This Derby Final was remarkable for the fact that the winner was such a popular dog – known as "Cindy" to her owners, the White brothers, and her supporters and because Dolores Rocket became the first bitch for fully 41 years to win the Derby. Supreme Fun in 6 was expected to lead early and he duly did from Leap and Run (3), Ivy Hall Flash (4, and Fav.), Cobbler (5), Moordyke Champion (1) and Dolores Rocket (2), in a seemingly hopeless position bringing up the rear. Going into the bend Supreme Fun moved off wide allowing Leap and Run to take over while Cobbler and Ivy Hall Flash crowded badly, ruining their chances and allowing Moordyke Champion and Dolores Rocket room to gain on the leaders as they ran up the back straight. The third bend saw Supreme Fun and Leap and Run neck and neck in the lead. Here the race was won. Rounding the last bend with a brilliant piece of trackcraft .Dolores Rocket left her accustomed rails pitch and came round her field in game style to out-run Supreme Fun by half a length and land the £10,000 first prize in 28.74 secs. – an excellent time. "Cindy", the "black bundle of energy", who had deprived Sole Aim of a final spot by a short head in their semi-final, thus emulated the great Narrogar Ann, winner in 1949. Dolores Rocket would further cement her place in history by going on to win the St Leger later in the year.
