New England Revolution have come from a goal behind to defeat Toronto 2-1 at BMO Field.
The home side were ahead after just six minutes when Jackson Goncalves's effort was deflected past Bobby Shuttleworth at the near post.
Revolution found an equaliser through Patrick Mullins, who was picked out by Daigo Kobayashi before drilling a shot past Julio Cesar from 20-yards out.
It looked as though the game was going to end all-square, until Mullins saw his effort come back off a hand inside the box, with the referee awarding a penalty.
Lee Nguyen stepped up to take the spot kick and made no mistake, giving the visitors an 83rd-minute lead which they managed to hold on to.
