Argo Navis
On 16 September, Miss Jummy started the 6/4 favourite for the Park Hill Stakes over the St Leger course and distance in which she was set to concede six pounds to her principal opponents Argo Navis and the Yorkshire Oaks winner Philosophy. Miss Jummy tracked the leaders before taking the lead approaching the final furlong. She was immediately challenged by Argo Navis and the two fillies raced together throughout the final furlong with Miss Jummy prevailing by a neck over her old rival. The winning time of 3:20.5 was almost a second faster than that recorded by Ormonde, carrying five pounds less, in the St Leger two days earlier.
