Sorokin allowed two goals on 34 shots in Monday's 6-2 win over the Avalanche.
The Isles conceded seven goals and went 0-1-1 in their first two games with Semyon Varlamov between the pipes, so this was a step in the right direction. The Islanders seem to be easing Sorokin back into action after he underwent back surgery in the offseason, and while he should eventually recover the starting role from Varlamov, it wouldn't be surprising if the latter starts against the Blues on Thursday in the final contest of New York's three-game road trip.
