Three goals in the final 20 minutes lifted the Los Angeles Galaxy to a 4-1 Major League Soccer victory over the Philadelphia Union at PPL Park on Wednesday evening. Zac MacMath\'s early own goal - the ball finding its way into the net via the Union goalkeeper\'s face and the crossbar - edged the Galaxy ahead only for Amobi Okugo\'s strike midway through the first half to get the hosts back on level terms. But the visitors ran riot after the interval. Robbie Keane, returning to the Galaxy line-up after three games out with an ankle injury, coolly slotted the go-ahead goal in the 71st minute from Landon Donovan\'s assist, with further goals from substitute Hector Jimenez and Donovan - on his 200th appearance for the club - sealing a convincing away win. The result moved Los Angeles up one place to third in the Western Conference standings and left Philadelphia fifth in the Eastern Conference. Source: fifa.com
