| In the Western Conference, Nelson Valdez scored with a diving 
				header in the 88th minute to lead the Seattle Sounders to a 1-0 
				win over Sporting Kansas City.
 The Sounders will play top-seeded FC Dallas in the semi-finals 
				while Impact will face New York Red Bulls.
 
 In Washington D.C., Montreal's Laurent Ciman scored his first 
				goal since the 2015 regular season with less five minutes on the 
				clock before Mancosu scored either side of half-time.
 
 Ignacio Piatti made it 4-0 with seven minutes left before Lamar 
				Neagle and Taylor Kemp scored in the dying moments for 
				fourth-seeded D.C.
 
 In the other playoff game, Valdez was mobbed by his team mates 
				after scoring the late winner at CenturyLink Field.
 
 Seattle were ninth in the 10-team Western Conference after a 
				loss to Kansas City on July 24 and two days later long-time 
				coach Sigi Schmid was fired.
 
 Under interim coach Brian Schmetzer, Seattle climbed the table 
				to fourth, the turnaround all the more surprising given Clint 
				Dempsey has been out since late August due to an irregular 
				heartbeat and will not return to action in the postseason.
