TUKWILA, Wash. — The Seattle Sounders have won the U.S. Open Cup four times, as many as any team during the MLS era and just one shy of the all-time record. Since 2009, they’ve accumulated a 23-6-5 record in the tournament, easily the best winning percentage. That includes a 19-2-2 record at home and a 17-1-1 record at Starfire Stadium.
But their recent history is not nearly as impressive. The Sounders last won an Open Cup match in 2017, when they beat the Portland Timbers in the fourth round before being bounced by the San Jose Earthquakes a round later.
