Lucic opened the scoring just 59 seconds into the game when he went hard to the net and redirected David Krejci ‘s centering pass by Calgary  netminder Miikka Kiprusoff (26 saves) for his team-leading 25th goal of the season.
Brad Marchand  added some insurance 5:55 into the third when he gathered the puck in the right circle and wristed it under the crossbar for his 19th goal.
Curtis Glencross made things interesting with a power-play goal that cut the lead in half with 2:33 to go, but Lucic sealed the win with an empty-netter with 47 seconds remaining.
Thomas improved to 27-8-6 with the win and he continues to lead the NHL  in goals-against average and save percentage.
WHAT WENT RIGHT FOR THE BRUINS
-The Flames were hot coming in, having won three in a row and 11 of their last 14, but the B’s were able to pour some water on them and quiet the crowd early on. They got on the board less than a minute in when they caught Calgary in a line change. Adam McQuaid moved the puck up to Krejci to create an odd-man rush and Krejci faked a shot before centering for Lucic.
-Krejci continued his stretch of hot play, as he assisted on both of Lucic’s goals to give him six points in his last three games and 13 in his last 11. He had a goal and an assist in Thursday’s win over the Islanders and followed that up with two more assists in Friday’s win against the Senators.
-Marchand added to his impressive rookie season with his third goal in his last two games. The marker came as the result of hard work from the entire second line. Patrice Bergeron  forced a turnover with a hard check in the corner and then went to the net to redirect Andrew Ference ‘s shot right to Marchand, who was left with an open cage to shoot at.
-It seemed like there were bodies and pucks zipping around the front of the Boston net all night, but Thomas stood tall between the pipes. His biggest save came with a little more than four minutes left in the game when he flashed the leather and snagged Olli Jokinen‘s one-timer from the slot. It turned out to be even bigger than it appeared at the time given the fact the Flames scored less than two minutes later.
WHAT WENT WRONG FOR THE BRUINS
-Despite jumping out to a 1-0 lead, the B’s were outplayed for much of the first half of the game. The Flames were able possess the puck in the offensive zone for long stretches of play and maintain steady pressure on the B’s. They outshot Boston, 13-7, in the first period and built the lead to 21-12 by the middle of the second before the B’s picked it up and recorded five of the final six shots in the period.
-The B’s had a four-minute power play starting late in the second and carrying over to the third, but failed to score. It was a golden opportunity to up the lead to two and although the B’s created a few good chances, they couldn’t capitalize. It marked the first time in seven games Boston failed to score at least one power-play goal.
-With 3:04 to go, one of the last guys the B’s wanted in the penalty box was Bergeron, their top penalty-killing forward. But that’s exactly where he ended up after being called for a slash while pursuing the puck behind the Calgary net. The penalty ultimately cost Thomas his would-be league-leading eighth shutout.
