Roberto Luongo was ready from the instant the first puck dropped. He put last year’s playoff debacle at the United Center behind him, established his presence early and helped the Vancouver Canucks win their semifinal opener. Luongo had 36 saves, and the Canucks scored two momentum-shifting goals— one late in the first and one early in the second—to rout the Chicago Blackhawks 5-1 Saturday night. After clinching its opening-round series against the Kings last Sunday, the Canucks were raring to go. Luongo made 17 saves in the first period to set the tone. “It was nice to start that way. No doubt about it. That being said, it was only one game,” Luongo said. “I haven’t played in a week, so it was nice to get that kind of work early in the game, to get that comfort level back right away. After that I felt like normal.” Luongo gave up seven goals in his previous playoff appearance at the United Center a year ago when Chicago beat the Canucks in the clinching Game 6, including three to Patrick Kane(notes). Kane netted another goal Saturday night during a two-man advantage early in the third, but it came after the Canucks were already ahead 5-0. http://sports.yahoo.com/nhl/recap;_ylt=AivQsTmKLz4rlzJaKKcJn0l7vLYF?gid=2010050104
