SEATTLE -- Carlo Ruiz scored 58 seconds into the first overtime on Tuesday night, helping send FC Dallas into the U.S. Open Cup finals with a 2-1 victory over the Seattle Sounders.
Abe Thompson converted a penalty kick with a minute and a half left in the second overtime period to clinch the game for Dallas after Dax McCarty was taken down in the penalty area.
This will be the third trip to the Open Cup finals for FC Dallas (11-8-3 in Major League Soccer). Dallas will host the New England Revolution of MLS in October.
Leighton O'Brien scored during stoppage time in the second OT for the Sounders, spoiling Dallas goalkeeper Dario Sala's shutout. Sala had allowed 10 goals in his past two games.
Arturo Alvarez started the play that led to FC Dallas' first goal with a cross from the right wing side toward the top of the box. Sounders goalkeeper Chris Eylander came out to cut down the angle. But Ruiz floated the ball over a diving Eylander and watched it drop behind him and into the net.
The Sounders (14-6-6 in USL First Division play) were trying to become that league's first Open Cup finalist since Rochester in 1999.
Alvarez had a wide-open shot at the top of the box in the 61st minute that went wide of the left post for Dallas. Just two minutes later, Sounders defender Taylor Graham headed one off the crossbar in the 63rd minute that would have snapped the scoreless tie.
Dallas starting defender Clarence Goodson went out of the game early in the second half with a concussion.
