Michael Farfan scored the tiebreaking goal in the fifth minute of injury time on a beautiful pass from Lionard Pajoy, and the Philadelphia Union stunned the Los Angeles Galaxy in a 2-1 victory Wednesday night.

Chad Barrett tied it with his first goal of the season in the 73rd minute for the Galaxy (6-10-2), who played without David Beckham due to suspension.

Jack McInerney scored in first-half injury time for the Union (4-9-2), who won for just the second time in nine MLS matches.

The defending champion Galaxy had far more good scoring chances, but Farfan set up McInerney's first-half goal before scoring the winner deep into injury time. Pajoy made a slick back-heel pass on the run to Farfan, who scored through the Galaxy's defense to silence a large Los Angeles holiday crowd.
