BOSTON _ Carter Hart has made watching the Flyers fun again.
The unflappable rookie goalie has beaten the great Pekka Rinne, has won in the center of the hockey universe, Montreal, and on Thursday, he bested another great NHL goaltender as the Flyers rallied past Boston in overtime, 3-2, at TD Garden and won their sixth straight.
Hart made 25 saves, the Flyers dominated the play after the first period, and Travis Sanheim scored the winner with 2 minutes, 4 seconds left in overtime. Sanheim scored on a power-play wrist shot from the top of the left circle as Wayne Simmonds set a screen in front.
The loss prevented Tuukka Rask from becoming the winningest goalie in Boston's history. He is tied with Cecil "Tiny" Thompson (252 wins).
The Flyers, who got a pair of assists from Jake Voracek, outshot the Bruins, 41-25.
Boston right winger David Pastrnak is making a lot of scouting directors and general managers sorry they allowed him to slip to 25th overall in the 2014 NHL draft in Philadelphia.
Pastrnak, 22, who was selected eight picks after the Flyers took Sanheim, scored twice Thursday and reached the 30-goal mark for the third straight season.
But it wasn't enough.
Rask, who returned from a concussion suffered Jan. 19, made 38 saves.
Rask stopped Scott Laughton's penalty shot with 13:18 left in regulation to preserve Boston's 2-1 lead. Laughton had been pulled down on a breakaway by John Moore.
But the Flyers got the equalizer on Oskar Lindblom's power-play deflection of Voracek's shot with 9:24 remaining. The Flyers' power play, last in the league (12.9 percent success rate entering the game), had been just 2 for 25 in their previous nine games.
In the OT, they capitalized on Brad Marchand's penalty.
The Bruins' precision-like power play, meanwhile, is one of the main reasons they are in a playoff spot, and it created the early lead Thursday.
Pastrnak took a slick cross-ice feed from Torey Krug and scored on a one-timer from deep inside the left circle, putting the Bruins ahead, 1-0, with 16:55 left in the first. It was Pastrnak's 15th power-play goal, tops in the NHL this season.
The Bruins controlled most of the first period, but the Flyers tied the score when Claude Giroux took a pass from Voracek and beat Rask on a breakaway with 43.2 seconds left in the session.
For Giroux, who was in the penalty box when Pastrnak scored the game's first goal, it was his 15th tally _ and 10th on the road.
"We weren't playing our best hockey in that period," Giroux said. "I think we were sitting back a little too much, but being able to tie it up was huge for us."
The Flyers gained momentum from the goal and pressured the Bruins early in the second, but Rask made a handful of saves, including a point-blank stop on Lindblom. Rask has dominated the Flyers in his career, entering the game with a 14-2-3 record, a 1.99 goals-against average, and a .930 save percentage against Philadelphia.
Boston regained the lead, at 2-1, on a deft tip-in by Pastrnak, who deflected the puck past Hart despite having defenseman Robert Hagg in his face with 14:49 to go in the second.
The Flyers had a 17-7 shots advantage in the second period, but Rask had all the answers. So did Pastrnak.
The Flyers will next have to deal with one of the NHL's other top scorers, Connor McDavid, when they host Edmonton on Saturday afternoon and start a five-game homestand.
