South Korea’s Casey Phair becomes youngest player in women's World Cup history at 16 years old

Casey Yu-jin Phair made World Cup history Tuesday in Sydney, Australia.

Phair entered South Korea’s 2-0 loss to Colombia in the 77th minute in the country’s first game at the World Cup this month. At 16 years old, that officially made Phair the youngest to ever take the pitch at a women’s World Cup.

The previous record belonged to Nigeria’s Ifeanyi Chiejine. She was 16 years and 34 days old when she made her debut in 1999. Phair beat that mark by just eight days.

Phair was born in Korea but grew up in the United States. Her mom in Korean, and her dad is American. They moved to the U.S. when she was just a month old, and she started playing soccer just a few years later. They settled in New Jersey, where she scored 25 goals in 15 games last fall as a freshman at the Pingry School. Phair has trained with both the United States women's national team camp and South Korea's, though the latter quickly won out.

Phair scored five goals in just two games with South Korea’s U-17 team in Asian Cup qualifying earlier this spring. It wasn’t long after that that she was drafted up to the senior team, and eventually she made the World Cup roster — which made her the first mixed-heritage player to do so in the team’s history. Much of Phair's family still lives in South Korea, and her dad, Shane, estimates that they spend about half of their time in the country.

Colombia took a 2-0 lead before halftime Tuesday and ran away with the match. Catalina Usme scored first in the 30th minute on a penalty kick, and then Linda Caicedo scored again less than 10 minutes later. They held on the rest of the way and shut South Korea out to take the 2-0 win.

South Korea will take on Morocco next on Saturday before playing a final game in Group H against Germany next week.
