O'Brien 12 in Racing Post Trophy mix Aidan O'Brien has 12 horses in contention for Saturday's Racing Post Trophy at Doncaster as he seeks a record-breaking 26th Group One winner of the year. The Ballydoyle handler equalled Bobby Frankel's record with Hydrangea at Ascot on Saturday and is responsible for more than half of the entries in the mile contest. Spearheading O'Brien's potential team are leading Investec Derby fancies Saxon Warrior and The Pentagon. Mendelssohn, Seahenge and Threeandfourpence, who finished second, third and fourth respectively in the Dewhurst, have also been left in, along with Zetland Stakes winner Kew Gardens and Royal Lodge runner-up Nelson. Coat Of Arms, Delano Roosevelt, Hunting Horn, Lucius Tiberius and Saracen Knight complete his list of contenders. National Stakes winner Verbal Dexterity is one of two potential runners, along with Theobald, for trainer Jim Bolger. John Gosden's Royal Lodge winner Roaring Lion heads the home-trained team, while Charlie Appleby could be double-handed with Solario Stakes hero Masar and first-time-out Goodwood winner Loxley, who was the sole supplementary entry. The list is completed by Alfa McGuire (Bryan Smart), Chilean (Martyn Meade), Hey Gaman (James Tate), Gabr (Sir Michael Stoute) and Merlin Magic (David Elsworth).
