on Tuesday, Oct. 5 at 11 p.m. ET. The final will be televised live by Fox Soccer Channel.

Last year, D.C. United advanced to the U.S. Open Cup final before falling to Seattle Sounders FC. The Black-and-Red have twice won the tournament, capturing titles in 1996 with a 3-0 win over the Rochester Rhinos and in 2008 courtesy of a 2-1 victory over the Charleston Battery.

United began its title quest this year with play-in victories against MLS rivals FC Dallas and Real Salt Lake, recording 4-2 and 2-1 victories, respectively, to earn third round entry into the Open Cup field. The Black-and-Red have also beaten the Richmond Kickers (USL-2), 2-0, and the Harrisburg City Islanders (USL-2), 2-0 to reach the semifinal stage in this year's event.
