BOSTON (Interstat) — Aerin Frankel made 21 saves and Boston Fleet beat Vancouver Goldeneyes 2-0 at Agganis Arena in a Professional Women’s Hockey League game. Boston remained unbeaten and handed Vancouver its third loss of the young season. Boston led after one period and protected the lead behind Frankel, who earned the win after stopping every shot she faced.

Boston opened the scoring at 5:02 of the first period when Abby Newhook scored, with Hadley Hartmetz and Theresa Schafzahl assisting. Vancouver’s Hannah Miller was called for holding at 9:01 of the first, and Brooke McQuigge received a tripping penalty at 18:28. The Goldeneyes killed both penalties but could not generate enough offense against Frankel. Jill Saulnier gave Boston breathing room with a goal at 6:40 of the third period. Vancouver pressed for a comeback, but Frankel and the Fleet defense held firm.

Frankel, a 5-foot-5 goaltender from Chappaqua, N.Y., finished with 21 saves on 21 shots. Saulnier, a 5-foot-5 left wing, had one goal and five shots. Newhook, a right wing, also scored one goal and recorded five shots. Hartmetz, a 5-foot-5 defender, added one assist and two shots. Ella Huber, a 5-foot-5 right wing, contributed five shots and two hits. Alina Müller, a 5-foot-5 center, had two shots and one hit. Schafzahl, a 5-foot-8 left wing, recorded one assist. Liz Schepers, a 5-foot-7 center, delivered two hits. Daniela Pejšová, a 5-foot-8 defender, had two shots and one hit. Hannah Brandt, a 5-foot-6 center, finished with one shot.

Boston improved to 3-0. The Fleet previously defeated Montreal 2-0 at home and Toronto 3-1 on the road. Vancouver dropped to 1-3. The Goldeneyes beat Seattle 4-3 in overtime earlier in the season but have since lost to Ottawa and New York. Boston’s victory continued a strong start that has featured timely scoring and solid goaltending. Vancouver, meanwhile, remained in search of consistency on the road. It was Boston’s second shutout of the season. Vancouver has lost three consecutive road games.

The Goldeneyes will return home to face New York Sirens, then host Ottawa Charge, Montreal Victoire and Minnesota Frost. The game against Minnesota is scheduled for Edmonton, Alberta. Vancouver also has road games at New York, Boston, Ottawa, Montreal and Toronto, plus a home matchup with Toronto. Boston will host Minnesota Frost before road games at New York, Minnesota, Seattle and Ottawa. The Fleet later meet Vancouver in Detroit, then host Seattle, Ottawa and Toronto before traveling to Seattle. The teams are scheduled to meet again when Vancouver visits Boston in Detroit.

Vancouver’s penalty kill was tested twice in the first period. Miller’s holding call came after Boston had taken the lead, and McQuigge’s tripping penalty gave the Fleet another power-play chance before the intermission. Boston did not convert on those opportunities, but the Fleet’s defensive structure limited Vancouver’s chances. Newhook’s opening goal stood as the winner until Saulnier scored in the third. Frankel’s clean sheet was the central story, as she turned aside 21 shots and anchored Boston’s third win in as many games. Vancouver’s penalty kill kept the deficit at one goal until the third.

The win kept Boston atop the early PWHL standings. Vancouver, which has played four games, remained at one victory. Boston’s offense spread the puck around, with Newhook, Saulnier, Hartmetz and Schafzahl all contributing points. The Fleet also received physical play from Huber, Schepers and Pejšová. Vancouver’s best chances came in the second and third periods, but Frankel was steady in net. Boston’s defense blocked shots and cleared rebounds, helping preserve the shutout. The Goldeneyes pulled their goaltender late but could not score.

Interstat’s ELO system had projected Boston with a 53.9 percent probability to win.
