An unstoppable power play, edge in goal and contributions from unlikely sources have the Maple Leafs on the verge of the second round.

The Senators got on the board first with a Claude Giroux goal on the power play in the second period. Matthew Knies knotted the score at 1-1 with a goal before the second intermission. Matthews put Toronto ahead for the first time early in the third period before Brady Tkachuk leveled it all up at 2-2 with an even-strength goal.
