Hassoun Camara got his first MLS goal and Patrice Bernier scored on a penalty kick in the second half, lifting the Montreal Impact to a 4-2 victory over the Houston Dynamo on Saturday night.
Sanna Nyassi and Davy Arnaud also scored for Montreal (5-8-3).
Will Bruin got his ninth goal and Brad Davis also scored for Houston (5-5-5). Former Impact forward Brian Ching had an assist.
Houston's Adam Moffat received a red card after bringing Montreal's Felipe Martins down hard in the 73rd minute.
The Impact took the lead when Arnaud flicked Martins' corner kick to Camara, who scored with a header at the far post in the 60th minute. After Felipe went down in the penalty area following a light shove from Geoff Cameron eight minutes later, Bernier converted the penalty kick.
