Patrick Kane and Jonathan Toews scored 3:28 apart in the first period, and the NHL-leading Chicago Blackhawks beat the Calgary Flames 3-1 on Friday night.

Marcus Kruger added a goal in the third period for the Blackhawks, who are 11-1-2 in their past 14 games. Chicago (36-6-5) will wrap up the regular season on Saturday at St. Louis.

Corey Crawford was sharp in making 25 saves and keeping the Blackhawks in the lead throughout. The only goal he allowed was Chris Butler's short-handed tally — Butler's first goal in 65 games.

Joey MacDonald stopped 35 shots in the final game of the season for the Flames (19-25-4), who failed to qualify for the playoffs for the fourth straight year.

The Blackhawks clinched the Presidents' Trophy, given to the NHL team with the best regular-season record, on Wednesday.
