Brayden Schenn's goal 7:23 into the game was the Blues' first score in a Cup final since 1970.

The Blues scored first for the 14th time in 20 playoff games and are 10-3 so far when doing so. They're also 6-1 when leading after the first period.

Discipline continues to be an issue for St. Louis, which took two penalties and put Boston's playoff-best power play to work. With goaltender Jordan Binnington not looking at all nervous, the Blues killed off each penalty and had one of the shots ring off the post.
