Torres entered the match in the 67th minute and then found himself in perfect position less than a minute later. New York's Tim Ream passed the ball directly to Philadelphia forward Danny Mwanga, who then took a couple of dribbles and left Torres an easy ball to send into the net.
Union goalkeeper Faryd Mondragon earned his third victory and third shutout this season. Philadelphia already has more shutouts than in all of last season.
The Union (3-1-0) moved into first place in the Eastern Conference with nine points.
