KK Ream

Club career

Ream began training with the Utah Royals professional team in the 2024 preseason. After a preseason friendly in which Ream scored three goals against BYU, her teammate Kate Del Fava said in an interview: "Three syllables ... KK Ream".

Ream made her professional debut as a late substitute against the San Diego Wave on March 23, 2025. She became the youngest starter in NWSL history on May 3, in a 2–0 loss to the North Carolina Courage. On August 29, she scored her first professional goal, the decisive tally in a 2–1 win over the Portland Thorns. At 16 years and 52 days old, she became the youngest-ever NWSL goalscorer, beating the record set by Alex Pfeiffer the year prior. On March 26, 2026, it was announced that Ream had been placed on the season-ending injury list after having sustained an ACL tear during training.

International career

Ream helped the United States win the 2024 CONCACAF Girls' U-15 Championship, converting a penalty kick in the semifinal shootout against Canada. The following year, she was named to the roster for the 2025 FIFA U-17 Women's World Cup.
