O'Brien outlines Leopardstown plans Leopardstown host their renowned 'trial's day' this coming Sunday and it'll be another important afternoon for the Ballydoyle team as they finalise their classic plans. Talking after Master Speaker scored at Dundalk, Aidan O'Brien outlined plans. The County Wexford native said: "Battle Of Marengo will run in the Ballysax. He's in good form. We're happy with him and he's ready to start. "We've always liked him and he's progressed nicely over the winter. "The United States will run in the trial (the Leopardstown 2,000 Guineas Trial). He's in good form and ready to start as well. "Snow Queen (a Leopardstown 1,000 Guineas Trial contender) is in good form whilst Declaration Of War will probably run in the stakes race (the Listed Heritage Stakes). "George Vancouver (a Leopardstown 2,000 Guineas Trial entry) probably won't run." (GC & EM)
