O'Brien ready for UAE Derby Battle Aidan O'Brien bids to improve on an already impressive UAE Derby record with Lines Of Battle. Ballydoyle only returned to support the meeting very recently, with Master Of Hounds touched off in this three-year-olds only event in 2011, while Daddy Long Legs went a place better 12 months ago. Lines Of Battle, another with an American pedigree, won on the Polytrack at Dundalk before finishing seventh to stablemate George Vancouver in the Breeders' Cup Juvenile Turf. "He's trying a new trip and a new surface, said O'Brien. "But he won well on Polytrack at Dundalk last year and we're happy with him for his first run of the year." David Marnane's Elleval gives another Irish involvement.
