"Of course I didn't expect this before the game," Johnsson said. "Obviously, nice to score. After (the third goal) the feeling kind of felt unreal. It's kind of hard to explain.

Patrick Marleau, Josh Leivo and John Tavares scored, and Mitchell Marner had two assists for Toronto (16-8-0), which had lost two in a row, including 4-2 at the Columbus Blue Jackets on Friday, after a four-game winning streak.

"They always say don't read what's written about you; I can't not read it, so just hopefully settle in, play hockey, and do what I do best: stop pucks."
