CHICAGO — Martin Jones made 33 saves for his fifth shutout and Patrick Marleau scored a power-play goal in the second period to lead the San Jose Sharks past the Chicago Blackhawks 2-0 on Tuesday night.
Joe Thornton added a long empty-netter with 1:42 left.
Marleau's goal, on the Sharks' only man advantage, ended his six-game drought and was just his second in his last 17. But it was all the offense San Jose needed to improve to 18-8-2 on the road, best in the Western Conference.
The Sharks, who ended Chicago's three-game winning streak, are 10-2-2 in their last 14.
Jones rebounded to earn his 12th career shutout after allowing five goals on 29 shots in a 6-2 loss at Nashville on Saturday. He is 9-2-1 in his last 12 starts and 16-5-2 on the road.
Chicago goalie Corey Crawford made 25 saves as the defending Stanley Cup champions were blanked for the sixth time this season.
The Blackhawks came out flat off a 5-1 win at Dallas on Saturday night that strengthened their hold on first place in the Central Division.
Chicago's Artemi Panarin, who leads NHL rookies with 52 points, was ill and missed his first game this season. He was replaced by slumping Teuvo Teravainen at left wing on Chicago's top line with right wing and NHL leading scorer Patrick Kane and center Artem Anisimov.
Teravainen entered with no goals in his last 14 games and only one in his last 23.
An apparent goal by Chicago's Brandon Mashinter with 2:37 left in the first period was disallowed following San Jose coach Peter DeBoer's successful video challenge for goalie interference.
Mashinter deflected in a bouncing puck off his right shin guard with no kicking motion, but Chicago's Dennis Rasmussen was in the crease and made contact with Jones.
Marleau opened the scoring with a power-play a goal at 9:09 of the second. His shot from the right point deflected off Chicago's Jonathan Toews and ticked in off the right post with traffic in front of Crawford.
The Sharks had the better chances in the second, but Jones made a point-blank save on Marian Hossa with 1:09 left to preserve San Jose's 1-0 lead.
The Sharks and Jones kept the Blackhawks at bay in the final 2 minutes after Crawford was pulled for an extra attacker.
NOTES: The Blackhawks played their first game at the United Center since Jan. 24 and started a run of four home games in seven nights. . The Sharks return home, where they are 10-12-2, for two games before heading out on a five-game trip. . Marleau appeared in his 512th straight game and is third on the NHL's active ironman list.
