With the point they received by reaching overtime, coupled with a loss by the Winnipeg Jets at Washington, the Islanders secured a place in the playoffs for the first time since 2007.
The Islanders earned a point for the 11th straight game (8-0-3).
CAPITALS 5, JETS 3
WASHINGTON -- The Washington Capitals clinched the Southeast Division title, completing a stark turnaround in a lockout-shortened season with a win over Winnipeg.
The Capitals blew a two-goal lead, survived a pair of replay reviews and exhaled deeply when defensemen John Erskine cleared two shots off the goal line. They also had to kill a late power play, but they held to win for the 10th time in 11 games.
Alex Ovechkin scored his NHL-leading 31st goal -- an empty-netter in the final minute -- and Matt Hendricks, Jason Chimera, Nicklas Backstrom and Mathieu Perreault also scored. Braden Holtby made 24 saves.
BLUES 3, AVALANCHE 1
ST. LOUIS -- Chris Stewart reached career milestones of 100 goals and 100 assists and St. Louis clinched a playoff berth with two games to spare, beating Colorado.
Brian Elliott made 17 saves two nights after getting yanked in a 5-3 loss at Colorado that squandered the Blues' first chance at clinching. St. Louis, which entered the game needing a point to qualify, scored two power-play goals for the first time in 32 games since Feb. 15 in the home-and-home rematch.
The Blues have made the playoffs in consecutive seasons for the first time since 2003-04. They have won four in a row at home to match their season best.
Cody McLeod scored his eighth of the season and fifth in five games for the Avalanche, who are an NHL-worst 3-16-4 on the road. Varlamov made 31 saves.
SHARKS 3, STARS 2
SAN JOSE, Calif. -- Logan Couture and Joe Pavelski scored goals 30 seconds apart late in the third period to help San Jose clinch its ninth straight playoff berth with a come-from-behind victory over Dallas.
Raffi Torres also scored for the Sharks, who moved into a tie for fourth place in the Western Conference with Los Angeles with two games remaining in the race for home-ice advantage in the first round. The Sharks visit the Kings in the season finale on Saturday.
Antoine Roussel and Loui Eriksson scored for the Stars, whose playoff hopes were dealt a serious blow. Dallas remains two points behind ninth-place Detroit and three behind eighth-place Columbus in the race for the final playoff spot. The Red Wings have a game in hand over both teams. The Stars end the season with home games against Columbus and Detroit.
PANTHERS 3, RANGERS 2
Goc broke a tie, and Drew Shore added a short-handed, empty-net goal to give Florida a 3-1 lead before the Rangers got back within a goal.
DEVILS 3, CANADIENS 2
New Jersey, which was eliminated from playoff contention on Sunday, dealt a blow to Montreal's hopes of winning the Northeast Division. The Devils (18-18-10) won for the third time in four games following a 10-game losing streak.
The sputtering Canadiens (27-14-5) lost for the fifth time in six games. They trail Boston by two points in the Northeast with only two games remaining.
FLYERS 5, BRUINS 2
The Flyers paid tribute to Boston in the Bruins' first road game since the Boston Marathon bombings.
SABRES 4, PENGUINS 2
Jochen Hecht also scored for the Sabres, who never trailed and snapped the Penguins' seven-game winning streak.
Pittsburgh center Evgeni Malkin assisted on Iginla's goal to pick up a point in his return after missing four games with a shoulder injury.
WILD 2, KINGS 1
Slava Voynov's shot from the far edge of the right circle was stopped by a sprawling Backstrom with 11 seconds remaining in the game to preserve the lead.
With a 3-7-1 record in the last 11 games since this month began and that playoff spot still unsecured, the Wild badly needed a victory.
The Kings failed to earn a point for only the third time in 15 games. They fell to 4-1-1 in their last six games. Jonathan Bernier, in the net for the first time in seven games in relief of Jonathan Quick, made 23 saves.
Backstrom stopped 22 shots.
