Auston Matthews had a goal and an assist, and Pontus Holmberg had two assists for the Maple Leafs (21-13-8), who have lost four in a row (0-3-1). Jones made 28 saves.
Toronto held a 2-1 lead after the second period but gave up three goals in the third in a 4-2 loss to the Detroit Red Wings on Sunday.
“Obviously [we’re ticked] off about it, but all these games we’ve been playing, we’ve played some really good hockey,” Maple Leafs forward Mitchell Marner said. “We’ve just given them back. We’ve had a lot of chances to extend leads in games and haven’t done a good job of that.
“I thought we played pretty good defensively again tonight, but just a little slip up here and there. They’ve got a lot of skill that can make things happen.”
Matthews gave Toronto a 1-0 lead just 27 seconds into the first period with a shot from the edge of the left face-off circle after a cross-ice feed from Marner. It was Matthews’ NHL-leading 34th goal of the season.
“We did a lot of good things. We ran into a good team playing with a lot of confidence,” Matthews said. “It’s frustrating.
“Obviously we’d like to not be giving up these leads, but I think on the positive side, there’s a lot of good things that we are doing, and it’s just a matter of being consistent executing on some of these opportunities that we have later in games.”
