Colgate University (2015–2019) Eldridge played four seasons (2015–2019) for the
Colgate Raiders, finishing her collegiate career as the program's all-time leading scorer in
NCAA Division I competition with 74 goals and 89 assists for 163 points in 153 games. She then scored the game-winning goal against
Cornell in the ECAC semifinal with one second remaining, sending the Raiders to their first ECAC Hockey Championship game. Eldridge was named ECAC Hockey Player of the Month for February 2018 and Hockey Commissioners Association (HCA) National Player of the Month for the same period. She earned All-ECAC Hockey All-Conference Second Team honors and won her second consecutive Colgate Women's Hockey Offensive MVP award. In the championship game, Colgate fell 2–1 in overtime to top-seeded
Clarkson. As team captain in her senior year, Eldridge set program records with 30 goals and 54 points in 38 games. She scored twice in that game, bringing her career point total to 143. Eldridge appeared in the
2018 NCAA National Collegiate Women's Ice Hockey Tournament Championship game, an historic first in program history. In the
2018–19 Colgate Raiders women's ice hockey season, her 30-goal output broke the program record for most goals in a single season.
PWHPA (2019–2023) Eldridge joined the
Professional Women's Hockey Players Association (PWHPA), formed in May 2019 after the dissolution of the
Canadian Women's Hockey League. The PWHPA was established by over 200 players who boycotted existing professional leagues in pursuit of a unified, financially sustainable professional league that would provide salaries, health insurance, and proper infrastructure. Skating for Team Bauer (Montreal), Eldridge participated in the 2021 Secret Cup, the Canadian leg of the PWHPA Dream Gap Tour held in Calgary. On May 28, 2021, she recorded a goal and an assist in a 4–3 victory over Team Scotiabank (Calgary). Nine of her 12 points were primary points, and five of her goals came at even strength. In the Secret Cup championship final on March 12, 2023, at
Acrisure Arena in Palm Desert, California, Eldridge scored the game-winning goal with 42 seconds remaining in regulation to give Team Harvey's a dramatic 5–4 victory over Team Scotiabank. She finished the championship game with a goal and three assists for four points. She signed a two-year contract with the club in November 2023. In December, following a preseason that saw her lead the league with six points in three games, Eldridge's contract was upgraded to three years. In the
2023–24 season, Eldridge played all 24 games for New York, recording seven goals and seven assists for 14 points. New York finished in sixth place with a 6–15–3 record and failed to make the playoffs, but earned the first overall pick in the
2024 PWHL Draft. In the
2024–25 season, rebranded as the
New York Sirens, Eldridge played all 30 games and improved her offensive production with nine goals and 15 assists for 24 points, finishing as one of the league's top point producers. On November 28, 2025, Eldridge played in Seattle's historic home opener at
Climate Pledge Arena, where 16,014 fans set a new U.S. attendance record for a professional women's hockey game, surpassing the previous mark of 14,288 set in Detroit. The attendance also established the highest-attended primary home venue game in PWHL history, though Seattle fell 3–0 to the two-time defending
Walter Cup champion
Minnesota Frost. Her goal came with 26 seconds remaining in the third period, spoiling goaltender
Abbey Levy's shutout bid. On January 11, 2026, Eldridge scored an unassisted goal late in the second period of a game against the
Minnesota Frost which cut the Torrent's deficit to 3–1 and ending its scoreless stretch of nine games despite losing the away game 6-2. On January 20, 2026, she recorded three points with a goal and two assists in Seattle's 6–4 victory over Toronto, in the highest-scoring game of the PWHL season. The Torrent's six goals set a franchise record and matched the season high for any PWHL team. Eldridge was named the first star of the game. On January 25, 2026, Eldridge scored the Torrent's lone goal in a 3-1 loss to Vancouver in Denver as part of the
PWHL Takeover Tour. Three days later, in the final game before the league's
Olympic break, Eldridge recorded her third multi-point performance for the Torrent against the
Ottawa Charge at
TD Place and assisted on
Hilary Knight's 50th career PWHL point in the second period. In the third period, she scored a top-shelf wrist shot to give Seattle a 2–1 lead and extended her goal-scoring streak to three consecutive games. The Torrent ultimately fell 4–2 after Ottawa scored three goals in the final six minutes. The game marked the end of a stretch in which Eldridge accumulated eight points in five games after recording only two points in her first nine appearances with limited minutes. Despite this, she finished the first half of the season tied for second on the Torrent in both points and goals with 10 points (5G, 5A) in 16 games.
Boston Fleet (2026–present) On March 16, 2026, Eldridge was traded to the
Boston Fleet in exchange for forward
Theresa Schafzahl.
The Athletic indicated that Eldridge had not been likely to re-sign with the Torrent and the trade looked like a "significant offensive upgrade for Boston". == International play ==
