The Senators outhit the Maple Leafs 56-30 in Game 1 but many of their key young players including forwards Stutzle, Brady Tkachuk, Drake Batherson, Shane Pinto, Ridly Greig and Dylan Cozens, and defensemen Jake Sanderson, Thomas Chabot and Artem Zub each played their first Stanley Cup Playoff game.

Greig’s second-period hit struck Tavares in the neck area as the Leafs forward finished a check. Officials initially assessed a five-minute major, which was downgraded to a two-minute minor after video review, prompting Berube's gesture.
