Ivan Barbashev had a goal and an assist, and Charlie Lindgren made 26 saves for the Blues (17-8-5), who are 5-0-1 in their past six games and 8-0-1 in their past nine at home. St. Louis swept the home-and-home against Dallas, having won 4-1 on Tuesday.
"Winning is fun," Tarasenko said. "I think it's enough to say it's fun. The atmosphere, the mood, the confidence, it's great to keep winning. We have a tough trip coming up (beginning at the Winnipeg Jets on Sunday), so looking forward to [the] next game."
Lindgren became the first goalie to win his first five games for the Blues (four starts). Ryan Miller was 4-0-0 from March 2-8, 2014.
"A pretty cool thing," Lindgren said. "It's an individual award, but again, cliché, but it's a team award as well. The guys are battling hard for me. It isn't just about me, it's about the team. Very excited about it, but let's keep it going."
