Timbers at Sounders (U.S. Open Cup match)
Kickoff: 7:30 p.m. Wednesday at Starfire Stadium (capacity 4,500) in Tukwila.
Webcast: Live at timbers.com and soundersfc.com.
At stake: The winner of this elimination match advances to the semifinals of the Lamar Hunt U.S. Open Cup tournament.
Up next: On Aug. 13, the winner will host either the Chicago Fire or the Atlanta Silverbacks in an Open Cup semifinal match.
Format: If Wednesday's match is tied after 90 minutes, an extra 30 minutes will be played. There is no sudden death. If the score is tied after the overtime, penalty kicks will decide the winner.
How they got here: The Timbers advanced by beating the Orlando City under-23s (PDL) at home and then winning at Sporting Kansas City. The Sounders beat the PSA Elite (USASA) 5-0 and the San Jose Earthquakes on penalty kicks, both at Starfire.
Open Cup rivalry: The Sounders are 3-1 all-time against the Timbers in the Open Cup. Portland's win came in 2005 when both were second-division USL clubs. Since joining MLS, Seattle is 3-0 in Cup matches against Portland, including surviving a shootout in Portland in 2010 on the way to the second of Seattle's three Open Cup championships.
Hot foot: Portland's Gaston Fernandez shares the tournament lead with four goals, scoring twice in each of the Timbers' first two tournament games.
Lineup questions: Three wins away from winning the tournament (and a berth in the 2015-16 CONCACAF Champions League tournament), both Seattle and Portland figure to be hungry. But both will be without significant players. The Sounders will be without Clint Dempsey, who is scheduled to appear Wednesday on "The Late Show with David Letterman." Forward Obafemi Martins and defender Djimi Traore are among the hobbled Sounders. In Portland, center backs Pa Modou Kah and Norberto Paparatto, along with forward Maximiliano Urruti remain out. The rivals play again Sunday on national TV, but lineup choices for today figure to be determined by who is healthy rather than to rest anyone for the MLS match.
