Annunen played great in his only start of the season with the Avalanche, stopping 19 of 20 shots (.950 SV%) for his first win of the season against St. Louis. With Colorado not playing until Friday, he has been reassigned to the Colorado Eagles (AHL) for the time being.

Annunen has a 16-8-4 record, .912 SV% and 2.55 GAA with the Colorado Eagles (AHL) and has been recalled for the first time this season Friday. Annunen is expected to start one of the Avalanche's back-to-back games this upcoming weekend.

Colorado picked Annunen in the third round of the 2018 draft and is viewed as the potential future in net for them. The 20-year-old netminder was spectacular in the Finnish Elite League in 2019-20, going 15-5-3 while leading the league in both GAA (1.77) and SV% (.920). He also represented Finland at the World Juniors in 2020, where he finished the tournament with a 2.65 GAA and .916 SV% in six starts.
