BOSTON — Sam Reinhart and Anton Lundell each scored twice for the Florida Panthers in a 4-3 win against the Boston Bruins at TD Garden on Monday.

Sergei Bobrovsky made 24 saves for Florida (2-2-0), and Adam Boqvist had an assist. Each of the defending Stanley Cup champions’ wins this season have come against the Bruins. The Panthers were playing the game without captain Aleksander Barkov (lower-body injury) and Matthew Tkahcuk (illness).

Mason Lohrei and John Beecher each had a goal and an assist for Boston (2-2-0). Jeremy Swayman made 22 saves, and Mark Kastelic had three assists.

Beecher gave the Bruins a 1-0 lead at 4:53 of the first period, redirecting Kastelic’s point shot through Bobrovsky’s five-hole.

Lundell tied it 1-1 at 6:37 of the first, jamming the puck over Swayman’s pads on the goal line after intercepting Lohrei’s behind-the-net pass.

Reinhart gave the Panthers a 2-1 lead at 11:51 with a power-play goal, beating Swayman stick-side off the faceoff.

Brandon Carlo tied it 2-2 at 5:08 of the second period with a wrist shot from behind the right circle.

Reinhart, playing in his 700th NHL game, gave Florida a 3-2 lead at 9:39 of the second with a short-handed goal. Reinhart stripped the puck from Bruins forward Matthew Poitras, rushed toward the net and fired a shot on Swayman, who made the save. The rebound eventually came to back to Reinhart, who slid it under the Boston goalie.

Lundell pushed it to 4-2 at 12:59 of the second period, picking up a loose puck along the right wall of the Bruins’ zone and beating Swayman five-hole, but Lohrei cut it 4-3 at 14:07 of the second with a shot from the left circle.

Trent Frederic nearly tied it on the power play at 12:58 of the third period, but his net-front shot hit Bobrovsky’s pad and fluttered up and wide. The Bruins are 0-for-9 on the power play across their past two games.
