LEXINGTON, Ky. – It will be a once-in-a-lifetime race – literally. Although the $125,000 Keeneland 75th Anniversary Stakes might eventually be run every fall meet under a different name, its unveiling here Saturday carries the one-time purpose of celebrating the founding of this pastoral track on Oct. 15, 1936, while also getting some serious prep work done toward the 2011 Breeders’ Cup.
