David Villa continued his goal scoring exploits for New York City while Clint Dempsey scored twice as the Seattle Sounders boosted their Western Conference play-off hopes with a 3-1 victory over the Portland Timbers at CenturyLink Field.
The 33-year-old former Fulham and Tottenham forward opened the scoring from the penalty spot in the 62nd minute after Vytautas Andriuskevicius had fouled Cristian Roldan, and doubled his side's advantage by fizzing a low shot past Jake Gleeson 10 minutes from time.
Roldan sealed matters three minutes later when he headed home from Brad Evans' nod-down, with Fanendo Adi's strike in the third minute of time added on scant consolation for the visitors.
DC United battled from two goals down to draw 2-2 against the New York Red Bulls in a match which was subject to a 75-minute weather delay after lightning struck seven minutes into the contest.
When the action resumed, Red Bulls' all-time leading scorer Bradley Wright-Phillips put the visitors ahead seven minutes before half-time and Felipe made it 2-0 in the 64th minute.
But Marcelo converted a 70th-minute penalty to give the hosts hope and Patrick Mullins grabbed his side a point by heading home the equaliser three minutes later.
On Saturday, David Villa's 16th goal of the season helped New York City FC edge the Los Angeles Galaxy 1-0 to stay top of the Eastern Conference.
