Marian Hossa, with his first two goals of the series, and Patrick Kane , with his first, also scored, and rookie Corey Crawford made 36 saves for his first playoff shutout.
Since losing the first three games of the best-of-seven series, Chicago has dominated a Canucks team that it eliminated from the playoffs the last two seasons.
The Blackhawks won the fourth game 7-2 in Chicago, and return home for Game 6 on Sunday night looking to become the fourth team in NHL history to overcome a 3-0 series deficit.
Vancouver no longer looks like the team that won the Presidents’ Trophy with the best regular-season record. But there are lots of similarities to the squad that was knocked out the last two years while falling apart defensively.
Canucks goalie Roberto Luongo, pulled in the third period of Game 4 after giving up six goals, didn’t make it through the second period this time.
Luongo was pulled after giving up his fourth goal on 12 shots 1:26 into the second period, but it didn’t make a difference. Cory Schneider was beaten by the first shot he saw, Keith’s screened blast from the point.
Bruins 5 Canadiens 4, OT: In Montreal, Michael Ryder scored 1:59 into overtime to give Boston a victory over Montreal, tying the Eastern Conference series 2-2.
Ryder, the former Canadiens winger who also scored in the second period, took Chris Kelly’s pass from behind the net and shot past Carey Price to give Boston its second victory in a row at the Bell Center after the Bruins dropped the first two games at home.
Kelly brought Boston even for the third time in the game, scoring with 6:18 left in the third period. He put away a loose puck at his feet in the goalmouth for his second of the series.
Patrice Bergeron and Andrew Ference added goals for the Bruins. Tim Thomas made 34 saves.
Michael Cammalleri had a goal and two assists for Montreal, and Brent Sopel , Andrei Kostitsyn and P.K. Subban also scored. The Canadiens blew leads of 1-0, 3-1 and 4-3.
Game 5 is Saturday night in Boston.
Sharks 6 Kings 3: In Los Angeles, Ryane Clowe scored two goals, Jason Demers added another in the second period and San Jose beat Los Angeles to take a 3-1 lead in the Western Conference series.
Joe Thornton and Joe Pavelski scored in a 54-second span early in the third and Torrey Mitchell followed with his first goal of the playoffs to extend the Sharks’ lead.
They return to San Jose for Game 5 on Saturday night having swept the Kings on their home ice.
The teams combined for five goals in the second — two fewer than they scored in the middle period in Game 3, when the Kings blew a four-goal lead to lose 6-5 in their second overtime defeat of the series.
Antti Niemi made 35 saves while back in goal for the Sharks after being pulled for giving up four consecutive goals to the Kings before their collapse Tuesday.
Clowe and Demers scored 1:14 apart before Clowe added his second goal.
Clowe’s first goal capped a 2-on-1 when he scored behind Quick’s back at 3:58. Demers made it 2-0 when he beat a fully sprawled Jonathan Quick on the left side at 5:12. Both goals came with the teams skating 4-on-4 with Scott Nichol and Kings star defenseman Drew Doughty off for roughing.
Brad Richardson , Justin Williams and Alexei Ponikarovsky scored for the Kings.
