The cards were flying as San Jose came out on top against Seattle thanks to a goal from Walter Martinez.
The Sounders were rocked by injuries early, using all their subs to replace Drad Evans, Michael Gspurning, and Djimi Traore in the 32nd minute, at halftime, and in the 53rd minutes, respectively.
San Jose capitalized on the confusion in Seattle's defensive unit with a goal shortly after the re-start. Steven Lenhart picked out Walter Martinez on the far post, who cut inside past DeAndre Yedlin and curled a shot just inside the far post
Seattle's woes were further compounded in stoppage time, when Osvaldo Alonso was sent off following an altercation with San Jose's Dan Gargan.
