Alexander Steen scored at 26 seconds of the third overtime to give the St. Louis Blues a 4-3 victory over the defending Stanley Cup champion Chicago Blackhawks in Game 1 of their first-round Western Conference playoff series on Thursday night in St. Louis.

Steen beat Corey Crawford off a pair of short passes from Steve Ott and David Backes to cap the longest overtime game in franchise history.

Ryan Miller blanked the Blackhawks after Patrick Kane scored on a breakaway to put Chicago up 3-2 late in the first period and Jaden Schwartz tied it with 1:45 to go in regulation.

The Blues have had to kill two Chicago power plays, one in each of the first two OTs. What's more, Miller stopped Chicago's Patrick Sharp on a clear-cut breakaway with 2:40 remaining to play in the second OT.

Avalanche 5, Wild 4: Paul Stastny scored 7:27 into overtime after tying the game with 13.4 seconds remaining in regulation in Game 1 of the the Western Conference series. Gabriel Landeskog, Ryan O'Reilly and Jamie McGinn also added goals for Colorado in Patrick Roy's postseason debut behind the bench.

Rangers 4, Flyers 1: Brad Richards and Derek Stepan scored power-play goals 47 seconds apart in the third period, and New York beat Philadelphia in the playoff opener to stretch its home-winning streak over the rival Flyers to nine games. The teams were locked in a 1-1 tie when Jason Akeson -- playing in just his third career NHL game -- was given a double high-sticking penalty for clipping Rangers forward Carl Hagelin with 7:35 remaining.

New York quickly took advantage. Richards gave the Rangers their first lead of the night when a rebound of Martin St. Louis' shot came to him, and he fired it in from the right circle, punctuating the moment with an emphatic fist pump at 8:22. Richards and St. Louis hooked up again to help set up Stepan's insurance goal.

Ducks-Stars: A day after Anaheim captain Ryan Getzlaf took a slap shot to the head, the Ducks had already found the lighter side of a potentially disastrous playoff injury.

"Luckily, he's married, has a couple of kids," Anaheim defenseman Ben Lovejoy said. "He's not trying to impress anybody with his face." Nobody in either dressing room was surprised to learn Getzlaf plans to play against the Dallas Stars in Game 2 on Friday night despite that huge cut on his face. Getzlaf was hit by Tyler Seguin's shot in the final minute of the Ducks' 4-3 victory over Dallas on Wednesday night in the series opener, but the puck apparently broke no bones.
