Portland Timbers have cut the gap on Seattle Sounders to one point in the MLS Western Conference with a 1-0 victory over Los Angeles Galaxy at Jeld-Wen Field.

The only goal of the game came seven minutes after the break when Will Johnson's corner to the near post was flicked home by Maximiliano Urruti.

Robbie Keane thought that that he had snatched a point for the Galaxy in the last minute, but the linesman ruled his header from Landon Donovan's free kick offside.

Defeat for Bruce Arena's men leaves them just four points ahead of the Vancouver Whitecaps in the race for a playoff spot.
