Johnny Russell netted Sporting KC's lone goal in the 43rd minute, but the Whitecaps held the visitors off the scoresheet in the second half to claim the three-point result.
Vancouver opened the scoring 23 minutes in courtesy of Gauld's third goal of the season. The Scottish attacking midfielder pounced on a ball that was expertly headed back across goal by Brian White, lashing a shot on target that deflected off SKC defender Ilie Sanchez and into the net.
Teibert then doubled Vancouver's advantage in the 36th minute, collecting a ball atop the area and smashing a precise shot that evaded a diving Tim Melia before glancing off the post and in, giving the hosts a 2-0 cushion.
The visitors struck back shortly before halftime through Russell's classy finish. The Scottish forward teed up a distance look of his own from the right side that he curled inside the far post, giving SKC a crucial goal heading into the break.
But Teibert's strike stood as the game-winner, as Sporting pressed for an equalizer that never materialized in the second half, allowing Vancouver to preserve the 2-1 final score.
- THE BIG PICTURE: At the end of some entertaining MLS After Dark action, it's a crucial three points for the Whitecaps, who now find themselves just one point shy of Minnesota United FC for the seventh and final playoff bid in the West and have everything to play for down the stretch. On the flip side, Sporting Kansas City missed a chance to pull closer to the top-seeded Seattle Sounders, who had given an opening for Peter Vermes' group to cover some ground after a road defeat of their own at Houston Dynamo FC.
- MOMENT OF THE MATCH: Russell Teibert doesn't score many, but this finish is all class – and it ultimately delivered his team a massive result.
- MAN OF THE MATCH: Ryan Gauld continues to impress as a Designated Player, scoring Vancouver's first goal and showcasing some of the electric passing ability that makes him such a well-rounded threat.
