Iginla scored twice to reach the 30-goal mark, and Patrice Bergeron added a goal as the Bruins won for the 14th time in 15 games. Chad Johnson made 31 saves, and he and Tuukka Rask have combined to allow only 13 goals over 11 games.
DENVER (AP) - Semyon Varlamov had a season-high 47 saves and Colorado clinched its first playoff berth in four years by beating San Jose.
Center John Mitchell had a goal and an assist for the Avalanche, who moved past Chicago into second place in the Central Division with 100 points in what might have been a costly victory.
Center Matt Duchene injured his knee injury on the opening shift Saturday when he collided with teammate Jamie McGinn near the Sharks' blue line. He fell to the ice and then gingerly skated to the bench.
Mitchell moved up to center Colorado's top line, and came through with a big power-play goal to give Colorado a 3-1 lead at 6:32 of the second period.
GLENDALE, Ariz. (AP) - Zach Parise scored two of Minnesota's three third-period goals and the Wild rallied to beat Phoenix in a game with playoff implications.
Phoenix nursed a 1-0 through two periods on Mikkel Boedker's early power-play goal, but the Coyotes went 24:28 without a shot.
Parise tied it from the top of the circle off a face off 8:03 into the final period, then Jared Spurgeon scored on a slap shot from the top of the right circle with 7:03 to play and Parise added an empty-net goal in the final minute.
The Wild pulled three points ahead of Phoenix for the No. 7 spot in the Western Conference. The Coyotes are just a point ahead of Dallas for the No. 8 spot.
RALEIGH, N.C. (AP) - Ryan Johansen scored a power-play goal at 2:40 of overtime and Columbus beat Carolina to earn two points in its push for the second playoff berth in club history and first since 2009.
Brandon Dubinsky rang the left post midway through the extra session for the Blue Jackets. Goalie Anton Khudobin couldn't cover the puck, but forward Jiri Tlusty did - drawing the Hurricanes' first penalty of the night at 1:54.
Johansen then ended it with a snap shot that trickled past Khudobin.
ST. LOUIS (AP) - Colton Sceviour got the first two goals for Dallas and Antoine Roussel scored on a breakaway in the third period to secure the victory over St. Louis.
Cody Eakin had a goal and assist and Kari Lehtonen was strong in net for the Stars, who have won four of five in pursuit of a Western Conference playoff spot.
Dallas entered the day three points out of a playoff spot before winning for the second straight night and saddling the Blues with just their sixth regulation home loss.
Alex Steen had a pair of power-play goals for the Blues, who had been 8-0-2 in their previous 10 at home including an overtime loss to Dallas earlier this month. St. Louis fell one point behind Boston for first place overall in the NHL.
Pacioretty's second goal put the Canadiens ahead 3-0 in the second period. Pacioretty camped at edge of the crease and tipped in a pass from Desharnais at 14:00 for his 35th of the season, a career high. Pacioretty has 11 points in his past 10 games.
