Mittelstadt scored a goal on three shots and added a power-play assist in Saturday's 6-4 win over the Sharks.
Mittelstadt opened the scoring with his 100th career NHL goal, then assisted on Fraser Minten's third-period power-play winner. The veteran center has four goals this season and continues to provide useful secondary scoring for Boston, but regular scoring opportunities might be limited as long as he continues to operate in a middle-six role.
