Aidan O'Brien's So You Think, winner of the Prince of Wales's Stakes at Royal Ascot, heads 15 acceptors for the Coral-Eclipse at Sandown on Saturday - which could be the superstar's final run before taking up stallion duties.

The former Australian champion is currently the odds on favourite for this £400,000 contest at 3.45pm, which is part of the British Champion Series and run over one mile and two furlongs (2000 metres). O'Brien has also left in Daddy Long Legs, Windsor Palace and Robin Hood.

The lightly-raced four-year-old Farhh, who was an unlucky third in the Prince of Wales's Stakes when he made the leap from handicaps to Group 1 company, is a supplementary entry for Saturday's big race.

Farhh is trained by Saeed bin Suroor and his Godolphin counterpart Mahmood Al Zarooni could be represented by Dubai World Cup winner Monterosso and City Style.

The in-form John Gosden has earmarked the race for last year's King George winner Nathaniel while Sir Henry Cecil's multiple Group 1 winner Twice Over is also a likely runner.

Andrew Balding's Bonfire (a disappointment in the Investec Derby) and Brian Meehan's Cogito are the three-year-old possibles, along with Daddy Long Legs.

The only overseas possible is Alain de Royer-Dupre's Giofra while Roger Charlton's globetrotter Cityscape, who won the Dubai Duty Free before disappointing in Hong Kong, and Marco Botti's Crackerjack King are other creditable contenders along with Sri Putra.

Sir Michael Stoute's Carlton House was an expected absentee along with Cecil's star colt Frankel and Queen Anne Stakes runner-up Excelebration.

Supporting races on Sandown's seven-race card include the Group 3 £55,000 Coral Charge at 2.05pm, over the minimum five-furlong trip (1000 metres), and the £70,000 Coral Challenge, a hot handicap over one mile (1600 metres) at 2.40pm.

Elsewhere in the North of England , Haydock Park hosts a tremendously competitive seven-race card.

The all-age Group 2 £80,000 Bet365 Lancashire Oaks run over a mile and a half (2400 metres) is due off at 2.55 pm. Notable entries include the three-year-old Great Heavens from the all conquering John Gosden yard and the highly rated four-year-old Testosterone from Ed Dunlop's yard.

An interesting runner in the £100,000 Bet365 Old Newton Cup at 3.25pm, again over one mile and four furlongs (2400 metres), could be Donald McCain's lightly raced four-year-old Lexi's Boy.

McCain is making a habit of capturing major middle and longer distance handicaps as he did last Saturday when, on GBI Racing, his Ile De Re landed a nationwide gamble in the Northumberland Plate.
