Odds-on favourite Camelot will face just eight rivals in the Investec Derby at Epsom today.
Aidan O'Brien's star three-year-old flew home from the rear to claim the 2000 Guineas at Newmarket earlier this month and he is a warm order to complete the same Classic double achieved by Sea The Stars in 2009.
The Ballydoyle trainer saddles just one other runner in Astrology, a runaway winner of the Dee Stakes at Chester.
The highest-rated British contender is the Andrew Balding-trained Bonfire, who won Britain's most prestigious Derby trial, the Dante Stakes at York.
Balding also runs outsider Minimise Risk.
David Lanigan's Main Sequence secured his fourth victory from as many starts in the Lingfield Derby Trial, which was this year notably run on the all-weather surface as the turf course was unraceable.
The third home at Lingfield, Marcus Tregoning's Cavaleiro, reopposes this weekend, with Hayley Turner taking the ride for the first time.
Richard Fahey saddles his first ever runner in the famous race in Chester Vase winner Mickdaam, the mount of champion jockey Paul Hanagan.
John Gosden has an interesting contender in Thought Worthy, while Rugged Cross from the Henry Candy stable completes the field in the smallest turnout for the Classic since 1907.
