Zafuto played her college hockey at Colgate. Her junior and senior seasons, she ranked third-most nationally for points by a defenceman. She graduated with the most points (104) by a Colgate defenseman in program history.[1]
After a season-and-a-half, she returned to the United States to play in the rebrand of the NWHL, the Premier Hockey Federation (PHF), for the Boston Pride.[3] She was an All-Star selection for the 2022-23 season.[4] After one season with the Pride, Zafuto signed a 1-year $63,000 contract with the Metropolitan Riveters.[5] However, the PHF was acquired by the Mark Walter Group in 2023 and a new, unified league was set up: the PWHL.
Zafuto was drafted by New York in the twelfth round, sixty-ninth overall, in the inaugural PWHL draft. She signed a one-year contract and played in thirteen games for New York during the 2023–24 season, recording one assist.[6] She signed a reserve player contract with the Boston Fleet for the 2024–25 season.[7]
