Thursday’s Three Stars: Perfect Mason; Canucks clinch Presidents’ Trophy

No. 1 Star: Chris Mason, Atlanta Thrashers

With their slim playoff lives on the line, the Thrashers stayed alive with a 1-0 shutout of the Philadelphia Flyers thanks to Mason's 43-save night and Nik Antropov's goal midway through the third period. The shutout was the 21st of Mason's career and boosted the Thrashers to 7-4-1 in their last 12 games and 3-1 against the Flyers this season.

No. 2 Star: Joffrey Lupul, Toronto Maple Leafs

Another team with their playoff aspirations hanging by the thread, the Maple Leafs beat the Boston Bruins 4-3 to win in a shootout as Lupul contributed two tying goals on the night and added an assist. Nazem Kadri scored the only goal in the shootout as Toronto sits five points behind the New York Rangers and Buffalo Sabres for the eighth spot with four games to play.

No. 3 Star: Colin Greening, Ottawa Senators

Recording his first multi-goal game, Greening's pair helped the Senators sweep their season series with Florida in a 4-1 victory and send the Panthers to their seventh straight defeat. Greening came close to notching a hat trick, but he shanked a feed from Jason Spezza in the second period and was later denied by Scott Clemmensen in the third. He also led all players in shots with five.

Honorable mention: After finding themselves down 1-0 after the first period, the New York Islanders scored six straight goals en route to a 6-2 win over the Rangers. P.A. Parenteau, Radek Martinek and Matt Moulson each scored a goal and an assist, while Al Montoya made 25 saves in the win. Dylan Reese recorded a career-high three assists ... Martin St. Louis hit the 30-goal mark for the sixth time in his career as Tampa Bay slipped by the Penguins 2-1 and clinched a playoff spot for the first time since the 2006-07 season ... Niklas Backstrom made 33 saves and snapped a personal six-game losing streak as Minnesota downed Edmonton 4-2 ... Tom Gilbert's goal was his 500th NHL point ... Your "Fight of the Night" goes to Jay Rosehill and Milan Lucic for this intense scrap that turned into a boxing match:

Did you know? Niklas Backstrom is 14-0-0 lifetime against the Edmonton Oilers.
