Those saves proved important, as Leafs opened up a 2-0 lead by the end of the first period. Leivo beat Thomas Greiss (28 saves on 34 shots) low blocker 11:36 and Nikita Zaitsev's shot caromed off Kadri and past Greiss at 19:28.
"They got some bounces and we didn't," Chimera said. "We hit a couple of posts in the first period and I thought we deserved a little better the first couple of periods anyways."
Andersen was the difference again in the second period, as the Islanders outshot the Leafs 16-11 in the middle frame. Greiss' attempt to steer a Kardi shot aside deflected off a crashing Nylander to make it 3-0 at 9:26, but the Islanders got on the board before the end of the period. Matt Hunwick clipped Chimera on a breakaway at 16:55, leading to a penalty shot, which the 37-year-old sniped top corner over Andersen's blocker.
Chimera's 14th of the season gave the Islanders a spark at the end of the second period, but Matthews scored the crucial next goal to start the third, dismantling the Islanders' comeback bid. Toronto added three more goals before the end of the contest, as Tyler Bozak, Matthews beat Greiss, while Hunwick scored on JF Berube, who stopped 6-of-7 shots in relief.
"It could have been tied up after two periods and the third period kind of got away from us," Chimera said. "You just have to write some games off. It's hard to do this time of year, you have to get two points… You have to forget about it and move on to the next game right away."
The Islanders are back in action on Thursday night, as they host the New York Rangers at Barclays Center. Puck drop is at 7 p.m.
