Robbie Keane's LA Galaxy are 90 minutes away from a third MLS Cup final in four years after beating Seattle Sounders 1-0 in their Western Conference Championship final first leg last night.

Brazilian Marcelo Sarvas' deflected shot in the 52nd minute gave Los Galácticos a crucial advantage heading into the decisive leg in Seattle on Sunday.

If Galaxy progress to the MLS Cup final, they will meet the winners of the Eastern Conference Championship.

New England Revolution have the edge in that tie after beating New York Red Bulls 2-1 yesterday.

USA international Jermaine Jones secured New England's first away win over the Red Bulls in seven years with an 85th-minute strike.
