How it happened: Goals were difficult to come by for both teams in Games 2 and 3, but that all changed on Wednesday. The Blackhawks and Bruins couldn't stop scoring in Game 4. Brent Seabrook broke a 5-5 tie with the winner in overtime. It all started when the Blackhawks took a 1-0 lead when Brandon Saad stole the puck from Bruins forward Tyler Seguin and set up Michal Handzus for a short-handed goal at 6:48 of the first period. A Saad turnover would be partly responsible for the Bruins answering with a power-play goal by Rich Peverley at 14:43 of the first period. The Blackhawks went ahead 3-1 in the second period with consecutive goals by Jonathan Toews and Patrick Kane. Milan Lucic cut the Blackhawks' lead to one at 14:43, but the Blackhawks scored less than a minute later with a goal by Marcus Kruger. With the Blackhawks up 4-2, Patrice Bergeron emerged for the Bruins. He scored on a power-play goal at 17:22 of the second period and tied the game at 4-4 at 2:05 of the third period. Patrick Sharp put the Blackhawks back ahead shortly with a power-play goal at 11:19 of the third period. Less than a minute later, Bruins defenseman Johnny Boychuk tied the game. Neither Blackhawks goaltender Corey Crawford nor Bruins goaltender Tuukka Rask had previously allowed more than four goals in a playoff game this season.
Player of the game: Seabrook came through again. It was his second winner of the playoffs this season.
What it means: The Blackhawks evened the series at 2-2 and regained home-ice advantage. The Blackhawks had scored just two goals in the past two games. One reason the Blackhawks broke out of their slump was Blackhawks coach Joel Quenneville reunited Toews and Kane. They had two goals and one assist on Wednesday. It was just Toews' second goal of the playoffs. The Blackhawks' power play also converted for the first time in the series. They're 1-for-15 in the series. The goal snapped the Bruins' streak of 30 consecutive penalty kills. The Blackhawks improved to 4-5 on the road in the playoffs this season, and the Bruins fell to 7-3 at TD Garden.
What's next: The series moves to Chicago for Game 5 on Saturday. The Blackhawks are 10-2 at the United Center in the playoffs this season. The Bruins are 6-3 on the road.
