Real Salt Lake maintained their unbeaten start to the MLS season but two goals in the last five minutes helped the Vancouver Whitecaps to a 2-2 draw. Goals from Joao Plata and Alvaro Saborio in the opening ten minutes appeared to put the home side on course for their fourth win of the campaign.
But they were instead forced to settle for their fifth draw this term as Nicolas Mezquida gave the Whitecaps hope before fellow substitute Sebastian Fernandez levelled matters with his last-gasp effort. The two late strikes prevented Real Salt Lake from joining the Seattle Sounders and Dallas FC on 16 points.
Clint Dempsey bagged a brace in a virtuoso display as the Sounders eased to a 4-1 win over the Colorado Rapids. The former Fulham striker grabbed a quickfire brace in the 47th and 52nd minutes after Lamar Neagle had opened the scoring on the stroke of half-time and although Dillon Serna pulled a goal back for the Rapids just after the hour mark, Obafemi Martins restored the three-goal cushion after 75 minutes.
That took Seattle to the top of the standings in the Western Conference after nine-man Dallas were beaten 4-1 at DC United. Mauro Diaz put the visitors in front after 13 minutes but Zach Lloyd's 39th-minute dismissal was to prove their downfall as Fabian Espindola equalised on the stroke of half-time. Three goals in nine minutes just after the hour mark from Bobby Boswell, Sean Franklin and Espindola settled the match in DC United's favour, with Dallas' misery compounded by Garbini Michel's red card in the 89th minute.
Lee Nguyen, from the penalty spot, and Teal Bunbury both scored in injury time to lift the New England Revolution to a 2-0 win over Sporting Kansas City, who were left to rue Aurelien Collin's sending off 15 minutes from time. That result meant Columbus Crew went to the top of the Eastern Conference following a 1-1 draw with the New York Red Bulls. Jairo Arrieta gave the hosts a 41st-minute lead but Bradley Wright-Phillips gave the Red Bulls a share of the spoils just after the hour.
Second-half substitute Yanick Djalo's 66th-minute strike sealed a 1-0 win for the San Jose Earthquakes over Chivas USA, who had goalkeeper Dan Kennedy sent off after 77 minutes, while the Montreal Impact beat Philadelphia Union by the same scoreline following Felipe Martins' 15th-minute effort.
