Sariska and Midday, first and second in the Epsom Oaks last month, are set to do battle again at the Curragh on Sunday when they line up for the Darley Irish Oaks. Both fillies have been supplemented to the Group 1 Classic at a cost of €50,000 each. The race has attracted a total of twelve fillies including John Oxx's unbeaten Beauty O'Gwaun.
