Lamar Neagle scored for Seattle in the 72nd minute as the Sounders drew with the Vancouver Whitecaps 1-1 in their CONCACAF Champions League game on Wednesday night.
Tim Parker replied for the Whitecaps as both clubs opened Group F play.
Neagle scored off a free-kick that looped over the penalty area to Andy Rose on the right. He sent a ball back into the box to Neagle and he fired a shot high over Paolo Tornaghi.
Parker gave the Whitecaps the lead 11 minutes earlier with a beautiful glancing back-heel flick off Pedro Morales' corner that beat a Troy Perkins to the far post.
The Whitecaps fielded an entirely different starting 11 from their 3-0 road victory over Seattle on Saturday in Major League Soccer, while the Sounders made eight changes.
