Seattle Sounders extend shutout streaks into the MLS Cup final

The Seattle Sounders have reached their second-straight MLS Cup final and they did so again because of their stifling defense.

The Sounders will enter MLS Cup against Toronto FC having not conceded a goal in the Audi MLS Cup Playoffs in 647 minutes, dating back to last year's championship run. They have done so largely on the back of the center back partnership of Roman Torres and Chad Marshall but managed to hold the Houston Dynamo scoreless on Thursday night with Gustav Svensson filling in for Torres.

Their defensive run has been nearly as impressive this season, as they have not conceded in their last 542 minutes. The last goal they conceded came on Oct. 1 against the Philadelphia Union.

Of course they held Toronto scoreless in last year's MLS Cup final, and will look to do so again an even better attack that now includes Victor Vazquez in addition to Jozy Altidore and Sebastian Giovinco.
