Whitecaps 4, Sounders FC 1 • At Seattle, Kekuta Manneh recorded the first hat trick of his MLS career and Vancouver kept its playoff hopes alive with a win over Seattle.
Manneh took advantage of breakdowns in Seattle's back line for goals in the 12th, 42nd and 54th minutes. Vancouver (12-11-9) denied Seattle a chance to clinch the Cascadia Cup the regional rivalry between the Sounders, Whitecaps and Portland Timbers.
Seattle (15-10-6) must win Sunday at Portland to claim regional bragging rights, otherwise it'll go to Vancouver.
The loss was Seattle's first at home since dropping the season opener to Montreal back in March and could be a significant blow to the Sounders' chances of winning the Supporters' Shield for most regular-season points in the league.
Manneh's hat trick was the first for Vancouver since the franchise joined MLS in 2011.
Sporting Kansas City 0, Dynamo 0 • At Houston, Jimmy Nielsen had five saves, while Tally Hall had one stop and Sporting Kansas City and Houston played to a tie.
The draw extends Houston's unbeaten streak to five games, but the Dynamo (13-10-9, 48 points) were unable to close the gap on Kansas City (15-10-7, 52 points), which remained four points ahead of the Dynamo in second place in the Eastern Conference.
