CARSON, California (AP) — Robbie Keane scored two goals and set up another as the Los Angeles Galaxy beat the Seattle Sounders 3-0 on Sunday to take a commanding lead in the first leg of the Major League Soccer Western Conference finals.
Mike Magee added the other goal for defending champion Los Angeles, which will head to Seattle next Sunday in prime position to earn its third MLS Cup appearance in four years.
If Los Angeles survives and the Houston Dynamo wraps up the Eastern Conference finals after beating D.C. United 3-1 in the first leg earlier Sunday, the MLS Cup would be a rematch of last season's game, which David Beckham and the Galaxy won at Home Depot Center.
Andre Hainault, Will Bruin and Kofi Sarkodie each scored second-half goals at Houston to give the Dynamo the win over United.
Nick DeLeon scored for United in the 27th minute.
The win gives Houston a two-goal aggregate lead heading into next Sunday's decisive match at RFK Stadium in Washington. United will have to win that match by three goals to advance.
The Dynamo extended their home unbeaten streak to 30 games, dating to June 18, 2011. Houston is four wins or draws away from matching Real Salt Lake's league-record 34-game home unbeaten run.
