Update: These teams have met in two of the last three Western Conference finals, with the Galaxy winning both times. But neither is playing like a title contender at the moment. The Galaxy has lost its last two, is winless in its last four and hasn't scored in 267 minutes. But the Galaxy has also gone 21 games since its last loss at the StubHub Center. The Sounders, meanwhile, had just two shots on goal in their last two games — yet they managed to come away with a win and a draw. This game is likely to be decided in the midfield, where Seattle will be without Gonzalo Pineda, who earned a straight red card last weekend against Houston. The Sounders are expected to have enforcer Osvaldo Alonso though while the Galaxy will continue to search for chemistry in the midfield after the winter trade that sent Marcelo Sarvas to Colorado. The officials may also be worth watching in this one: Last summer, Mark Geiger became the first American to referee a knockout game in a World Cup.
