Inserted into the lineup for Game 2 in absence of Erik Cernak, Zach Bogosian looked to give his team a spark when he dropped the gloves with Mark Giordano at the 3:02 mark of the first.
Shortly later, Matthew Knies was whistled for hooking and sent the Lightning to the power play 1:21 after the scrap between Bogosian and Giordano.
In a great opportunity to get the game tied up, the Bolts got a couple looks on their first power play of the night, but couldn't capitalize as Toronto continued to take hold of the momentum in the game and proceeded to jump out to a 2-0 lead with 7:15 left in the opening period.
After Anthony Cirelli got kicked out of the faceoff circle in the defensive zone, John Tavares won the draw for Toronto, found a soft spot near the hashmarks and fired a quick shot past Andrei Vasilevskiy to double the Leafs lead.
Only 2:23 later, Toronto had a 6-on-5 advantage with a delayed penalty set to be called on Tampa Bay before William Nylander got the puck at the left circle and wired a shot into the top right corner to send the Leafs to the first intermission with a 3-0 lead, the exact opposite situation they were in following the first period of Game One.
Over the first five minutes of the second period, Vasilevskiy stood tall in the crease and made some big saves to keep the score at 3-0. The Lightning were able to build off that and got back within two when Steven Stamkos skated into the Toronto end and sent a pass across the offensive zone to Ian Cole, who made a nifty move to the backhand and beat Ilya Samsonov to make it 3-1 with 11:02 left in the second period.
From there, the Bolts started to find their game and strung together multiple strong shifts as the momentum began to swing in their favor. But at the 13:14 mark of the middle frame, Tavares went unchecked in front of the net and buried a rebound off a shot from Morgan Rielly to make it 4-1 in what felt like the goal that really took the wind out of Tampa Bay's sails.
During some of the Lightning's losing efforts in regular season contests, there were times when the team would let things snowball and surrender multiple goals against in a short span of time. That was the case late in the second period on Thursday with Zach Aston-Reese scoring 2:38 after the Tavares goal and Marner making it a 6-1 game 2:10 later.
Heading to the locker room in a five-goal hole after 40 minutes, Bolts head coach Jon Cooper did say he considered giving Vasilevskiy the third period off, but the star goaltender wasn't having it.
"I did," said Cooper when asked if he considered pulling Vasilevskiy during the second intermission. "And that was quickly shut down by the goalie. And that's why he's the best in the world. He's not coming out.
"Once again, tip your hat to that kid."
