Marchessault scored a goal on two shots, added an assist, went plus-3 and logged six hits in Wednesday's 3-1 win over the Stars in Game 2.
Marchessault provided a quick response to Jason Robertson's opening goal late in the first period. In the third, Marchessault set up Jack Eichel's empty-netter.
