Thursday's Cascadia clash ended in elation for the Portland Timbers, who slipped past their Pacific Northwest rivals on penalty kicks to advance to the next round of the MLS playoffs.
A stoppage time goal from the Sounders forced extra time, but the Timbers came through in penalty kicks with a 4-2 shootout victory. The initial 90 minutes ended at 2-1 in favor of the Sounders following a 2-1 opening leg at Providence Park, and the sides traded goals in extra time, making it 3-2 on the night and 4-4 on aggregate, to prompt a shootout.
Once there, both teams made their first spot kicks before the Sounders missed two in a row to give the Timbers the advantage.
