Filly can beat boys at Chantilly

The filly Impressionnante may just be good enough to give her 11 male rivals a beating in a highly competitive renewal of the $511,000 Prix Jean Prat, Sunday's Group 1 mile for 3-year-olds at Chantilly.

The Carlos Laffon-Parias-trained Impressionnante was a course and distance winner at the Group 2 level when she won the Prix de Sandringham against her own age and sex on June 4. Out of Occupandiste, a two-time Group 1 winner herself against colts, Impressionnante had previously been an unlucky third in the French 1000 Guineas in which she was placed second via the disqualification of Price Tag. Olivier Peslier takes the ride in the blue and white colors of the Wertheimer brothers.

Stormy River, third in the French 2000 Guineas and second in the St. James's Palace Stakes for Nicolas Clement, is the likely favorite, but equally dangerous are Kentucky Dynamite, an improving Kingmambo colt who took the one-mile Group 3 Prix de la Jonchere at Chantilly on June 11; Boris de Deauville, a Soviet Star colt who won his maiden last time in the 1 1/8-mile Group 3 Prix de Guiche; and the Aidan O'Brien-trained Ivan Denisovich, who showed signs of life when finishing third in the St. James's Palace at Royal Ascot three weeks ago.

Most intriguing of all is the Aga Khan's Dilek. By St. James's Palace and Prix du Moulin winner Sendawar, Dilek is coming off a two-length June 26 score in the Group 3 Prix Daphnis. To be ridden by Christophe Soumillon, Dilek has been supplemented to the Jean Prat for $30,000 off four straight victories, all of which, however, have come between 1 1/8 and 1 5/16 miles.
