KING George VI and Queen Elizabeth Stakes runner-up Nathaniel was yesterday added to the Irish Champion Stakes field at Leopardstown at a cost of €20,000 to his owners.
The four-year-old Coral Eclipse winner was just denied in a thrilling King George at Ascot last Saturday and following his Irish Oaks winner on Sunday trainer John Gosden mentioned the Red Mills Irish Champion Stakes as a possible target.
Nathaniel was the only supplementary entry in the field of 33 that went forward after yesterday's latest forfeit stage.
Aidan O'Brien is, as expected, mob-handed for the Group One contest to be run on September 8 and heading the 11 Ballydoyle entries is three-time Classic winner Camelot, although he is a very unlikely participant with the Triple Crown attempt to be completed in Doncaster just a week later.
A more likely runner for the Ballydoyle outfit is St Nicholas Abbey, while there is some strong international possibilities with Cirrus Des Aigles, Monterosso and Snow Fairy all engaged.
Meanwhile, Doncaster are gearing up for Camelot on their Ladbrokes St Leger day as he headed the 36 entries for the race after it closed yesterday.
Camelot, a previous winner at Doncaster when winning the Racing Post Trophy as a juvenile, has won the Quipco 2000 Guineas at Newmarket and both the English and Irish Derby's this season.
He will bid to become the first horse since Nijinsky in 1970 to win the Triple Crown of the English 2000 Guineas, Derby and St Leger and sponsors Ladbrokes make him 2/5 to do so.
O'Brien has a total of 11 of the 36 entries for the race, while John Gosden, who will search for a third consecutive win in the race has entered five, including his Irish Oaks winner Great Heavens.
Doncaster are said to be delighted by the excitement surrounding Camelot's likely participation and report a massive surge in ticket sales since Aidan O'Brien's colt won the Irish Derby at the Curragh.
In a massive year for the British royal family, Queen Elizabeth also has an entry courtesy of Estimate, who was victorious at Royal Ascot in the Queen's Vase for Michael Stoute and Ryan Moore.
Hayley O'Connor of Ladbrokes commented: "We couldn't be happier after seeing the entries and although Camelot sets the standard, there are a number of top quality challengers that could make this an outstanding renewal of the race."
