BOSTON — Brent Seabrook’s goal 9 minutes 51 seconds into overtime lifted the Chicago Blackhawks to a wild 6-5 victory over the Boston Bruins on Wednesday night and tied the Stanley Cup finals through four games.
Seabrook fired a 45-foot shot past Bruins goalie Tuukka Rask to end Game 4 and send the series back to Chicago tied, 2-2.
Seabrook also scored the overtime goal in Game 7 of the Western Conference semifinals to eliminate the Detroit Red Wings.
Only 12 total goals were scored in the first three games before the teams combined for 11 on Wednesday night.
Game 5 of the best-of-seven series is Saturday night.
It was the third overtime game of the series. The Blackhawks won the opener, 4-3, in three overtimes, and the Bruins won, 2-1, in the first overtime period in Game 2.
Boston grabbed the series lead Monday night with a 2-0 victory behind Rask’s third shutout of the postseason.
Seabrook’s shot from the right went to the far side of Rask, who appeared to be screened.
Trailing 4-3 after the second period, the Bruins tied it on Patrice Bergeron’s second goal of the game at 2:05 of the third period.
Patrick Sharp gave Chicago a 5-4 lead at 11:19 of the third period with the Blackhawks’ first power-play goal in 30 chances, but Boston came right back to tie it 55 seconds later on Johnny Boychuk’s hard 40-foot shot.
All five Bruins goals were to the glove side of goalie Corey Crawford.
Jonathan Toews broke his scoring slump in Chicago’s three-goal onslaught in the second period against Rask.
In an unusually wide-open game, the teams combined for five goals in the second period after the first ended in a 1-1 tie on goals by Chicago’s Michal Handzus and Boston’s Rich Peverley.
Patrick Kane and Marcus Kruger also scored for Chicago in the second. Milan Lucic and Bergeron countered for Boston.
Rask posted his third shutout of the postseason in Game 3 and began Game 4 with a shutout streak of 122 minutes 26 seconds.
That ended at 129:14 when Handzus scored a short-handed goal at 6:48 of the first period. Then Peverley, who had been struggling offensively, scored his second playoff goal during a rare power-play shift for him at 14:43.
The Blackhawks, Stanley Cup winners in 2010, dominated the early part of the first period. But the Bruins, the 2011 champions, came on strong in the last 10 minutes and ended the period being outshot by only 10-9.
Marian Hossa returned to the Blackhawks lineup after being a late scratch in Game 3 because of an upper body injury. He has two game-winning goals in the playoffs and was second on the team with 17 goals during the regular season.
Since the best-of-seven format for the Cup finals began in 1939, teams leading 2-1 have won the championship 38 of 47 times.
Boston had won its previous seven home playoff games, outscoring opponents, 21-10. The Bruins are 11-3 in their past 14 games with all three losses coming in overtime.
Rask has allowed one goal or fewer in each of Boston’s past eight wins.
