Maroon logged an assist and six hits in Saturday's 5-1 win over the Maple Leafs in Game 1.
The helper was Maroon's first point in three outings as a Bruin. The 35-year-old, a three-time Stanley Cup champion, is set to occupy a fourth-line role this postseason as a hard-working veteran. He is also seeing time alongside David Pastrnak on the power play. Maroon had 16 points, 82 hits and 60 PIM over 51 regular-season appearances between Boston and Minnesota.
