Blackhawks 3, Flames 1: Patrick Kane and captain Jonathan Toews continue to share the team lead after scoring their respective 23rd goals in the first period as host Chicago improved to 11-1-2 in its last 14 games.
Marcus Kruger scored to snap a 32-game goalless drought and defenseman Duncan Keith notched his 250th career assist. Corey Crawford turned aside 25 shots for the Presidents' Trophy-winning Blackhawks, who will wrap up their regular season on Saturday at Central Division-rival St. Louis.
Defenseman Chris Butler's short-handed tally ended a 64-game goalless stretch and Joey MacDonald made 35 saves for the Flames, who finished their season with three straight losses.
After his initial bid was denied by the stick of Calgary rookie defenseman Mark Cundari, Patrick Sharp retrieved the puck behind the net and fed Kane in the slot. Kane wristed the puck just inside the left post at 9:34 of the first period.
Toews tapped home a rebound nearly 3 1/2 minutes later to match Kane with his second goal in as many days. Butler answered midway through the second period as his blast from the point beat a screened Crawford for his first goal since Jan. 17, 2012, but Krueger countered with his first since Feb. 15 to regain the two-goal advantage.
