 Rock Sand started quickly and took an early advantage before the Royal colt Mead took over and led until just before the turn into the straight, where Maher moved Rock Sand back into the lead.The French-trained second favourite Vinicius came from well back in the field to emerge as the main challenger in the last quarter-mile but could never catch Rock Sand who won by two lengths, with Flotsam two lengths further back in third.It was the first of three Derby winners for Maher and the third successive win for an American jockey following the wins of Lester Reiff in 1901 and Skeets Martin in 1902.
