Anthony Beauvillier delivered a first-star performance on Wednesday night, scoring a pair of goals in the Islanders win.
The 22-year-old put the Isles ahead 2-0 with a power-play goal in the final minute of the first period, snapping a shot off Andersen's glove and in. He put the Isles ahead 3-2 at 16:43 of the second period, providing a halt to Toronto's second period momentum.
Between Beauvillier's goals, the Maple Leafs staged a comeback evening the score 2-2 just past the midway mark. Kasperi Kapanen put Toronto on the board with a backdoor play 43 seconds into the middle frame, while William Nylander tied it with a redirection off the rush at 11:22.
Toronto outshot the Islanders 13-6 in the second period, and with the momentum turning, Barry Trotz "jumpstarted" his lines, a move that allowed the Isles to pull ahead.
Trotz moved Brassard from the third line center back up to second line wing with Beauvillier and Brock Nelson, a line that was especially effective during Brassard's five-game goal streak. All three connected on Beauvillier's second of the night, with Nelson forcing a turnover on a Leafs' exit, Brassard feeding Beauvillier in front and the 22-year-old backhanding a shot five-hole on Andersen.
"He's hungry and it's been a lot of fun playing on his line," Brassard said of Beauvillier. "He's the engine on our line, he's the youngest one and we expect him to have the most every night. It's been a lot of fun playing with those two guys. Beau is one of our best players this season. Hopefully he can keep going that way. He's still a really young player in this league. He's still learning every day. He's going to be something in a couple years."
