Bryce Duke scored his first goal of the season and first in his brief career with CF Montreal to help the visitors to a 2-0 victory over Sporting Kansas City on Saturday night.
Duke's goal, in his third game since arriving from Miami in an early-season trade, was Montreal's first on the road this season.
Mathieu Choiniere scored the second as Montreal (3-6-0, 9 points) won their second in a row overall after losing their first five away games under first-year coach Hernan Losada.
Jonathan Sirois made six saves to keep his second clean sheet.
Kansas City (0-7-3, 3 points) remained the last winless team in MLS this season, losing their fourth in a row overall and third straight at home.
They were shut out for a sixth time during a season in which they've scored only three goals so far, by far the MLS low.
Yet they were oddsmakers' substantial favorites coming into the game against a Montreal side that had struggled in all of their travels so far.
But the visitors rarely showed signs of those earlier troubles and opened the scoring in the 35th minute on a wonderful left-to-right move.
Ariel Lassiter, Aaron Herrera and Sean Rea all combined before Choiniere played the throughball to spring Duke in alone on goal.
Duke hammered in a low finish. And although replays suggested he was potentially offside when Choiniere hit the pass, referee Remy Touchan was not called over to review the play on video.
On Choiniere's goal in first-half stoppage time, Herrera played a give-and-go with Rea down the right to cut into the box, then from the byline dragged a cross back toward the penalty area.
Kansas City failed to clear the low roller, and Choiniere ran onto it to pound another first-time finish past goalie Tim Melia.
Daniel Salloi looked closest to pulling a goal back for Kansas City, forcing exceptional saves out of Sirois in the 58th and 69th minutes. Johnny Russell also had a goal in second-half stoppage time disallowed for offside.
