ST. LOUIS — 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 playoff series on Thursday night.

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.

“It’s big. We want to start this series off on a good note,” Steen said. “Especially at home in front of our fans.”

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.
