He made an unbeaten 204, supposedly at the age of 15 years and 215 days, playing for Karachi Whites against Bahawalpur in the national championship, which would break the 13-year record of another Pakistani, Ijaz Ahmed.
But doubts about his exact age have been present ever since he played in the Under-15 World Cup in England two years ago. Ten other boys originally selected for that squad were found to be over-age although Hasan was cleared. Six of the Pakistan Under-19 party to the West Indies the same year were found to be too old.
After his debut against Zimbabwe in the second Test at Faisalabad - he scored 27 in his only innings - the Pakistan Cricket Board said medical tests showed him to be "about 15".
Majid Khan, the Pakistan Cricket Board chief executive, has said they do not accept Hasan's age.Reuse content
