The Lightning took a 1-0 lead at 13:16 of the first period when Maroon took a pass from Corey Perry on a 2-on-1 and shot from just below the left face-off dot. It was Maroon's first goal since March 27.
Tampa Bay killed off a two-minute 5-on-3 power play that began at 17:48 after Hedman took a minor penalty for hooking Marner before Mikhail Sergachev was called for a minor penalty for an illegal check to the head of Marner.
"He kind of came across and caught me up high a little bit," Marner said. "He apologized later in the second period there, but obviously it's something we really don't want happening in games, but it does happen still. Hopefully it gets out of the game, but it's a fast-paced game out there, stuff happens quickly."
Vasilevskiy made two saves in the second period on Wayne Simmonds: one at 9:16 when he stopped Simmonds alone in the slot after he took a pass from Nick Ritchie; the second at 19:28 on a breakaway with a right pad stretch.
"There's a lot of positives that come out of this, pulling two points out of it, the fact we found ourselves to push back in the second after, to me, our first period was, in terms of how the game flowed from shift to shift, I thought we just had nothing happening," Maple Leafs coach Sheldon Keefe said.
"I thought it was as poor a period we've played this season, so the fact we had to regroup ourselves and find another gear in our game, I liked that we did that. There's a lot of things we can take away from what we saw from the back-to-back champions tonight."
