The Philadelphia Union Can Still Clinch 1st Place In The Eastern Conference If....
D.C. United defeat Sporting Kansas City by two or more goals. AND Chicago Fire defeat or draw Columbus Crew AND Los Angeles Galaxy defeat or draw Houston Dynamo. EDIT: Furthermore if NONE of these three things happen, Philadelphia Union become a wild card team. If on top of none of these three things happening, Colorado Rapids defeat Vancouver Whitecaps, the Union will travel to Colorado for a wild card game. Disaster. (h/t Joey Samuel in the comments.)
