MONTREAL -- Marco Di Vaio scored two goals to lead the Montreal Impact to a 5-0 win over the Houston Dynamo on Saturday night.
Di Vaio and Felipe Martins scored minutes apart in the first half to put Montreal up by two. Jeb Brovsky made it 3-0 in the 58th minute and Di Vaio finished off a two-man break on a pass from Patrice Bernier for his fourth goal in two games.
Andrea Pisano added his first Major League Soccer goal and the Impact won their second in a row, and their third straight at Saputo Stadium.
Troy Perkins made a diving save on a header two minutes into the second half.
Montreal improved to 12-7-5 for 41 points in 24 games.
Houston (10-8-6) lost for just the second time in its past seven MLS games (4-2-1).
Montreal's Justin Mapp slammed a drive off the crossbar from inside the top of the 18-yard box 14 minutes into the match.
Di Vaio opened the scoring with his 14th goal in the 35th minute. The 37-year-old Italian striker took a pass from Mapp and shifted from his right foot to put a left-footed shot into the top left corner.
Felipe made it 2-0 in the 37th minute when he paused to curl a shot around Houston defender Kofi Sarkodie and inside the right post.
Bernier's unselfish play made it a four-goal lead as he drove in with Di Vaio and passed to his left for Di Vaio to put home his 15th goal.
Andrea Pisanu scored Montreal's fifth goal in stoppage time.
Impact assistant coach Mauro Biello guided the team in place of head coach Marco Schallibaum, who served the first game of his two-game league suspension.
Schallibaum, who has been suspended four times this season, received an automatic one-game suspension for his ejection from last Saturday's 2-1 win over D.C. United.
The Swiss coach was suspended by MLS commissioner Don Garber for one more game and fined $5,000 Friday "for his repeated misbehavior."
