LEXINGTON, Ky. - Padua Stables owner Satish Sanan, who was notably absent at the Keeneland September yearling sale this week, will step down as head of the Alliance for Industry Reform to concentrate on his position as an owner representative on the new Sales Integrity Task Force. Sanan's announcement came three days after the sale of an auction-record $8 million Storm Cat colt to an unnamed buyer, a situation that highlighted AIR's proposal that selling and buying agents be required to disclose their clients' names in transactions.
