Ottawa is headed to the PWHL Finals for the first time in their franchise's history after a 2-1 victory over Montreal to win their semifinal series 3-1.

Clark scored 31 seconds into the third to give Ottawa a 2-0 lead. Clark made a great move to get around Marie-Philip Poulin and drove to the net where she sent a shot to the top corner.

Montreal challenged the goal, saying there was a hand pass on the play, but the goal stood and the Victoire were assessed a penalty for the failed challenge.

Montreal cut the lead in half with 5:02 remaining in regulation when Murphy drove to the net beat Gwyneth Philips shortside. Philips was solid for the Charge, making 19 saves.

Ann-Renee Desbiens made 20 saves, but for the second straight year the Victoire were eliminated by their opponent of choice.

Both teams had power-play chances in the second but were unable to capitalize.

Midway through the period, Tereza Vanisova broke in alone but Desbiens was there to make the initial save, as well as a Brianne Jenner chance.

The Victoire generated three shots on its power play. Philips stopped both Poulin and Stacey,

The Charge got off to a solid start and were rewarded early with Ottawa native Leslie scoring at the two-minute mark of the first period.

Leslie put away her first goal of the playoffs on an Anna Meixner rebound.
