The four cups ties Seattle with the Chicago Fire for the most by an MLS team. However, the Sounders have clustered their four wins in six seasons of existence.
This was the Sounders' path to the 2014 Cup: beating amateur PSA Elite, 5-0; San Jose on PKs, Portland, 3-1 in extra time; Chicago, 6-0; and finally Philly 3-1 in extra time.
Seattle fell behind 1-0, and then stormed to the victory with goals from Chad Barrett, Clint Dempsey and Obafemi Martins.
Sounders also awarded $250,000, have name engraved on the Dewar Challenge Trophy, and qualifies for 2015-16 CONCACAF Champions League.

Lineups: For Seattle: Frei; Yedlin, Marshall, Scott, Gonzalez; Evans, Alonso, Rose, Neagle; Barrett, Dempsey. Reserves: Hahnemann, ANibaba, Azira, Cooper, Martins, Pappa, Pineda. The interesting one there is the Barrett-Dempsey pairing up top, with Martins in reserve.
