Chris Kelly scored the only goal of the second period as the Boston Bruins and Chicago Blackhawks are tied at 1-1 after two periods of Game 2 of the Stanley Cup Finals.
Boston had trouble sustaining any offensive pressure in the first and second periods, but Daniel Paille made a nice move behind the Chicago net to get around a defender and tried a wraparound that was stopped by Corey Crawford, but the rebound came out front and Kelly buried it with 5:02 to play.
Dennis Seidenberg was called for a trip on Brandon Saad with 2:49 to play in the second and Tuukka Rask stopped a Dave Bolland shot then covered up the puck as Patrick Kane threw it back out front.
Chicago caught a break as Paille picked off the puck and got it to Brad Marchand, who skated in on net with a defender on him and was able to get a shot off, but it caught the right post and stayed out.
A Johnny Oduya tripping call with 46 seconds to play gave the Bruins their second power play of the game, but Crawford made a couple of stops on Jaromir Jagr before time expired in the frame.
Boston will have 1:14 of power play time when the third period starts.
Rask has 22 saves through the first two periods while Crawford has turned away 11 shots.
Chicago had the only goal of the first period on Patrick Sharp's ninth of the playoffs.
Kane got the sequence started when he flew in on net from the right side and got a backhander on net then put his own rebound on Rask again. That started a mad flurry that saw Rask make two more saves, but Sharp chased down the puck at the right circle and his turnaround shot found its way through a maze and past a fallen Rask for a 1-0 lead with 8:38 left in the frame.
A wraparound from Jonathan Toews just over a minute later was reviewed to see if the puck crossed the line. It did apparently make its way across, but it was after the whistle had blown and the on-ice call of no-goal stood.
Chicago leads this series 1-0 after winning Game 1, 4-3, in triple-overtime on Wednesday.
