Before the puck was dropped Monday, Senators owner Eugene Melnyk declared the sky is the limit for Erik Karlsson.

"He can only get better. Over time, he can go down in history with the great defencemen of all-time. He is that good," Melnyk told a Toronto radio station.

It sure looked that way in this matinee.

Led by Karlsson's two-goal, two-assist performance, along with Jason Spezza's two-goal effort, the Senators extended their winning streak to three games with a 6-0 rout of the New York Islanders.

While it was Family Day in Ontario, the Senators were promoting togetherness here as goalie Craig Anderson earned his third shutout of the season with 28 saves, while blueliners Chris Phillips and Brian Lee also scored.

But it was Karlsson who stole the show.
