Four Irish among Derby Trial entries There is a strong Irish entry for Saturday's Betfred Derby Trial at Lingfield including two from Aidan O'Brien's Ballydoyle stable. He could run either Athens or Tower Rock while the John Oxx-trained Call To Battle and Ken Condon's Macbeth make up the Irish brigade. The John Gosden-trained Thought Worthy and Richard Hannon's Rougemont, second and third respectively behind O'Brien's Imperial Monarch in Sandown's Classic trial, could renew rivalry again on Saturday. Rae Guest's Ed De Gas and David Lanigan's Main Sequence have unbeaten records to defend while Andrew Balding has two good chances in Goldoni and Minimise Risk. Cavaleiro, a son of 2006 Epsom hero Sir Percy, bids to book his place in the premier Classic for that colt's trainer Marcus Tregoning. William Haggas' promising filly Vow is among 17 entries for the Betfred "The Bonus King" Oaks Trial on the same card. The daughter of Motivator won on her debut at Newbury last month to earn quotes of around 16-1 for the Investec Oaks which Haggas won last year with Dancing Rain. O'Brien has three possibles in Devotion, Soon and Twirl while other interesting includes Sir Mark Prescott's Albamara, Ralph Beckett's Colima, Paul Cole's Gifted Girl and Richard Hannon's Misdemeanour.
