Dahlin notched two assists, one on the power play, in Tuesday's 5-1 win over the Senators.
It's the second multi-point performance in the last five games for Dahlin. After a bit of a quiet start to the season, the 24-year-old blueliner has gotten rolling with a goal and nine points over the last 10 contests, adding 31 shots on net, 16 blocked shots and a plus-7 rating during that stretch.
