A Harold Cummings own goal and some poor finishing from San Jose made sure of the result for Minnesota, keeping the Loons perfect with two wins from their opening two fixtures of the season.
Luchi Gonzalez earned his first win as the head coach for FC Dallas, the Texas outfit rolling to a 2-0 victory over an LA Galaxy side playing without star man Zlatan Ibrahimovic.
Reto Ziegler opened the scoring from the penalty spot for the home side just after the break following Diego Polenta high kick on Matt Hedges, but it was a stunner from Bryan Acosta, his first MLS goal, that locked up the win.

Paxton Pomykal's cut-back from the line found Acosta just outside the Galaxy box and he struck a brilliant first-timer to give FCD's new manager a first win.
In Seattle, the Sounders continued their flying start to the season, scoring twice early on to put away the Colorado Rapids 2-0.

Zack Steffen's penalty stop helped set the stage for a 2-0 win for the Columbus Crew over the New England Revolution.
Gyasi Zardes had headed the Crew in front in first half, but Diego Fagundez had a chance to pull New England level on the hour mark from the spot, only to see a sprawling Steffen palm his attempt away. Zardes slid a second home on a counterattack deep into stoppage time to make sure of the result for the visiting Crew.
A CJ Sapong goal five minutes into stoppage time earned a 1-1 draw for the Chicago Fire. Dom Dwyer had opened the scoring early in the second half for Orlando City, sneaking in behind to poke home after an ambitious flick forward from Nani. A Jorge Corrales red card also left the Fire to finish the match down a man, but Sapong was able to rise highest and head home a Przemyslaw Frankowski cross deep into stoppage time to earn the draw.

The Houston Dynamo stayed unbeaten on the young season, following up an opening-weekend draw with a 2-1 win over the Montreal Impact on Saturday.
Saphir Taider put the Impact in front on the half-hour mark, but a rocket of a hit from Memo Rodriguez had the Dynamo back on level terms five minutes later. The home side found a winner late on through Mauro Manotas, who tapped home from just in front following a driven Romell Quioto cross.
Real Salt Lake also stayed unbeaten, winning for the first time in 2019 thanks to an Albert Rusnak penalty that helped the side to a 1-0 result against the Vancouver Whitecaps.
