The San Jose Sharks continued on a downward spiral Sunday night, losing 3-1 to the Vegas Golden Knights, their third straight loss and ninth in 10 games.
Shea Theodore scored the tiebreaking goal with 11:55 remaining in the third period for the Golden Knights, who won their ninth in 13 games.
Paul Stastny and Jonathan Marchessault also scored, and Malcolm Subban made 37 saves to keep the Golden Knights tied for first place in the Pacific Division with Arizona.
Logan Couture scored for the Sharks, and Aaron Dell made 34 saves.
The Sharks weathered a storm early in the third period, icing the puck four times in a span of 48 seconds, before putting pressure on for the tying goal.
Brent Burns skated around the net on a power move and fed Couture on the other side for a one-timer and his 12th goal of the season.
Dell then made big stops on William Carrier and Brayden McNabb on one sequence to preserve the tie and earn a loud ovation from a fan base that has been waiting for top-notch goalie play all season.
But that didn't last long as Theodore beat Dell with a wrist shot from the circle to make it 2-1 moments later.
Vegas added an insurance goal late in the period after Reilly Smith beat Erik Karlsson on a rush and fed Marchessault in the slot.
The final regular-season meeting between the Pacific Division rivals got off to a tight, defensive start with only a handful of scoring chances in the first two periods.
Nicolas Hague had a shot for Vegas deflect off both posts and out in the first period. Hague, who also hit the crossbar, is still seeking his first career goal.
Dell robbed Mark Stone with a glove save on a power play just moments after Subban stopped Evander Kane on a 2-on-1 at the other end.
Joe Thornton then had two good chances in the second for his first goal of the season but was stopped twice by Subban.
The Knights finally broke through late in the second when Alex Tuch found Stastny in the slot for his ninth of the season.
Vegas nearly added to that but Dell covered up a puck on the goal line as San Jose defenseman Brenden Dillon got into a scuffle with Ryan Reaves.
