Lawyer Ron, winner of the Arkansas Derby, heads the list of nominees for the $250,000 St. Louis Derby, a 1 1/16-mile race at Fairmount Park on Aug. 26. Lawyer Ron is likely to start, as his trainer, Bob Holthus, hopes to use the St. Louis Derby as a stepping-stone to next month's Super Derby at Louisiana Downs, and then take a shot at the Breeders' Cup Classic at Churchill Downs.
