PARIS - The winner of a competitive renewal of the five-furlong Prix de l'Abbaye de Longchamp on Sunday will automatically qualify for a spot in the Breeders' Cup Turf Sprint, but a more important race on the Arc undercard, the Prix de l'Opera, may reveal more about possible Breeders' Cup runners at Santa Anita on Nov. 6 and 7.
At 1 1/4 miles, the Group 1, $373,000 Opera is an ideal prep for the Filly and Mare Turf. A half-dozen first-class fillies and mares are included in the 12-runner field, and any one of them could prevail without raising an eyebrow.
