Thanks to their second power-play unit, the Panthers tied the score with 17:02 remaining in the second. Rodrigues, left alone a couple of strides from the net, charged forward and jammed in a bad-angle goal.
Florida took a 2-1 lead on Samoskevich’s goal with 11:14 remaining in the second. The play started with Forsling’s shot partially blocked. Samoskevich picked up the loose puck with his back to the net. He then turned and fired, beating Talbot top shelf to the glove side.
The Panthers extended their lead to 3-1 with 3:39 left in the second. The play started when Forsling dove to break up a would-be breakaway by Patrick Kane. Six seconds later, Marchand scored, taking a pass ahead by Balinskis and then flipping the puck over Talbot’s glove.
Florida made it 4-1 with 5:57 left in the third as Barkov scored on a deflection. Jones had the primary assist.
