Satish and Anne Sanan's Padua Stables, which ranks among the leading buyers of yearlings in North America, will not be participating in the Keeneland September yearling auction that begins on Monday in Central Kentucky.. Last year in September, Padua was the eighth-leading buyer in terms of gross expenditures, paying $3,925,000 for seven horses."We have a business plan in place, and we achieved our quota (for yearlings) at the Fasig-Tipton Kentucky and Saratoga sales," Satish Sanan said on Friday morning.He added that in the past, Padua had focused its buying efforts in September on the sale's two select sessions, pursuing yearlings for seven-figure prices. But under its new business plan, which was inaugurated last year, Padua is buying fewer of the top-priced, select horses and spending more in the $300,000 to $600,000 range. Sanan also acknowledged at Saratoga that the volatile stock market had impacted Padua's spending this year.Sanan said Padua would be buying mares later this year at the fall mixed sales and probably would be shopping next year for racing prospects at Calder and Barretts."We'll still be active," he said.Padua was the leading buyer at this year's Fasig-Tipton Kentucky July and Saratoga sales. The stable also topped the buyers' list for the Ocala Breeders' Sales Co. yearling auction's select sessions. Padua paid $2,167,000 for 12 horses at Fasig-Tipton Kentucky, $2,205,000 for eight horses at Saratoga, and $314,000 for four horses at OBS.
