I was fortunate enough to see many great innings in my time in Grade cricket. However the one that stands out as far as courage is concerned was played by a Gordon batsman who played very little First Grade and, indeed, not nearly enough Grade cricket.
John Shattock had played for Gordon for a couple of years, starting in the lower grades. A workman-like opening batsman, in 1970-71 he set 5th Grade Aggregate record (which still stands!). He moved up the grades and in 1972, he was chosen to play his first 1st Grade game (my first game in the top grade as well). It was a quiet introduction with John scoring a handful not out against Mosman with the second day being completely washed out.
