Sebastien Le Toux's first-half goal was enough for Philadelphia Union to pick up all three points against New England Revolution at PPL Park in the MLS.
Union dominated the chances in the first half and came close early on through a Jack McInerney's effort that ended up narrowly wide of the target.
Shortly after, Vincent Nogueria was picked out by Maurice Edu before getting in a strike, which again failed to trouble the Revs goal.
The hosts stepped it up a gear and it paid off when Le Toux made the breakthrough with 31 minutes played, tapping the ball home to give his side a valuable lead.
New England looked to find a way back into the contest, but it was Union who came closest to adding to the scoring when Le Toux's right-footed strike ended up going narrowly wide of the target.
