BLACKHAWKS 3, RED WINGS 2 (SO): Patrick Kane scored the only goal of the shootout as visiting Chicago snuffed out Detroit's chances to earn the No. 4 seed for the postseason.
Corey Crawford stopped all three attempts in the shootout and made 30 saves for the Blackhawks, who saw their hopes of claiming the fifth seed disappear when Detroit's Pavel Datsyuk scored with 46.4 seconds left in regulation.
Viktor Stalberg and Andrew Shaw scored regulation goals for sixth-seeded Chicago, which will open the postseason on the road against the Pacific Division-champion Phoenix Coyotes.
Johan Franzen also scored for the Red Wings, whose loss clinched the No. 4 seed for the Nashville Predators. Nashville will host Detroit in the first round of the playoffs.
Patrick Sharp assisted on both goals for the Blackhawks, who won for the seventh time in the last eight meetings (7-0-1) in Detroit.
Stalberg put Chicago on top midway through the first period, shoveling a rebound through the pads of Jimmy Howard for his 22nd goal and third in four games.
Shaw doubled the lead late in the second period, but Franzen cut the deficit in half with his 29th goal eight minutes into the third.
Datsyuk's dramatic goal gave Detroit hopes of overtaking Nashville, which would have had to lose in regulation at Colorado later Saturday if the Red Wings won.
