Brayden Schenn and Oskar Sundqvist scored, and Binnington made 27 saves for the Blues (7-9-0), have lost three in a row and ended a season-long five-game homestand 2-3-0. St. Louis was 5-0-0 when leading after two periods.

After the first two periods Tuesday night in St. Louis, it looked like the Boston Bruins were about to suffer another bad loss in a season full of them. They trailed the Blues 2-0 through two periods.

David Pastrnak is in a goal scoring slump, and until he breaks out of that, the Bruins offense as a whole is in trouble.
