Teenager Gilberto Mora became Mexico's youngest player in men's World Cup history after coming on as a substitute in the co-hosts' opening 2-0 win against South Africa.
The attacking midfielder was brought on in the 66th minute on Thursday at the age of 17 years and 240 days.
More than 80,000 fans inside Mexico City's Azteca celebrated the teenager with chants of "Mora, Mora." Immediately afterwards, Mexico increased their lead.
