O’Brien’s son Joseph is given the opportunity to claim his first British Group One on clear stable first choice Await The Dawn.
The junior O’Brien has taken advantage of the injury to Ryan Moore and the lack of a stable jockey at Ballydoyle and his father picked him for Await The Dawn, who is lightly raced and has looked a star in the making as a four-year-old in the Huxley Stakes at Chester and the Hardwicke Stakes at Royal Ascot.
The teenager rode his first Classic on Roderic O’Connor in the Irish 2000 Guineas, but that one will be partnered by Colm O’Donoghue, and is on a retrieval mission after the French and Irish Derby.
Windsor Palace and Seamie Heffernan are set for pacemaking duties.
“I haven’t ridden him in a race but I know him well at home,” Joseph O’Brien said of Await The Dawn.
“He’s a lovely, big horse and you’d say he was very uncomplicated.
“His form looks good from Ascot, so hopefully he will run well.”
Khalid Abdullah yearns to win the race he sponsors and has encouraged trainer Henry Cecil to field both Midday and Twice Over, who will give O’Brien a stiff challenge.
He almost won it with Twice Over last year before he was pipped to the post by O’Brien’s Rip Van Winkle and his three-time Group One winner quelled a dip in his form this season by striking in the York Stakes over course and distance last month.
Cecil’s stable jockey Tom Queally, however, has opted to ride the outstanding mare Midday after she claimed the Nassau Stakes for the third year in a row.
“This is a race everyone connected with Juddmonte would dearly like to win, not least of all the boss, and he is sending his two currently most suitable and ready horses to go,” said the owner’s racing manager Teddy Grimthorpe.
“I think Tom would have preferred not to have made the decision (which horse to ride), but the way Midday came back at Goodwood was very pleasing.
“I wish we had 20 more like Twice Over as he has been such a reliable, genuine, charming horse.
“He’s still tremendously enthusiastic in his work and goes really nicely.
“The filly still likes it as well, so we’re giving it our best shot.”
