Campbell made 26 saves to improve to 9-0-0, tying him for the longest winning streak by a goalie in Toronto history with Felix Potvin (Oct. 7-28, 1993), Jacques Plante (Dec. 12, 1970-Jan. 9, 1971) and John Ross Roach (Jan. 31-Feb. 28, 1925).
"You don't get those wins without everybody," Campbell said. "Tonight, we got a huge contribution from the power play and kind of put the game away. We've just been building our game all year. It's really coming full circle here. I'm liking the boys' effort and we're just trying to get better every night. The record's a huge honor to be tied or whatnot, but it's just all about winning."
Mikael Backlund scored two goals for Calgary (16-21-3), which has lost four straight and is 2-9-0 since a three-game winning streak that started when Darryl Sutter took over as coach March 11. Jacob Markstrom made 25 saves.
"We're not scoring and we're not giving up a whole lot, but when we do, it feels like it's in the net," Backlund said. "We're just giving up too big of chances when we do give chances. I feel like there's a lot of close games. We do keep it tight but just didn't score enough. When we give up chances, they're usually big ones and they're usually in the net. It's just a bad cycle. It has been for a while. We have to stop it."
Matthews scored his NHL-leading 27th goal on a scramble in front on the power play to put the Maple Leafs ahead 4-3 at 10:50 of the third period. Tavares had an assist to reach the milestone.
"It wasn't a pretty one by any means, but it was a nice one to get our power play back on track and obviously a big goal in the game," Matthews said.
