The LA Galaxy, with their win on Saturday against Real Salt Lake, made it so that the Seattle Sounders were the only team mathematically capable of catching them in the standings. However, the Sounders were going to have to win out, and even then the Galaxy could eliminate them with enough another victory. Well Seattle went ahead and made things simpler tonight, losing to the Philadelphia Union 2-0 at their downtown Seattle stadium.
With Seattle's loss, LA clinches the Supporter's Shield for the second straight year. With an 18-4-10 record and 64 points, the Galaxy have tied MLS' record for points since draws were allowed, and with two games left are within shooting distance of the MLF all time record for points.
This is the Galaxy's fourth Shield win, which ties them with DC United for the most wins at four a piece. They also join DC United and the Columbus Crew as the only MLS clubs to finish top of the table back to back.
Five teams in MLS history have won the double, with the last one being the Columbus Crew in 2008. The Galaxy won the double in 2002. The Galaxy have clinched home field advantage throughout the playoffs, and have earned an automatic birth in the 2012-13 CONCACAF Champions League.
