Minus Jack Jewsbury, the Timbers were able to stun the Galaxy and pick up their first home win in seven attempts.
Playing shorthanded with captain Jack Jewsbury on the sideline, the Portland Timbers still managed to shock the Galaxy as they rolled to a 3-0 victory Wednesday at JELD-WEN Field.
Mike Chabala and Jorge Perlaza scored in the first half and Eric Brunner had the dagger midway through the second to lead the eighth-seeded Timbers, who hadn't won at home since May 21.
The Timbers had 15 shots on LA goalkeeper Josh Saunders, while the Galaxy only managed seven against Portland keeper Troy Perkins.
Chabala, who was acquired by Portland in a trade with Houston two weeks ago, had his first goal of the season when he got in the box and put one in the back of the net in the 26th minute.
Perlaza's goal came in the 33rd minute and Brunner's in the 68th.
The Galaxy, who were looking for a franchise-record streak of unbeaten games, failed to record a shot in the first half and put on most its pressure in the closing minutes with the game already out of reach.
Jewsbury, an All-Star midfielder, was out with a strained hamstring.
