Bradley Wright-Phillips gave Columbus Crew a 1-0 lead late in the second half, but back-to-back goals from Xavier Arreaga and Will Bruin helped Seattle snatch a 2-1 road victory on Saturday night at Lower.com Field.
Wright-Phillps had the Crew in the driver's seat after opening his Crew account in the 77th minute, but Arreaga and Bruin scored in a wild two-minute span right before second-half stoppage time, allowing the Sounders to take all three points.

Seattle had their chances in the first half, perhaps most notably off a header from Yeimar Gomez Andrade set up by a Joao Paulo free kick that forced Columbus goalkeeper Eloy Room into a reaction save.
Raul Ruidiaz and Fredy Montero each also had looks for Seattle in opening half-hour, but Ruidiaz saw his 13th-minute laser shot go just high, while Montero saw a look from distance saved again by a sprawling room.
Columbus had perhaps their best chance of the first half in the 34th minute off a free kick from Lucas Zelarayan that was met with a whipped header from Jonathan Mensah that the center back put high of the target.
Wright-Phillips would find Columbus' breakthrough in the 77th minute after entering the match as a second-half substitute. The longtime New York Red Bulls star slotted home a point-blank finish after a Zelarayan corner kick was headed down in front of goal, giving the hosts the tally that would stand as the game-winning strike.
That looked like it would be enough to give the hosts the victory, but the Sounders would strike back with a pair of late tallies, first from an unlikely source in Arreaga. The center back got his foot to a cross from Jimmy Medranda for a close-range finish to tie it at 1-1.
Bruin then found a huge game-winner slotting him his first goal of the season with a clinical finish from inside the area just one minute later for the decisive tally.
