Aidan O’Brien and Ryan Moore Join Forces in Epsom’s Blue Riband Trial with Six Horses Declared

The three-year-old was last seen chasing home Qipco 2,000 Guineas contender Ancient Wisdom in the Group 3 Autumn Stakes at Newmarket over a mile in October. Chief Little Rock got off the mark at the second attempt at Leopardstown in August before finishing second to Deepone in the Group 2 Beresford Stakes in September.

His trainer first landed the Blue Riband Trial in 2019 with Cape Of Good Hope, who went on to finish fourth behind Sottsass in the Prix du Jockey Club at Chantilly. “He’ll improve for the step up in trip and the course should suit him,” the trainer said.

“The owners have always been focused on trying to find Derby horses and this race will help give us an idea of what he could be capable of. He’s definitely a late developer and he’s strengthened a lot over the winter.”
