The Sharks are 8-7-2 as the visiting team this season and have split a pair of games so far on the current swing. San Jose dropped a regulation decision in Nashville on Wednesday, but rebounded with an overtime victory the following night in Dallas.
San Jose, which is currently two points behind Dallas for the Pacific Division lead, notched a 4-3 win over the Stars thanks to Logan Couture's power-play goal at the 1:20 mark of overtime. It was the Sharks' only goal on seven opportunities with the man advantage.
With Stars forward Mike Ribeiro off for a high-sticking double minor, the Sharks won a left-circle draw and the puck came back to Dan Boyle, who shifted from the left to right point. He dished back to Couture, who let fly from between the bottom of the circles for the winner.
"Our special teams tonight were below par," said Sharks head coach Todd McLellan. "He (Couture) found a way to get the winner and he's done that a number of times for us. When you have a player like that on your team, you have to be thankful."
Couture leads all rookies with 15 goals this year and is tied for the lead with 22 points. Five of his goals have been game-winners.
Devin Setoguchi scored twice and Torrey Mitchell also tallied for the Sharks. Joe Pavelski added two assists and Antero Niittymaki won after stopping just 15 shots.
The Sharks have played the last three games without defenseman Douglas Murray, who has been sidelined with a lower-body injury. He returned to practice earlier this week and is questionable for tonight's game.
The Blues are playing the middle test of a three-game homestand tonight and will try to build off Thursday's victory over the Los Angeles Kings. Alexander Steen scored the go-ahead goal with 2:53 left to play to help St. Louis beat the Kings, 6-4. The victory ended a two-game slide for the Blues, who were dealt a 5-2 loss the previous night in Detroit.
Vladimir Sobotka and David Backes both tallied a goal and two assists for the Blues. Brad Winchester andJay McClement both posted a goal and an assist in the win, while Eric Brewer added a goal.
"For our team to play back-to-back nights and put that type of performance out there to secure another win and secure another win in the conference is big for our club," St. Louis head coach Davis Payne said.
Ty Conklin turned aside 25-of-29 shots for the victors, including all 12 he faced in the final period. Jaroslav Halak, who is 2-0 with a 1.00 GAA in his two career starts against the Sharks, is expected to make his 25th start of the year tonight.
The Blues still have injury concerns on defense as both Erik Johnson and Alex Pietrangelo are questionable for this evening's game. Johnson left Wednesday's game against Detroit with a right knee sprain and could return tonight after missing just one game. Pietrangelo, meanwhile, has sat out the last two games for the Blues, but he may be able to return tonight.
Johnson leads the Blues in ice time this year and Pietrangelo is pacing St. Louis defensemen with 15 points.
St. Louis has an excellent 10-2-2 record at Scottrade Center this year.
San Jose played earlier this year in St. Louis and was handed a 2-0 loss by Halak and the Blues. The Sharks have still taken 10 of 14 overall in the series and have also won nine out of 12 in St. Louis.
