The Maple Leafs went up 2-0 at 3:08 of the second period when Matthews sent a lead pass through two defensemen to Nylander, who scored on a breakaway.
"They've got some good speed under their feet and can score goals, so we've got to do a better job eliminating that," Lightning defenseman Victor Hedman said. "Other than that, I thought we controlled the pace of the game. We created a lot of chances and it could have gone either way, but obviously, those guys are two top guys in the League, so next time we play them, we have to make sure we shut them down a little bit better."
Gardiner extended the lead to 3-0 at 11:36 when he took a pass from Nylander and shot from the high slot, using Lightning defenseman Andrej Sustr as a screen.
