A teammate of former Isles d-man Nick Leddy in St. Louis, Scott Perunovich hopes to elevate his game with his new team.

A year ago, it was a Nov. 24 match in Ottawa that immutably changed the season for the Islanders, when Adam Pelech and Sebastian Aho both got hurt, trimming the Isles down to four defenseman for an eventual win over the Senators.

Perunovich was acquired from the St. Louis Blues on Monday afternoon, helping to fill the void left by Ryan Pulock’s upper-body injury. It was a whirlwind 24 hours for the 26-year-old, who is expected to make his Islanders debut against Colorado.
