Lundestrom and the Ducks avoided arbitration with the deal announced Monday. Anaheim general manager Pat Verbeek has re-signed all of the club's restricted free agents.
The 22-year-old Lundestrom had 16 goals and 19 assists last year in his first full NHL season, ranking fourth on the roster in goals. The Swede also excelled as a penalty killer, tying former Ducks forward Corey Perry's franchise record with four short-handed goals.
The Ducks' first-round pick in 2018 has 22 goals and 22 assists in 151 career games. After the retirement of longtime captain Ryan Getzlaf, Lundestrom is likely to be Anaheim's third-line center next season behind Trevor Zegras and new free agent signee Ryan Strome, who signed a five-year deal in Anaheim after leaving the New York Rangers.
