LOU2002050204 - LOUISVILLE, Ky., May 2 (UPI) -- Jockey Pat Day returns from winning the 8th race at Churchill Downs in Louisville, Ky., on May 2, 2002. Today's sloppy conditions will likely continue into the weekend, keeping Derby horses in the stables and setting up a muddy 128th running for the Roses. Day will ride Buddha on the May 4 Derby. rlw/Roger L. Wollenberg UPI
