South Korea forward Casey Phair on Tuesday became the youngest ever player to appear at the World Cup – just 26 days after celebrating her 16th birthday.

The US-born teenager came on as a 78th minute substitute in South Korea’s 2-0 loss to Colombia in Sydney, beating the record of Nigeria’s Ifeanyi Chiejine, who was 16 years and 34 days old at the 1999 Women’s World Cup.
