Annunen stopped 25 of 26 shots in Sunday's 4-1 win over the Sharks.
Annunen made his first start of the season after appearing in relief in the first two games of the year. The 24-year-old had little trouble with the Sharks, allowing just a William Eklund power-play goal in the first period. Annunen has given up five goals on 43 shots over his three appearances, going 1-1-0. The Avalanche's slow start is well-documented, but each of Annunen and Alexandar Georgiev have won their most recent outing. The Avalanche visit the Kraken on Tuesday.
