(My Sportsbook) - The Vancouver Canucks can become the first team to advance to the second round of the playoffs tonight when they try to complete a sweep of the St. Louis Blues in Game 4 of the Western Conference quarterfinals at Scottrade Center.

The Canucks won Games 1 and 2 on home ice and jumped out to the commanding 3-0 series lead with Sunday's victory in St. Louis. Should the Blues extend the series with a win tonight, Vancouver will get a chance to end the set Friday evening in front of the home crowd at General Motors Place.

After goaltender Roberto Luongo backstopped Vancouver to an impressive 3-0 win in Game 2, the Canucks had to work a bit harder for the victory in Sunday's 3-2 decision. Steve Bernier netted the game-winner early in the third period to help stake Vancouver to the three games to none edge.

Luongo, meanwhile, was solid between the pipes again, stopping 24 shots for the third-seeded Canucks, who have never swept a seven-game series in their history. Vancouver's lone playoff sweep came against Calgary in a five-game set during the 1982 Smythe Division semifinals.

St. Louis, which is in the postseason for the first time since 2004, was last swept in four games by Dallas in the 1994 conference quarterfinals.

Vancouver scored all three goals on the power play, with Daniel Sedin and Mattias Ohlund also lighting the lamp. The Canucks finished 3-for-5 on the power play and killed all six of the Blues' opportunities with the man advantage.

The Canucks won despite playing without centerman Mats Sundin, who is suffering from a lower-body injury suffered in Game 2. The Swedish star in questionable for tonight's game.

David Backes and Andy McDonald both registered a goal and an assist for the sixth-seeded Blues, who had won their last five on home ice to conclude the regular season, but failed in their attempt to win their first playoff game in St. Louis since beating San Jose on April 12, 2004.

Chris Mason made 23 saves in defeat and fell to 1-7 in his postseason career.

Paul Kariya, who hasn't played since November 5, has been skating for the Blues, but is not expected to be ready to make a return tonight. The veteran winger had hip surgery back in November after posting two goals and 13 assists in 11 games.

The Blues will have to battle history if they are to win this set as only two NHL teams have ever come back to win a series after falling behind three games to none. The last club to do so was the 1975 New York Islanders, who did it against Pittsburgh in the quarterfinals.

The Canucks and Blues have met twice prior in the postseason, with Vancouver winning both series in seven games. The Blues haven't played the Canucks in the postseason since a 2003 conference quarterfinals loss. The clubs split four meetings during this year's regular season.

The Blues had a 23-13-5 record at Scottrade Center this year, while Vancouver was 21-15-5 as the visiting club.
