LEXINGTON, Ky. − Kentucky’s Thoroughbred auction houses had more rooting interests than usual at the Breeders’ Cup this year: 19 Breeders’ Cup runners also were entered in Lexington’s November mixed sales, which started at Fasig-Tipton on Sunday, the day after the Breeders’ Cup ended. The Breeders’ Cup’s effect on a runner’s sale price became obvious Tuesday, when 2011 Ladies’ Classic winner Royal Delta brought a stunning $8.5 million at Keeneland’s November auction.
