Casey Phair, welcome to the 2023 FIFA Women's World Cup.
Phair substituted into South Korea's Group H opener against Colombia on Monday and became the youngest ever player to feature in the prestigious tournament.
Born to a South Korean mother and American father, Phair set the record at 16 years, 26 days old. She was born in South Korea but moved to the United States when she was just one month old.
Her family resides in New Jersey, but her appearance in the World Cup means she is cap-tied to South Korea and can no longer switch national teams.
