VANCOUVER, British Columbia — Kari Lehtonen made 42 saves and the Dallas Stars defeated the Vancouver Canucks 2-1 on Sunday.Valeri Nichushkin and Erik Cole scored for Dallas (11-7-2), which was coming off a 7-3 victory over the Calgary Flames on Thursday and extended its road winning streak to six games. Henrik Sedin scored for Vancouver (11-8-3), which got 21 saves from Roberto Luongo as the Canucks dropped their fourth in a row. After Lehtonen kept Vancouver off the scoreboard in a second period that had Vancouver hold a 20-6 edge in shots, Cole made it 2-0 early in the third. Henrik Sedin made a poor decision to step up at the Dallas blue line while covering for a pinching Kevin Bieksa, resulting in a 2-on-1 break the other way that saw Cody Eakin pass to Cole for his second of the season at 1:42 of the third. Henrik Sedin had a goal in the second period waved off, but got Vancouver on the scoreboard at 3:06 of the third when he chipped a shot over Lehtonen with the Canucks on the power play for his fourth of the season. Vancouver made a late push, but Lehtonen wasn’t really troubled much the rest of the way in recording his 10th win of the season as the Canucks mustered 10 shots in the final period. Down 1-0 after the first, Vancouver looked to have tied it at 6:42 of the second when Henrik Sedin beat Lehtonen upstairs from a sharp angle.The celebrations were short-lived, however, as the goal was waved off for what the officials deemed “incidental interference” by Daniel Sedin on Lehtonen at the top of the crease. Television replays appeared to show no contact between the two players, which left both the crowd at Rogers Arena and Canucks coach John Tortorella incensed. The Canucks’ 28th-ranked power play had another chance on the same man advantage, but Lehtonen made a great stop on Bieksa. The Stars’ top line continued its recent hot streak when Nichushkin opened the scoring at 9:33 of the first period. Benn worked the puck behind the net to Tyler Seguin, who in turn fed the 18-year-old Russian on Luongo’s doorstep for his second of the season. The Stars host the New York Rangers on Thursday.
