Caps lose to Sharks on Saturday, 5-2
Joe Thornton, Patrick Marleau and Brenden Dillon also scored for San Jose. Brent Burns added an empty-netter to seal the win.
Jones made 23 saves, including a poke check on the penalty shot against Jay Beagle with 13 seconds remaining in the second period. Because Burns' slash was a penalty shot and not a minor penalty, the Sharks were able to start the third period on the power play.
That proved crucial when Thornton fed Pavelski near the side of the net. Pavelski then beat Philipp Grubauer with a backhand for his 32nd goal of the season to give the Sharks the lead for good.
T.J. Oshie and Justin Williams scored for the Capitals, who ended a three-game California swing with three points.
