TORONTO -- Auston Matthews scored twice for the Toronto Maple Leafs in a 7-1 win against the New York Islanders at Air Canada Centre on Tuesday.
Frederik Andersen made 33 saves for his 100th NHL win.
"I thought he was real solid. I thought they were heavy, we didn't execute great early," Maple Leafs coach Mike Babcock said. "We played good defensively, but they were heavy. I thought Freddie made some real good saves. The better the goalie plays, the more you settle down and the more you dial in. We scored timely goals, and then it got to be a real good situation for us because most games in this league you're grinding right till the bitter end."
Toronto (26-18-11) leads New York (25-20-10) by three points for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.

"As much as it's just one loss, that's a humbling loss, that's [a butt] kicking, I'm sorry," Islanders coach Doug Weight said. "They played a playoff game tonight; we played a hard game but we didn't play a playoff game. That's virtually what it was, right? We win, we're in the playoffs as far as statistically speaking."
Toronto allowed a goal in the first five minutes in five of its past seven games but on Tuesday took a 2-0 lead in the first period.
Josh Leivo scored his first goal of the season, in his fifth game, at 11:36 to make it 1-0. The Maple Leafs went up 2-0 with 32 seconds left when Nikita Zaitsev's shot from the point deflected off Nazem Kadri for his 21st goal of the season, an NHL career high.

Kadri put a shot on net from the left-wing boards that was saved by Thomas Greiss, but the rebound went off William Nylander for a 3-0 lead at 9:26 of the second period.
Islanders forward Jason Chimera was stopped by Andersen on a breakaway at 16:55 of the second period, but Chimera was awarded a penalty shot because of a hooking call on Matt Hunwick. Chimera scored his 14th goal of the season to make it 3-1.
Matthews made it 4-1 at 5:41 when he backhanded a shot over Greiss, and Tyler Bozak made it 5-1 at 7:16.

After Matthews scored his 27th goal of the season at 11:51 for a 6-1 lead, Greiss was pulled for Jean-Francois Berube. Greiss allowed six goals on 34 shots.
Matt Hunwick scored his first of the season at 15:40 for a 7-1 lead.
Goal of the game
Defenseman Adam Pelech turned over the puck in the Islanders zone to Maple Leafs forward Josh Leivo, who put a wrist shot past Greiss' glove.
"It feels good," Leivo said. "Obviously I had that empty net at the start that I missed on. I was fortunate enough to get another chance and it just feels great. It's been a lot of hard work."

Unsung performance of the game
The Maple Leafs got caught out of position at 10:04 of the second period and gave up a 2-on-1. Islanders center John Tavares was the puck-carrier and tried to make a cross-ice pass, but defenseman Morgan Rielly sprawled to get a stick on it and deflect it out of play.
They said it
"You hope so, obviously that's the plan. There's so many games in general that you just have to turn the page. Obviously you lick your wounds a little bit tonight, review how we can be better tomorrow, and try to make some adjustments. Everyone be a little sharper, a little better, probably a little grittier than we were tonight for our next game." -- Islanders captain John Tavares
"It's nice, but it's more important for the 26 we have as a team here this year. I think that's what we worry about here, that's what we enjoy." -- Maple Leafs goaltender Frederik Andersen on his 100th NHL win
