ST. LOUIS (AP) — 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. The power-play tally was set up when Chicago defenseman David Rundblad took a 4-minute penalty for high-sticking Jori Lehtera. Vladimir Tarasenko, the Blues' leading scorer with 36 goals, missed his fifth successive game with a lower body injury.
