BOSTON — The Flyers squandered all nine of their power-play chances Thursday night in their 2-1 overtime loss to the Boston Bruins in a preseason game at TD Garden.
Kenny Agostino won it on a breakaway with 1 minute, 40 seconds left in overtime.
Earlier in the OT, Claude Giroux hit the post and Val Filppula then hit iron on a breakaway. The puck went down the other end and Alex Lyon robbed Zach Senyshyn from point-blank range.
Defenseman Travis Sanheim, making a strong bid to earn a roster spot, scored a third-period goal and goalie Brian Elliott was flawless in two periods of work for the Flyers (1-1-2).
Sanheim “played a confident game tonight. He had the puck quite a bit,” coach Dave Hakstol said. “One of the things he’s good at is getting up in the play. His skating ability allows him to get there. I thought he did that very well tonight…and had a pretty clean game defensively as well.”
Elliott, in his first appearance with the Flyers since signing as a free agent in the summer, stopped all 18 shots he faced before being replaced by Lyon to start the third period.
With the teams skating four-on-four, Sanheim — who has been offensive-minded throughout the preseason — fooled goalie Tuukka Rask with a wrist shot from above the left circle, giving the Flyers and 1-0 lead with 15:03 left in regulation.
About 1½ minutes later, defenseman Paul Postma scored the equalizer for the Bruins (3-0).
The Flyers’ power play, which is directed by new assistant Kris Knoblauch, managed a total of just seven shots on their nine opportunities. Shayne Gostisbehere, the power-play quarterback, did not play.
“We have yet to work on it, so that’s not my greatest concern,” Hakstol said of the power play.
Hakstol was pleased with the team’s overall performance. They outshot the Bruins, 31-29, won 68.2 percent of the faceoffs, drew six more power plays, and had a 29-20 advantage in hits.
Elliott, in his Flyers debut, looked in midseason form.
“I felt pretty good. Just trying to see pucks and basically get acclimated to a game situation because I hadn’t seen that in camp at all,” he said. “Playing a game is fun. You forget how fun it actually is to play a game.”
Breakaways. The Flyers have a day off from camp Friday…..Radko Gudas had five hits and Sanheim had a team-high four shots…..Giroux won 20 of 25 faceoffs (80 percent) and Val Filppula won 10 of 11 (91 percent)…..The Flyers play a preseason game Monday against the Rangers at Madison Square Garden.
