Theresa Schafzahl scored with 52 seconds left to lift Boston a thrilling 3-2 win over host Ottawa during a Professional Women’s Hockey League clash before 5,208 fans at TD Place.

Boston (3-2) took a 2-0 lead in the first period thanks to goals from Alina Muller and Jamie Lee Rattray. Megan Keller set up Muller’s goal, while Sophie Shirley and Sidney Morin assisted on Rattray’s tally.

But Ottawa rallied to tie the game on a second-period goal and then one in the third period to set the stage for Schafzahl’s heroics.

Former Northeastern University star goaltender Aerin Frankel stood tall in net, stopping 37 of 39 shots. Boston is now 3-0 on the road.
