Jonathan Toews scored the only goal of the second period to bring Game 6 of the Stanley Cup Finals between the Boston Bruins and Chicago Blackhawks to a 1-1 tie entering the final period.
Chicago holds a 3-2 lead in this series after taking the past two games, including a 3-1 win at home on Saturday.
Boston had a power play carry over from the first period to start the second, and was awarded its third advantage of the game at 2:24 after Andrew Shaw was called for roughing, but the team wasn't able to add to its advantage and Chicago tied the game as soon as it expired.
A neutral zone faceoff just outside of the Chicago end was won by Boston, but Zdeno Chara couldn't control the puck and Toews stole it off him.
Skating into the Boston end down the right wing on a 2-on-1, Toews fired the rolling puck between the five-hole of Tuukka Rask for his third of the playoffs at 4:24.
Chicago kept taking penalties as Brent Seabrook was whistled for tripping David Krejci behind the Chicago net at 5:12, but Corey Crawford kept the game tied by stopping a Brad Marchand stuff attempt from the right side.
The Blackhawks got their first power play of the game when Tyler Seguin was called for hooking Bryan Bickell during a sequence in the Boston end at 13:57.
Chicago, which was 1-for-17 on the power play coming into the game, had one good chance during the advantage on a Patrick Sharp slap shot from the left point. Rask made the save and the puck briefly stayed in front, but it was cleared away and Boston kept the puck away from the net during the rest of the advantage.
Crawford, who faced 12 shots in the first period, turned away all six shots he saw in the second period, while Rask had 14 saves through the first two periods.
It was all Boston in the first period, and the team took a 1-0 lead just 7:19 in.
Off a right-circle faceoff after Crawford covered up a Chris Kelly rebound chance in front, Boston eventually got control of the puck and Daniel Paille had the disc at the left point.
Paille fed the puck down low and it went into the air, but Seguin was able to grab it and dropped it to the ice before backhanding a pass to the right, where Kelly one-timed it in for his second of the playoffs.
The Bruins continued to pepper Crawford with shots. A blast from the high slot by Johnny Boychuk with traffic in front was stopped, but Johnny Oduya was called for hooking Seguin on the play and the Boston power play went to work.
Crawford again stood tall, as he blocked a left-point shot from Krejci, then turned away Nathan Horton on the rebound. Later in the advantage, Milan Lucic was in the clear for a shot from the low slot, but Seabrook blocked it away.
Boston got its second power play of the game with 1:35 left in the first period after Michal Rozsival was called for high sticking on Marchand.
