VANCOUVER—The Canucks’ top line of Henrik and Daniel Sedin with Alex Burrows combined for nine points, and Roberto Luongo made 43 saves.Yet, the biggest story of Vancouver’s 5-1 victory over the Blackhawks on Saturday night may have been the three unheralded defensemen pressed into action because of injuries.With defensemen Sami Salo, Willie Mitchell and Kevin Bieksa all hurt, the Canucks got key minutes out of Aaron Rome, Brad Lukowich and Nolan Baumgartner while slowing down the NHL’s third highest scoring team.Rome was a healthy scratch 22 times this season and spent two weeks in the AHL, Lukowich was in the minors until January, and Baumgartner played his first game in the NHL since the 2006-07 season. Combined, they were plus-6 against the Hawks.Vancouver was outshot 44-28, but kept most to the outside. The Canucks prevented many quality chances and odd-man rushes for the potent Blackhawks while Mikael Samuelsson, Henrik Sedin and Steve Bernier staked them to a 3-0 lead in the first period.Jonathanc Toews scored 3:30 into the third period, but Henrik Sedin added his second goal 32 seconds later. He also set up twin brother Daniel on a 2-on-1 rush with 1:26 left to round out the scoring as Vancouver won its fourth straight to move into a tie with Colorado atop the Northwest Division.Daniel Sedin also had two assists, and Burrows had three to extend his point streak to 11 games (13 goals, 5 assists). Henrik Sedin also pushed his NHL-leading point total to 74, but Canucks coach Alain Vigneault was as impressed with when his top line scored as how much it did. Antti Niemi got consecutive starts ahead of No. 1 goalie Cristobal Huet for the first time all season, but didn’t last long. Huet started the second period after Niemi gave up three goals on 12 shots.Huet stopped 14 of 16 shots as the Hawks lost in regulation for just the fourth time in 17 games and dropped to 3-2 on a season-high, eight-game road trip. Despite the depleted defense, Luongo only needed a handful of great saves. He got a glove on Patrick Kane’s shot 19 seconds in, stopped backhanders by Ben Eager in close twice on the same play midway through the second, and made a fully extended glove save off Cam Barker’s power-play drive early in the third.

NOTES—Salo (groin) and Mitchell (upper body) are day to day, but Bieksa (lacerated ankle tendon) is out indefinitely.,,,,,Canucks C Pavol Demitra’s assist on Bernier’s goal was his first point in four games since missing nine months with a shoulder injury sustained against the Blackhawks in the second round of last year’s playoffs…..Niemii, who beat the Canucks 1-0 win on Nov. 22, came in with a better goals-against (1.85 to 2.24) and save percentage (.923 to .904) than Huet….Vancouver C Rick Rypien missed a third game (flu).
