MLS-best LAFC loses at Vancouver on goal in the 89th minute
Cubas intercepted a clearing attempt, taking the ball off his chest at the top of the penalty area, and fired a right-footer past former Whitecaps goalkeeper Maxime Crepeau and into the bottom-left corner.
Vancouver improved to 7-8-3. MLS-leading LAFC dropped to 11-4-3.
Cristian Arango, Danny Musovski and Kwadwo Opoku each scored for LAFC in a 3-1 victory over Dallas on Wednesday at Banc of California Stadium.
Crepeau made a save in his return to BC Place. Jeers and boos rained down on the 28-year-old Canadian nearly every time he touched the ball.
Crepeau started 32 games for Vancouver between 2019 and 2021 but requested a trade ahead of the 2022 season because of what Whitecaps sporting director Axel Schuster has described as a “very personal situation.”
Vancouver goalkeeper Cody Cropper did not have a save but recorded his fourth shutout of the season.
