Back to back: Frost beat Charge in overtime to successfully defend Walter Cup crown

The Minnesota Frost are PWHL champions once again.

Liz Schepers scored at 12:00 in overtime of Game 4 to give Minnesota a decisive 2-1 win over the Ottawa Charge on Monday, and a second Walter Cup in as many years.

The Ilana Kloss Playoff MVP award was given to Charge goaltender Gwyneth Philips.

Each game in the best-of-five series went to at least one overtime and finished 2-1, with Game 3 going to triple overtime, the longest game in PWHL Finals history.

The teams played 81 minutes, eight seconds of extra time in the series. The fourth game came exactly a year after Minnesota fell to Boston 1-0 in a Game 4 double overtime before going on the road to win the inaugural Walter Cup.

Katy Knoll went along the wall and fed Schepers in front of the net. Goaltender Gwyneth Philips parried the first shot but Schepers poked home the rebound to clinch back-to-back Walter Cup titles for the Frost.

Maddie Rooney had 33 saves for Minnesota.

The goal marked the first time in the finals the Charge trailed in regulation.

The Charge trailed until the middle of the third period when Tereza Vanisova was left alone in front of the net and Danielle Serdachny fed her from below the end line.

It was the first point of the post-season for Vanisova, who led Ottawa with 15 goals.

Philips had 36 saves. The rookie had 148 saves in overtime in the postseason.

Ottawa's Aneta Tejralova, on a rush, hit the left post with a shot about five minutes into overtime and the Frost's Taylor Heise hit the right post about four minutes later.
