First-season sire Kheleyf has enjoyed a truly outstanding month and on Saturday Lady Master became his twelfth winner since the start of July and his 19th winner overall when she was successful at Lingfield.
The Henry Candy-trained filly made virtually all in the five furlong contest and held on to cross the line a neck ahead of Ruby Tallulah, with You've Been Moved the same distance back in third.
Bred by Diana Du Feu, Lady Master is the first foal out of Sysygy, herself a daughter of four-time winner and Falmouth and Pretty Polly third Theano.
Kheleyf is also sire of G3 winner Percolator, who finished second in today's G2 Prix Robert Papin, and Stakes-placed duo Sayif and Touching.
On the same day as Lady Master's win, fellow first-season sire Sulamani recorded his second winner when his daughter Sulabe took the Premio Amalfi, run over just under seven furlongs at Tagliacozzo in Italy.
