Minnesota beats Toronto in Game 5, advances to inaugural PWHL championship

Minnesota defeats Toronto 4-1 to win their best-of-five semifinal playoff series 3-2. Minnesota will face Boston in the PWHL's inaugural Walter Cup final.

Toronto was minus veteran star forward Natalie Spooner, who led the league in both goals and points in the regular season, after she suffered a season-ending knee injury in Game 3.

Boston swept Montreal 3-0 in the other semifinal.

Heise heats up

The top pick in September's first-ever PWHL draft — which was held in Toronto — Heise snapped the winner past Campbell's glove on a power play at 8:30 of the third after Canadian national team defender Jocelyne Larocque was penalized for hooking.

Toronto tried to press as the clock ticked down, but never really threatened Rooney, who replaced Nicole Hensley after Game 1, minus its offensive dynamo before Kunin iced it into the empty net with 1:12 left.

Heise added her second into the open cage with 14.6 seconds remaining.

Playing in a city used to playoff hockey heartache, Toronto opened the series with 4-0 and 2-0 victories on home ice before Minnesota returned the favour with a 2-0 triumph and that extra-time decision.

The visitors went ahead on their first power play at 7:29 of the second when Kelly Pannek's initial shot beat Campbell five-hole and hit the post before the puck bounced in front for Krizova to bury her second of the series.

Without a goal since late in Game 2, Toronto finally broke through on Rooney just 38 seconds later when Leslie took a pass from Victoria Bach and fired her first to send a packed Coca-Cola Coliseum — home of the American Hockey League's Marlies on the Exhibition Place grounds — into a towel-waving frenzy.

Minnesota head coach Ken Klee suited up for more than 900 NHL games with seven teams, including parts of two seasons with the Maple Leafs. The former defenceman played a winner-take-all Game 7 in Toronto some 20 years ago when the Leafs topped the Ottawa Senators 4-1.
