MLS: Seattle 1, Chivas USA 1 (tie) CARSON, Calif., May 27 (UPI) -- David Estrada scored shortly after Seattle had surrendered a second-half goal Saturday, salvaging a 1-1 tie for the Sounders against Chivas USA. Estrada finished off a low pass to the front of the net from Alex Caskey in the 61st minute, hitting from 6 yards out for the Sounders (7-3-3). The marker came 4 minutes after the Goats (4-6-3) had grabbed a 1-0 lead when James Riley's right-wing cross was redirected past goalkeeper Bryan Meredith on a Juan Agudelo header. Estrada's goal denied Chivas a second straight win at The Home Depot Center.
