Philadelphia Union lost Kai Wagner to a minor quad injury prior to kickoff then gave up four goals to Real Salt Lake as they fell on the road at Rio Tinto Stadium Saturday night. RSL pressed the Union early and often, and the visitors never got into a rhythm with the ball. Passes went astray, players looked uncoordinated, but for a while it appeared Philly could find its footing before Real Salt Lake broke the deadlock. In the 15th minute, a good move up the Union left was broken up when Auston Trusty slid into a passing lane to the center to knock the ball out of play.
