SEATTLE -- Clint Dempsey scored twice in a five-minute span early in the second half and set up Lamar Neagle's first-half goal to help the Seattle Sounders beat the Colorado Rapids 4-1 on Saturday.

Dempsey leads MLS with eight goals. He has at least a goal or an assist in each of Seattle's last six games. It is the second time in his career that Dempsey has had a six-game scoring streak in MLS, having done it previously in 2005 while with the New England Revolution.

Obafemi Martins added a 75th-minute goal for Seattle. The Sounders have won three straight to improve to 5-2-1. Dillon Serna scored in the 62nd minute for the Rapids (3-2-2).

IMPACT 1, UNION 0

MONTREAL -- Felipe Martins scored in the first half and Montreal held on to beat Philadelphia for its first MLS victory of the season.

It was the Impact's (1-4-3) first win since a 2-1 decision over Philadelphia on Oct. 19 last season.

Philadelphia (1-3-5) is winless in its last seven games.

Felipe got his second goal of the season in the 15th minute when Patrice Bernier stole the ball from Sheanon Williams and took a long shot that Zac MacMath blocked, only to fee the Brazilian bang in the rebound.
