Dumoulin registered an assist, two shots on goal, two hits and four blocked shots in Friday's 5-4 overtime loss to the Avalanche.
Dumoulin has a helper in each of the last two games. The 33-year-old defenseman has played a shutdown role to begin his tenure with the Ducks, adding 12 blocked shots, eight hits, six shots on net and a plus-2 rating over four appearances. Dumoulin's playing style doesn't tend to lead to much offense, so he's unlikely to be anything more than a streaming option for non-scoring production in fantasy.
