The Sharks won in the Windy City for the first time in three seasons, claiming a 3-2 shootout victory Sunday as Logan Couture and Joe Pavelski each scored in the shootout while Sharks goalkeeper Alex Stalock stopped tries from Jonathan Toews and Patrick Sharp.

The Sharks got there with strong defensive play through 60-plus minutes in front of Stalock, who turned away 33 of 35 shots.

"It was the best defensive effort we've had in this building in a while," said Sharks coach Todd McLellan. "It's hard to play perfect, but we were pretty solid, solid in our zone, and our goalkeeper gave us a chance. Everybody contributed."

The shootout win snapped a six-game Sharks losing streak in Chicago dating back three seasons. Their last win over the Blackhawks here was a 5-3 decision on Dec. 30, 2010.

Right winger Brent Burns forced a 2-2 tie with a third-period goal, and the teams played through the balance of regulation and overtime deadlocked.

Couture collected his 21st assist in the first period at the 10:12 mark as he lined a feed from in back of the net to defenseman Jason Demers, who fired past Chicago goalie Corey Crawford for his third goal of the season and a 1-0 lead.

After a scoreless second period, Chicago tied the score on defenseman Niklas Hjalmarsson's fourth goal, a slap shot past Stalock at 1:27 of the third.

The Blackhawks took a 2-1 lead at 4:01 on Michal Rozsival's long shot from a step inside the blue line. It was his first goal of the season.

Burns' 14th goal of the season came at the 11:10 mark of the third period, on assists from center Joe Thornton and defenseman Marc-Edouard Vlasic.

"You've got to be competitive against these guys, that's all it was," Thornton said. "We didn't shoot good in our last game here, and we wanted to show them how good we are."

Stalock started after relieving Antti Niemi in a 4-3 loss Saturday at Colorado.

"Al's been good," Pavelski said. "He comes in on those back-to-back nights, and that's not easy. He's played well when he comes in, and you've got to give him a lot of credit."
