It all comes down to this. After 38 matches, there are only two teams left in the race for MLS Cup. The Portland Timbers came into the postseason as the fifth seed but have surged into the knockout rounds, beating out top-seeded Sporting Kansas City in a 3-2 road win last week. But as the side with more regular-season points, Atlanta United earn the right to host the event for the first time after series wins over both clubs from New York. The Five Stripes could add their first MLS Cup to their trophy cabinet this weekend against the best of the west.
