The Ocala Breeders' Sales Company's spring auction of 2-year-olds in training established sale records for gross revenue and average price during its four-day run that ended April 26 in Florida. In addition, the auction's record for the highest-priced horse was equaled when a Grindstone filly sold for $550,000 on the final day. The mark first was established in 1998, when Kaaren and Hays Biggs purchased Etbauer, a son of Silver Deputy who won the 1999 Rebel Stakes (gr. IIII).Consigned by Old South Farm, agent, the Grindstone filly was purchased by California high-tech executive David J. Shimmon. She was produced from the 6-year-old unraced Carson City mare Quiet City. The OBS Sale topper was purchased as a weanling for only $15,000 by Terry Oliver at the 1999 Keeneland November breeding stock sale. The consignor at Keeneland was Glennwood Farm, agent. Prior to the OBS sale, the filly worked a quarter-mile in :21 4/5.In all, 685 juveniles were sold over the sale's four days.
