the 23rd and 24th February 1988. In my mind, and having read quite a lot about it, it is one of the most dramatic stories in history.
Three-day match played between schoolboys is an interesting background, particularly for us in England where two-day or three-day cricket is limited to very high level schools cricket and county youth teams. Sharadashram lose two early wickets, before Tendulkar and Kambli, on what cannot have been a perfect batting strip, embark on the most epic partnership in cricket history.
Consider 13-year-old Amol Muzumdar, who would later set the record for the highest score on first-class debut, padded up and waiting for a wicket to fall.
Consider Sairaj Bahutule, who would later play for India in the Kolkata Test in 2001, getting ripped apart despite having the potential to one day be the second best legspinner in India.
Consider the 14-year-old Tendulkar being told to declare by his coach at the close of play on the first day, yet being headstrong enough to keep batting with Kambli the next day.
Consider a 14-year-old, playing in probably the most competitive schoolboy competition in the world, averaging over a thousand runs in a single tournament.
And that, my friends, would be worth seeing.
