Paul Stastny scored the game-winner, Dmitrij Jaskin broke a 16-game scoreless string, and Jake Allen made 21 saves to lead the St. Louis Blues to a 2-1 win over the Chicago Blackhawks in a Central Division showdown on Thursday night.
The Blues clinched the division title and home-ice advantage for the first round of the Stanley Cup playoffs with their second win over Chicago in five days. It's their first division title since 2011-2012 and only the third since 1986-87.
Jaskin poked a rebound past Alex Pietrangelo at 17:10 of the second period to break a scoreless tie. It was the Blues' first goal in 121 minutes, 58 seconds.
The power-play tally was set up when Chicago defenseman David Rundblad took a 4-minute penalty for high-sticking Jori Lehtera. Jaskin's last goal came March 1 in a 6-5 overtime loss to Vancouver.
Andrew Shaw scored for Chicago, which has lost three in a row but is guaranteed of opening the playoffs on the road and will finish third in the division.
Stastny converted on a 3-on-1 off a pass from Jaden Schwartz at 14:05 of third period for a 2-0 lead.
Shaw cut the deficit to 2-1 with his 15th goal of the season with 2:39 remaining.
Allen, who improved to 8-2-2 since Feb.1, stopped 38 shots in the Blues' 2-1 win Sunday in Chicago. His biggest save Thursday came early in the third period when he stopped Bryan Bickell from point-blank range while nursing a 1-0 lead.
Chicago goalie Corey Crawford made 23 saves and fell to 32-20-5.
