Not much between French Oaks fillies

There is little to choose from between Coquerelle and Vadapolina in Group 1, $1.08 million Prix de Diane, the 1 5/16-mile French Oaks, which will have its 159th running at Chantilly on Sunday.

Trained by Jean-Claude Rouget, Coquerelle remained undefeated in four starts when she took the Diane's key prep, the 1 1/4-mile Group 1 Prix Saint-Alary at Longchamp May 20. The Zamindar filly will again have Christophe Lemaire in the sadddle.

In Vadapolina she meets a Trempolino half-sister to 2005 Saint-Alary winner Vadawina. Trained by Andre Fabre for the Aga Khan, Vadapolina is coming off a sharp score in the 1 5/16-mile Group 3 Prix Cleopatre at Saint-Cloud on May 1 and will retain the services of Christophe Soumillon.

The Aga Khan won this race four times in the 90s. Vadapolina is a progressive sort who can add a fifth French Oaks title to his resume.

Pressuring those two could be the half-length Saint-Alary runner-up Believe Me, an In the Wings filly trained by last week's French Derby winner, Jean-Marie Beguigne, as well as Mrs Lindsay, a Kentucky-bred daugher of Theatrical who has been freshened since winning the 1 5/16-mile Group 3 Prix Penelope at Saint-Cloud April 9. Another Fabre entry, Cinnamon Bay, looks dangerous off a recent three-length listed race win.

The lone British challenger is Sweet Lily, a Michael Channon trainee who was a neck second to English Oaks flop Passage of Time in the Group 3 Musidora Stakes last month.
