After graduating, she joined the PWHPA and spent the 2019–20 season with the organisation's New England hub.[7] She made her PWHPA debut at the Dunkin' Showcase in Hudson, New Hampshire in October 2019, winning the showcase with Team Stecklein.[8] She then played for Team Turnbull at the Philadelphia showcase in February 2020.[9] She remained with the PWHPA for the 2020–21 season, being named to the roster for the Calgary hub, dubbed Team Scotiabank. In the 2021–22 season, she joined the Toronto hub, Team Sonnet.
Naisten Liiga
In January 2022, Sauvé signed with the Naisten Liiga team HPK Naiset in Hämeenlinna, Finland, filling the vacancy created by the departure of Noora Räty to the Zhenskaya Hockey League.[10] She recorded the best save percentage and goals against average (GAA) of all goaltenders in the lower division series, a .964 SV% and 0.88 GAA, buoying the team to the top of the division and securing a playoff berth.[11] HPK lost the quarterfinals of the Aurora Borealis Cup playoffs in a four-game series against HIFK despite Sauvé's league-leading .955 SV% and highly competitive 2.29 GAA. Though she spent only a few months in Finland, Sauvé credited the time in the Naisten Liiga with reinvigorating her childhood love of ice hockey.[12]
PHF
Returning to North America after the half-season in Finland, Sauvé signed with the Buffalo Beauts as their starting goaltender for the 2022–23 PHF season.[13] Her official debut with the team was delayed until December 2022 after she sustained a hip injury in a pre-season exhibition match.[14] In her third game of the season, the injury was aggravated and she was placed on the injured reserve list.[15] In January 2023, she was moved to the long-term injured reserve (LTIR) list after it was determined that her hip required surgery; rehabilitation kept her from playing another game in the 2022–23 season.[16][17]
Despite effectively losing the previous season to injury, she remained a highly touted netminder and was signed for the 2023–24 PHF season by the Boston Pride in mid-June 2023.[18] The contract was on the books for less than two weeks before the PHF was sold and subsequently dissolved to make way for the Professional Women's Hockey League (PWHL) on 29 June 2023, voiding all PHF contracts.
PWHL
Sauvé was one of 44 goaltenders to declare themselves eligibile for the 2023 PWHL Draft, though she was not one of the ninety players who were drafted (only eight of whom were goalies).[19][20] Following the draft, she accepted an invitation to attend training camp with PWHL New York.[21][22] On November 30, 2023, PWHL New York cut her in the first round of roster reductions.[23]
Return to Europe
Shortly after being cut from PWHL New York, she signed with HPK Hämeenlinna in the Naisten Liiga for the remainder of the 2023–24 season.[24] She backstopped the team to a fourth place finish in the 2024 Aurora Borealis Cup playoffs and her .927 save percentage was third of all goaltenders playing four or more playoff games.
Sauvé signed a two-season contract in the SDHL with SDE Hockey in April 2024.[25]
