 Rock Sand's earnings of £22,633 in 1903 enabled his sire Sainfoin to his best position of second on the list of leading sires.On his four-year-old debut, Rock Sand ran against Sceptre again in June over the Derby course and distance in the Coronation Cup, a race which also featured the first meeting between Rock Sand and his contemporary Zinfandel, a colt whose engagements in the previous year's classics had been rendered void by the death of his owner Colonel Harry McCalmont.Zinfandel won easily from Sceptre, with Rock Sand third.
