Lester Piggott
A month later, Petite Etoile started 11/2 second favourite for the Oaks, in which she was ridden by Lester Piggott. The favourite was the undefeated Cantelo, a filly whose wins included the Royal Lodge Stakes against colts and who was regarded as a superior stayer, whereas Petite Etoile's pedigree led to doubts about her stamina over one and a half miles. Petite Etoile was settled by Lester Piggott in the early stages before moving up into third place on the turn into the straight. She accelerated past Cantelo a furlong from the finish and won easily by three lengths. Later that year, Cantelo won the St. Leger Stakes.
