Aidan O'Brien unleashes Derby and Oaks contenders

Both the Epsom Derby and Epsom Oaks have been dominated by Aidan O'Brien since the late 1990s and this year looks like it could be much of the same.

With just one runner in both the 1000 and 2000 Guineas last weekend, O'Brien's Classic season got off to an uncharacteristically muted start.

Any notion that would continue was quickly put to bed as he landed a Cheshire Oaks and Chester Vase double on Wednesday.

Thursday only made the Epsom Derby picture more ominous for rival trainers as Mount Kilimanjaro was rousted up the straight by Ryan Moore to land the Dee Stakes.

All three winners have thrust themselves firmly into the Classic picture.

Lambourn - O'Brien's Chester Vase winner - is 14/1 for the Derby, whilst Mount Kilimanjaro is a 20/1 chance.

Cheshire Oaks victor Minnie Hauk is 8/1 to win the fillies' equivalent at Epsom.

Clearly, Ballydoyle already have plenty of ammunition to fire in Surrey come the beginning of June, but it could get even better still after this weekend's Derby and Oaks trials at Lingfield.

Who are Aidan O'Brien's Classic Trial runners?

Giselle

By Frankel and out of Group 1 winning mare Newspaperofrecord, this three-year-old is currently 20/1 to win the Epsom Oaks.

She showed some decent form last season, finishing a close second to Bedtime Story in her maiden before concluding the campaign a comfortably beaten third behind stablemate Whirl in a Group 3.

With just two rivals to beat at Lingfield, she is a hot favourite to land the spoils on Saturday.

Puppet Master

One of two in the Derby Trial for O'Brien, Puppet Master is the all-important choice of stable jockey Ryan Moore.

He wasn't sparkling as a two-year-old, winning just once from his three starts but he made a nice return behind Delacroix in the Ballysax at Leopardstown in late March.

Stay True

Richard Kingscote is the beneficiary of Ryan Moore's decision to ride Puppet Master as he gets the leg up on Stay True.

By Derby winner Galileo he did not race as a two-year-old with connections instead opting for a early season maiden just last month.

Stay True rallied gamely to beat Ger Lyons-trained Game Point at Leopardstown.

The three-year-old doesn't hold an entry in the Epsom Derby but instead has the option of the Irish equivalent that falls later in the season.
