Marchessault recorded two assists, six shots on goal and two PIM in Thursday's 4-3 loss to the Stars.
Of the Predators' three big free-agent signings, Marchessault had the most successful team debut. He set up a power-play goal by Filip Forsberg in the second period and also found Ryan O'Reilly for an extra-attacker tally in the third. Marchessault produced 42 goals and 69 points over 82 regular-season games with Vegas last year, his third season above the 60-point mark. The 33-year-old winger is a lock for top-six minutes and time on the first power-play unit in his first year with Nashville, and he should be a productive option for goals, shots and hits in particular.
