CHICAGO (AP) Charlie McAvoy scored 1:19 into overtime, and the Boston Bruins beat the Chicago Blackhawks 2-1 for their fifth straight victory. McAvoy finished a pretty passing sequence for the defenseman’s first goal of the season. David Krejci threw the puck outside to a streaking Jake DeBrusk, who made a perfect pass to McAvoy for the tap-in on the right side of the net. Chicago wasted a terrific performance by Robin Lehner, who made 38 stops in his first start since Jan. 21. The Blackhawks also lost defenseman Adam Boqvist to a right shoulder injury in the second period.
