Aidan O'Brien saddles three in attempt to improve Derrinstown record
Aidan O'Brien sends three colts into battle in a bid to extend his excellent record in the Derrinstown Stud Derby Trial at Leopardstown on Sunday.
The master of Ballydoyle has saddled 10 winners of this prestigious event since breaking his duck with Risk Material in 1998. He would go on to train nine of next 15 winners, with subsequent Epsom heroes Galileo (2001) and High Chaparral (2002) - as well as four-time Gold Cup victor Yeats (2004) - among those on the roll of honour.
