Treve unleashed an explosive acceleration in the straight and won the Prix de Diane Longines (Fr-I), or French Oaks, in her stakes debut June 16 at Chantilly.
Haras du Quesnay's Motivator filly, lightly regarded at 9-1 odds, raced near the back of the field early and rapidly advanced to take the lead from Sage Melody 300 meters out. She drove clear to a four-length victory from maiden Chicquita (16-1), who rallied from last, with two-time group I winner Silasol (7-2) a short neck back in third.
Bidding for a second classic success after winning the Poule d'Essai des Pouliches (Fr-I), or French One Thousand Guineas, last month, 2-1 favorite Flotilla was never a factor and finished eighth in the 11-horse field.
Treve won for the third time in as many career starts for trainer Criquette Head-Maarek, who enjoyed a third triumph in the classic following previous wins by Egyptband in 2000 and Harbour in 1982.
Ridden by Thierry Jarnet, Treve was timed in 2:03.77 for 2,100 meters (about 1 5/16 miles) on turf rated as good.
A winner going a mile in her only outing as juvenile last September at Longchamp, Treve scored by 3 1/2 lengths going the same distance May 15 at Saint-Cloud in her season debut. She stepped up to handily defeat much more accomplished rivals in the French Oaks.
A Head family homebred, Treve is out of the winning Anabaa mare Trevise, a full sister to United States stakes winner Tsigane, who was grade I-placed. Her second dam, Trevillari, is a full sister to French group I winner Treble. Fourth dam Trillion was champion in the United States and Europe. A half sister to French group II-placed Trois Rois, Treve failed to meet her reserve at the 2011 Arqana October yearling sale on a final bid of €22,000.
