Sean Monahan scored Calgary’s first goal at Boston in more than eight years, and the Flames earned their first road win against the Bruins since 2003 with a 4-3 shootout victory on Thursday night.

David Schlemko ended the shootout in the eighth round with a series of fakes on Boston goalie Tuukka Rask, who wasn’t ready for the last one as Schlemko tapped the puck into the net to clinch Calgary’s first win at Boston since December 2003.

Jiri Hudler and Johnny Gaudreau also scored for the Flames in regulation, and Karri Ramo made 34 saves, then allowed just one puck past him in the shootout when Patrice Bergeron scored to open the seventh round.

Brad Marchand and Milan Lucic scored for the Bruins, and Loui Eriksson added a third-period goal to tie at 3-all and force overtime.

Rask finished with 29 saves and helped Boston salvage a point by getting the game to overtime as Calgary pushed in the final minute of the third period.

Hudler tied it at 2-2 with 5:34 left in the second period when he slapped in a long rebound. Gaudreau gave Calgary its first lead on a wrist shot from the right circle that got through traffic and beat Rask 4:59 into the third period. Calgary’s second power-play goal of the game gave the Flames a 3-2 lead.

Eriksson, who shot wide on a one-timer with Ramo stuck on the opposite post earlier in the third, poked in a rebound to tie it with 9:16 left in the third. Chris Kelly had tipped the puck in on Ramo, who stopped it but couldn’t get to the rebound before it bounced to Eriksson.

Eriksson had a great chance to give Boston the lead again a few minutes later with a backhand, but Ramo dived across the crease and smothered the puck.

The Bruins committed three penalties in the last four minutes of the first period. Calgary converted on the second when Monahan scored with 1:11 left as Matt Bartkowski sat for hooking. Carl Soderberg’s hooking penalty with 16 seconds left carried over into the second. Boston was able to kill it, then regained the lead on Lucic’s one-timer 2:30 in.
