CHICAGO (AP) - Brent Seabrook sent a wrist shot past goalie Jimmy Howard's glove 3:35 into overtime to give the Chicago Blackhawks a 2-1 victory over the Detroit Red Wings in Game 7 of their second-round playoff series on Wednesday night. The Blackhawks, who had the best record in the NHL regular season, rallied from a 3-1 series deficit to reach the Western Conference finals against the defending Stanley Cup champion Los Angeles Kings. Seabrook picked up a loose puck and skated in on Howard through the middle of the ice, with Detroit defenseman Niklas Kronwall in front of him. His shot appeared to hit Kronwall's leg before it sailed into the left side of the net for the Chicago defenseman' first goal of the postseason. The sellout crowd of 22,103 roared as Seabrook skated over to the boards and was mobbed by his teammates.
