BOSTON -- Zdeno Chara scored two power-play goals and Jarome Iginla had a pair of assists against his former team to help the Boston Bruins beat the Calgary Flames 2-0 on Tuesday night.
David Krejci also had two assists and Tuukka Rask made 21 saves for the Bruins in their third straight shutout of the Flames in Boston. Rask picked up his third shutout of the season and extended Calgary's scoreless streak in Boston to 189 minutes, 36 seconds.
Reto Berra kept Calgary close, stopping 29 shots as the Bruins controlled play most of the game.
Boston outshot the Flames 31-21 one week after rallying for a 2-1 win in Iginla's return to Calgary, where he played 16 seasons and spent nine as the team's captain.
Iginla didn't get a point in his first game as a visitor against the Flames, but was a big part of the Boston power play Tuesday.
Krejci and Iginla set up Chara's slap shot from the point that beat Berra and put the Bruins ahead 7:38 into the second period. Lance Bouma was serving a double-minor for high-sticking, then was called for another high stick in the third shortly before Boston made it 2-0 on another goal by Chara.
Krejci started the play again with a pass to Iginla, whose shot from the left circle wound up between Chara's skates for an easy poke into the net with 16:41 left.
Iginla was traded to Pittsburgh last March, then signed with Boston as a free agent in the off-season.
NOTES: Boston forward Craig Cunningham made his NHL debut. ... Bruins forward Shawn Thornton, who is appealing a 15-game suspension for punching and injuring Pittsburgh's Brooks Orpik, did not play. ... The Flames have not scored in Boston since Oct. 19, 2006, when Alex Tanguay scored with 9:36 left in the third period.
