Cook on top as O'Briens dominate It was Aidan first, Joseph second and Aidan third and fifth as the O'Briens dominated the Irish Stallion Farms EBF (C & G) Maiden (Plus 10 Race) at Leopardstown. James Cook (4/7) got the job done under Seamie Heffernan. The Lloyd Williams-owned and Joseph O'Brien-trained Latrobe ran very well on debut, but the previous second placer James Cook saw it out well enough to hold on by half a length. There was also merit in the performances of Ballydoyle third and fifth, Gardens Of Babylon and Cypress Creek. Johnny Murtagh's Machiavelli took fourth position.   Aidan O'Brien said afterwards: "He's still very green from the front but you would have to be happy with that. He probably won't run again this year. We will probably leave him alone." (AM & EM)
