The Sounders didn't generate a truly dangerous scoring chance during the entire first half and didn't get their first shot on goal until they were already trailing by three goals. Even with the caveat that several of their top defenders were missing -- most notably Chad Marshall, who was suffering from back spasms after a Saturday car accident -- it was a rather depressing performance.
Almost from the opening whistle, the Galaxy had the Sounders on their heels and stormed ahead in the 8th minute on a Gyasi Zardes goal. After Jalil Anibaba's giveaway in the offensive half got the counter-attack going, Marcelo Sarvas put Landon Donovan in behind Anibaba and dropped it back to Zardes, who beat Stefan Frei on a relatively simple finish.
Just 10 minutes later, the Sounders completely lost track of Donovan after Sarvas was allowed to take a wide open shot from outside the penalty area. Donovan was all alone to put away the rebound.
The Galaxy effectively put the match away in the 36th minute when Stefan Ishizaki finished another wide open chance from a Sarvas pass on a counter-attack.
Although the Sounders were able to generate some chances in the second half, they never looked capable of climbing back into the match.
Despite the loss, the Sounders remain tied for the Supporters' Shield lead with Sporting Kansas City and have two games in hand.
