Montreal Impact's Alejandro Silva scores twice in beating Union

Alejandro Silva scored two goals, Saphir Taider and Quincy Amarikwa each scored one goal and the Montreal Impact defeated the host Philadelphia Union 4-1 Saturday night at Talen Energy Stadium.

Ignacio Piatti added a pair of assists for the Impact.

The Impact (12-14-3, 39 points) climbed within one point of the Union (12-12-4, 40 points) for fifth place in the Eastern Conference.

Montreal earned just its third road win of the season and also registered its first win when the opposition scores first. It had been 0-12-1 heading into this game.

Auston Trusty scored for the Union, who had their five-game unbeaten streak snapped. The Union had been 4-0-1 over their last five games.

In the 11th minute, the Union played a corner kick short, and Borek Dockal sent a cross in the box, and Trusty headed it into the goal for his first career goal. Dockal registered his league-leading 15th assist. Dockal's 15th assist also tied a Union record for assists in a season originally set by Cristian Maidana in 2015.

Silva tied the game at 1 in the 28th minute when the Impact countered quickly. Piatti dribbled down the middle and sent a crisp pass to Silva, who easily sent the ball into the back of the net for his third goal.

The Impact took a 2-1 advantage in the 39th minute when the ball ricocheted off Union goalkeeper Andre Blake and Taider capitalized on the rebound.

Philadelphia's Fafa Picault hit a strike from about 20 yards out but it was stopped by Impact goalkeeper Evan Bush in the 53rd minute.

Amarikwa pushed the Montreal lead to 3-1 in the 63rd minute when he slid into the box and deflected a shot past Blake. Daniel Lovitz was credited with the assist for the centering pass to Amarikwa.

Silva notched his second goal of the game -- and fourth of the season -- in the 76th minute. Piatti earned his second assist of the game and has 11 this season.
