The Sounders lost their fourth straight, ending their Supporters' Shield hopes and putting their playoff positioning in doubt.
Seattle lost its fourth straight match Saturday, falling 2-0 at FC Dallas. With one game left, the Sounders find themselves in third place in the Western Conference, eliminated from the Supporters' Shield race and just one point ahead of the fourth-place LA Galaxy. If Seattle finishes fourth or fifth, it must win a one-off match to make the conference semifinals.
Dallas, which entered the game on an 0-4-1 skid and had already been eliminated from playoff contention, used second-half goals from Matt Hedges and Michel to give outgoing coach Schellas Hyndman a win in his home finale.
After Brad Evans' volley and Lamar Neagle's bicycle kick missed the mark for Seattle early in the second half, it was Dallas that went ahead. Minutes after coming on, Michel whipped in a free kick that Hedges rose to nod home in the 65th minute.
Dallas grabbed the insurance goal in the 87th minute as Seattle goalkeeper Marcus Hahnemann was thrown out of position by David Ferreira's deflected shot, leaving an open goal for Michel to slot into.
