[4] Minstrella's dam Flight Dancer won four times as a juvenile in 1970 and was a half-sister to the Jockey Club Stakes winner Dancing Moss.
[8] She took the lead a furlong out but began to swish her tail under pressure and was beaten three quarters of a length by Forest Flower: Timeform noted that she was a filly who "had her foibles".
Reid sent Minstrella into the lead in the last quarter mile and held off a strong challenge from Forest Flower to win by a short head, with Polonia a length away in third and Wiganthorpe the best of the colts in fourth.
She started 11/10 favourite ahead of her rival, with the other three runners being Canadian Mill, Shaikiya (runner-up to Sizzling Melody in the Flying Childers Stakes) and Indian Lily.
Forest Flower seemed to be boxed in two furlongs from the finish, and her rider Tony Ives, in extricating the filly from her unfavourable position, bumped into Minstrella, who was clearly hampered.
[7] Minstrella's connections then took their case to the disciplinary committee of the Jockey Club, who overturned the original decision, ruling that Ives's manoeuvre had constituted intentional interference.
[7] Minstrella made her second-season debut in the 1000 Guineas over the Rowley Mile at Newmarket on 30 April for which she started at odds of 15/2 and finished sixth of the fourteen runners behind Miesque.
At Royal Ascot in June she was brought back in distance for the Cork and Orrery Stakes over six furlongs and finished fourth to the Irish colt Big Shuffle.
[11] In 1986, Minstrella was rated the best two-year-old filly to race in Ireland but was only fifth in the European International Classification behind Forest Flower, Miesque, Milligram and Sakura Reiko.
She was the dam of three Graded stakes races and the female-line ancestor of three others: Minstrella was euthanised in early 2012 at the age of twenty-eight and was buried at Spring Hill Farm.
