Tavares, who had two goals and an assist, reached the milestone when he gathered a rebound and scored into an open net with a backhand to make it 2-0 at 7:21 of the first period. He extended the lead to 3-0 at 19:53 on a one-timer from the right circle off a pass from Morgan Rielly.
"It's always more satisfying when a milestone]*
Mitchell Marner had a goal and an assist, Ron Hainsey had two assists, and Michael Hutchinson made 27 saves for Toronto (28-13-2), which went 3-0-0 against the Devils this season.
"Tavares and Marner are awesome to play with," said Maple Leafs forward Zach Hyman, who returned after missing eight games with a sprained ankle. "I just try and get them the puck as much as I can. [Tavares] is tenacious on it and you see how strong he is, how he gets the puck back all the time. He's one of the best finishers around the net in the League."
Blake Coleman and Brian Boyle scored, and Keith Kinkaid made 39 saves for New Jersey (16-20-7), which has lost three in a row.
"[Toronto] is a good team. Some of their strengths gave us some issues, and it's something we continually work on with our guys," Devils coach John Hynes said. "We need to be better in the hardness and intensity level around our net. That's where they do a good job. That's where Tampa Bay [Lightning] does a good job. Those teams are highly skilled and talented."
Coleman scored with a backhand off a rebound in front to make it 3-1 at 16:07 of the second period, and Boyle scored 26 seconds later on a rush off a turnover by Maple Leafs defenseman Jake Gardiner to cut it to 3-2.
