Pavel Datsyuk banked in a shot from a bad angle off Chicago defenseman Nick Leddy for the winning goal 3 minutes 8 seconds into overtime, and the Detroit Red Wings beat the host Blackhawks, 3-2. After goalie Corey Crawford made two point-blank saves, Datsyuk got to the loose puck along the goal line to Crawford’s left, whiffed once and then snapped a rising shot that hit Leddy and bounded into the net.
