The Senators struck quickly, recording a power-play goal less than four minutes into the contest. Mike Hoffman tossed the puck toward the net and it bounced off Burns’ skate. Burns lost sight of it and Stone picked it up, firing past everybody into the net.
Hoffman has a point in six straight games and in eight of nine since missing a pair of contests with an injury.
Karlsson made it 2-0 with a goal about four minutes later. Sharks defender Brendan Dillon tried clearing it from in front of the net, but Karlsson was right there to fire it to the high glove side.
Couture got the Sharks on the board with a power-play goal midway through the second period. The Senators cleared the puck two straight possessions before Joe Pavelski rushed to the net and then slipped the puck to an open Couture, who has six goals in his past eight games, about 10 feet away for the score.
Burns tied the score 6:30 into the third period, methodically working the puck to set up a shot that squeezed past Condon to the glove side.
