MONTREAL -- Dom Dwyer took advantage of a defensive lapse to score his second goal of the game in the 89th minute, lifting Sporting Kansas City to a 2-1 victory over the Montreal Impact on Saturday night.

Montreal defender Heath Pearce and goalkeeper Troy Perkins got their signals crossed, and neither cleared a harmless ball away from the 18-yard box. The hesitation was enough for Dwyer to pounce on the loose ball and get his 14th goal of the season to give Sporting (8-5-5) its third victory in four games.

Dwyer, who has six goals against Montreal this season, opened the scoring in the fourth minute.

Marco Di Vaio tied it for the Impact (3-9-5) with a header in the 28th for his third goal of the season.
