SAN JOSE, Calif. — Patrick Marleau scored the tiebreaking goal early in the third period off a nifty, no-look pass from Joe Thornton and the San Jose Sharks extended their home hex over the Washington Capitals with a 5-2 victory Saturday night.

Defensemen Jason Demers, Brent Burns and Marc-Edouard Vlasic also scored for the Sharks, who have not lost at home to the Capitals since October 1993. Torrey Mitchell added an empty-netter to seal San Jose's fourth straight win overall.

Dennis Wideman and Joel Ward scored for the Capitals, who had their four-game winning streak snapped with another loss at the Shark Tank. Since winning their first game ever here, the Capitals have lost 11 times and tied once, getting outscored 46-23.
