SOUNDERS 6, CHIVAS USA 2
CARSON, Calif. (AP) - Fredy Montero scored a hat trick and Mauro Rosales had three assists to help the Sounders rout Chivas USA.
Brad Evans and Sammy Ochoa also scored for Seattle, which moved into a second-place tie with idle Real Salt Lake in the Western Conference. The Sounders (12-6-7) have won four of their last five games.
Montero scored his first two goals in the 27th and 34th minutes for his first multi-goal regular-season game since May 9. He completed the hat trick and pushed the Sounders' lead back to two goals. Montero reached 11 goals on the season, the fourth time in four seasons he has reached that milestone.
Juan Agudelo scored a penalty kick as Chivas (7-10-6) went into the intermission down 3-1. Miller Bolanos scored in the 64th minute, but Montero's goal 3 minutes later quieted the comeback. Rosales assisted on all three of Montero's goals.
EARTHQUAKES 4, RAPIDS 1
SANTA CLARA, Calif. (AP) - Simon Dawkins and Alan Gordon each scored a pair of goals and the Earthquakes cruised to a victory over the Rapids.
The league-leading Earthquakes (15-6-5) extended their unbeaten streak at Buck Shaw Stadium to 10-0-4 since Aug. 13, 2011. San Jose's only home loss in MLS play this season occurred at AT&T Park, where Houston beat the Earthquakes 1-0 on March 17.
Gordon extended his career-best single-season scoring mark to 11 goals with strikes in the 43rd and 75th minutes. Dawkins put San Jose up in the 11th minute and tallied again in the 68th for his fifth and sixth goals of 2012
TIMBERS 2, WHITECAPS 1
PORTLAND, Ore. (AP) - Franck Songo'o scored the go-ahead goal and the Timbers snapped a nine-match winless streak with a victory over Pacific Northwest rival Vancouver.
Songo'o's goal, his first with the Timbers, came on a free kick in the 55th minute that beat Whitecaps goalkeeper Joe Cannon.
Portland had not won since a 2-1 victory over San Jose on July 3. The Timbers were 0-6-3 going into the sold-out Cascadia Cup match against the Whitecaps.
The Cascadia Cup is the annual head-to-head competition between Major League Soccer's three northwest teams: the Timbers, Whitecaps and the Seattle Sounders. Vancouver has yet to win a Cascadia match since joining MLS last season.
