SAINT PAUL, Minn. -- Zach Parise ended a monthlong slump with a first-period hat trick, and that was all the offense the Minnesota Wild needed Thursday.

Minnesota jumped out to an early lead and held off the Calgary Flames, winning 6-2 to gain a critical two points in the race for the final playoff spot in the Western Conference.

Mikko Koivu added a trio of assists, Jared Spurgeon scored twice and Nino Niederreiter also scored for the Wild (36-28-11). With eight games to play, Minnesota leads Colorado by at least one point pending the outcome of the Avalanche's home game with the Philadelphia Flyers on Thursday.

The Wild will face the Avalanche in Denver on Saturday night.

Johnny Gaudreau and Jakub Nakladal scored for the Flames (31-37-6), who got 23 saves from goalie Niklas Backstrom in his return to his former home rink. Backstrom spent the first nine seasons of his career with the Wild before being traded to Calgary on Feb. 29.

Devan Dubnyk had 31 saves for the Wild, who won their fourth in a row.

Leading 4-2 in the third, Minnesota appeared to take a three-goal lead on a power-play shot by Matt Dumba. However, the Flames challenged the play, and after a review, it was ruled that Niederreiter made contact with Backstrom before the shot, so the goal was disallowed.

A few minutes later, the Wild made it 5-2 on a power-play goal that counted. Spurgeon slapped home a loose puck in at the left of the Calgary net. Niederreiter, playing in the 300th game of his career, added an exclamation point with under four minutes to play.

Backstrom, who is Minnesota's franchise goalie leader in games played (409), wins (194) and shutouts (28) got a standing ovation from the Wild fans when a tribute to him was played on the video board, and he responded with a stick salute.

Unfortunately for the Calgary goalie, the admiration came after Parise had already scored on two of Minnesota's first three shots on goal.

He opened the scoring after a pass from behind the net, popping off a high shot that glanced off Backstrom's left shoulder and into the net. The red goal light was a welcome sight for Parise, who has been battling nagging injuries and had scored just once in his last 16 games.

Parise doubled the Wild lead less than a minute later with a low shot that beat Backstrom between the knees. But Gaudreau's power-play goal near the midway point of the first period pulled the visitors back within one. Sean Monahan's shot from the right circle was wide of the net, but caromed hard off the end boards and went directly to Gaudreau at the left of the net. He scored on a high shot before Dubnyk could cover the far post.

Parise completed the hat trick before the first period was through, tipping a power play shot by Ryan Suter from his post at the top of the crease. It was the fastest three goals by one player in Wild history, and Parise's first hat trick at home as a member of the Wild.

After Nakladal scored on a rocket of a slap shot early in the second period to cut Minnesota's lead to 3-2, the Wild quickly got one back on a power play, when Spurgeon slapped home the rebound of a Parise shot.
