Vincent Trocheck, Jamie McGinn and Derek MacKenzie also scored for the Panthers.

Evgeni Malkin scored twice for the Penguins, and Carl Hagelin, Patric Hornqvist and Bryan Rust also tallied.

Dadonov one-timed a pass from Aleksander Barkov at 18:07 of the third for the game-winner.

Trocheck finished a 2-on-1 cross-ice pass from Denis Malgin after a breakout pass from Yandle to open the scoring early in the first period. Trocheck tapped in the pass at 3:44 for his team-leading 24th goal, and sixth in his last seven games.

The Penguins tied it when Hagelin beat Luongo, scoring his eighth goal at 12:40 to even it at 1-1.

Florida regained the lead at 19:21 when Dadonov collected a loose puck along the boards, beat Penguins defenseman Brian Dumoulin into the slot and zipped his 16th goal over Jarry's glove.

McGinn took a diagonal pass from Jared McCann and jammed in his eighth goal past Jarry's right pad at 2:07 of the second.

MacKenzie finished off a rebound from a Colton Sceviour at 8:12 for his third goal to give Florida a 4-1 advantage.

The Penguins then replaced Jarry with Matt Murray, who started in the club's 6-1 win over Carolina on Friday night.

Malkin scored his 35th goal when he chipped in a pass from Bryan Rust at 13:10.

Hornqvist had a goal overturned when it was ruled he pushed Luongo and the puck across the line late in the second.

Dadonov answered 58 seconds later when he one-timed a pass from Barkov for a 5-3 lead.

Hornqvist scored a power-play goal -- his 17th -- and Rust added his 10th just 49 seconds later to tie it at 5-5, before Dadonov's game winner three minutes later.
