Patrick Kane had a goal and an assist for the Blackhawks, who had only scored five goals total in the first three games of the series and hadn't gotten the puck past Rask in more than 129 minutes coming into Game 4. Bryan Bickell and Michal Rozsival had two assists apiece, and Corey Crawford made 28 saves for Chicago.
Patrice Bergeron scored twice, and Zdeno Chara and Jaromir Jagr each had two assists for Boston, which had won 11 of its previous 13 playoff games. Rask made 41 saves but he was screened on the game-winner, which quickly quieted the building where Boston had earned a dominating, 2-0 victory two nights earlier.
"One of things we have talked about, get pucks to the net," said Seabrook, a defenseman who also had the overtime goal in Game 7 of the Western Conference semifinals. "I just tried getting it on net, we had a great screen in front. ... It just found a way."
It was the third overtime game in the finals, but it bore little resemblance to the three tightly contested games that opened the series. The teams combined for five goals in the second period as many as in Games 2 and 3 combined as Chicago repeatedly sprinted into the lead only to have Boston come back and tie it.
The Blackhawks led 1-0, 4-2 and 5-4, but each time the Bruins evened it up, the last just 55 seconds after Chicago took the lead when Johnny Boychuk slapped it over a sliding Johnny Oduya with 7:46 left in regulation. Boychuk, who had never scored more than five goals in a season, has six in the postseason.
