VANCOUVER—Marian Hossa wasn’t sure if the Blackhawks have gotten back in Vancouver goalie Roberto Luongo’s head. But they are back in their series with the Canucks. Defenseman Duncan Keith had two goals and two assists and the Blackhawks stayed alive in their Stanley Cup title defense, routing Vancouver 5-0 on Thursday to cut the Canucks’ lead to 3-2. Marian Hossa, with his first two goals of the series, chased Luongo early in the second period as the Blackhawks have bounced back impressively after losing the first three games of the series. Since then, the Hawks have dominated a Canucks team that it eliminated from the last two playoffs, outscoring them 12-2.Patrick Kane also scored his first goal of the first-round series for the Blackhawks, who return home for Game 6 on Sunday night looking to become the fourth team in NHL history to overcome a 3-0 series deficit. Corey Crawford had 36 saves for his first playoff shutout. 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. Luongo, pulled in the third period of Game 4 after giving up six goals, didn’t make it through the second period this time. He 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 point blast through traffic, the second like that for the defender.The Hawks played a second straight game without rugged defenseman Brent Seabrook, who sustained a concussion when he was shouldered in the head by Raffi Torres in Game 3, a blow the Blackhawks felt deserved a suspension. They rallied behind Seabrook’s absence — and Torres presence — in Game 4, and again Thursday, with Seabrook’s normal defensive partner, Keith, leading the way. After Crawford robbed Alex Burrows on an early power play, Hossa, who only had one assist in the series, walked untouched into the high slot late in a Hawk advantage and snapped a shot past Luongo’s glove 5:54 into the game.Keith doubled the lead 17 seconds later with a screened point shot, and a power-play point shot was tipped in by Kane — his first goal of the series — for a 3-0 lead six minutes after that. Hossa ended Luongo’s night on a breakaway early in the second period, and Keith added his second goal — and fourth in three games.Canucks captain Henrik Sedin was quick to point out his team was still up 3-2 in the series. It just didn’t feel that way to anyone watching the last two.

NOTES— This is the 18th time the Blackhawks have lost the first three games of playoff series, but the first time the Blackhawks have battled back to force a Game 6….Crawford also had an assist, his second of the series, giving him more points than several key Canucks forwards….Vancouver made roster adjustments from Game 5, with Aaron Rome in for Keith Ballard, an apparent healthy scratch, as the sixth defenseman….C Cody Hodgson was back on the third line, and Torres was dropped down to the fourth line in place of LW Victor Oreskovich.
