A filly by leading Japanese sire Sunday Silence brought $575,000 (approximately $307,050 in U.S. funds) to top the second session of the Australian Easter yearling sale on Wednesday. Planette Thoroughbreds purchased the racy-looking brown filly from Arrowfield Stud. She was produced from the 7-year-old Avenue of Flags mare Laurel Avenue, winner of the 1997 Washington Thoroughbred Breeders' Association Lassie Stakes at Emerald Downs.The top-priced colt was a $550,000 ($293,700) son of Zabeel that was produced from 1992 Australian Horse of the Year Let's Elope (by Nassipour). He is a half-brother to Australian group II winner Ustinov (by Seeking the Gold). The colt was purchased by bloodstock agent John Foote from Vinery Australia, agent for Dennis and Margaret Marks. The Markses raced and still own Let's Elope.Through two sessions, 241 yearlings have been sold for a gross of $37,622,500 ($20,090,415) and an average of $156,109 ($83,362)."Tonight 's session probably lacked a real standout, but in saying that, our average has held up remarkably well from yesterday," said Reg Inglis, managing director of William Inglis & Son.The sale's final session is Thursday.
