Sporting Kansas City closed the gap to Western Conference leaders Dallas, while the Portland Timbers claimed an important MLS win on Saturday.
A Felipe Gutierrez goal was enough to see Sporting to a 1-0 victory over Orlando City in Kansas.
Gutierrez produced a fine low finish from 20 yards in the 53rd minute for the only goal of the game.
The result moved Peter Vermes' Sporting up into second and to within a point of conference leaders Dallas.
The Timbers are on track to feature in the play-offs after a 2-0 win over the Colorado Rapids.
Jeremy Ebobisse and Diego Valeri scored either side of half-time to move the Timbers four points clear of the seventh-placed Vancouver Whitecaps in the Western Conference.
Elsewhere, David Villa's late goal secured a 1-1 draw for New York City at home to DC United.
