This is Seattle Sounders’ 14th season in Major League Soccer and, so far, they’ve never finished below the play-off line.
But, if the two-time MLS Cup champions fail to win in British Columbia, they would be on the brink of elimination.
Brian Schmetzer’s team endured a torrid August, losing four of five matches and only drawing the other.
But, September brought a new start and new opportunity for the Rave Green, first battling back to beat Houston Dynamo 2-1 at home.
A week later, the Sounders put in their best performance since the CONCACAF Champions League Final, hammering Austin 3-0.
Raúl Ruidíaz scoring twice in a vintage performance, both from the Peruvian striker and his team in general.
So, with four games to go, Seattle are two places and four points below the Western Conference play-off line.
Thus, the margin for error is small if they’re to gatecrash the top seven.
Vancouver Whitecaps meanwhile are just two points below their Pacific Northwest rivals but, having played a game more, their post-season hopes are all but over.
The Caps actually lost three on the bounce, before Wednesday night’s 3-0 drubbing of LA Galaxy.
Ryan Gauld, Pedro Vite and Tosaint Ricketts all scoring as the Blue-and-White enjoyed their joint-biggest victory over LA.
Vanni Sartini’s team have now only lost three of their last 15 home games, picking up the Voyageurs Cup in front of their own supporters in July.
So, this Cascadia Cup clash certainly won’t be easy for Seattle, but will they leave with the victory they so desperately need?
