Aidan O'Brien is responsible for the six of the 16 five-day entries for Saturday's Dubai Dewhurst Stakes as he seeks to win the seven-furlong race for a third time.
The Ballydoyle trainer, successful with Rock of Gibraltar (2001) and Beethoven (2009) has a strong team headed by National Stakes victor Power and recent Royal Lodge Stakes winner Daddy Long Legs, while Reply, David Livingston, Nephrite and Tibet complete his list of possible runners at Newmarket.
Power, Reply, Nephrite and George Margarson's Rebellious Guest have also been left in the six-furlong Middle Park Stakes on the same card.
Spiritual Star, trained by Andrew Balding, was the sole supplementary entry at the confirmation stage. The Soviet Star colt looked good when opening his account by six lengths in a maiden over the course and distance last month.
Jim Bolger landed a hat-trick of successes in this race with Teofilo, New Approach and Intense Focus from 2006 to 2008 and looks to Parish Hall this time.
Richard Hannon has surprisingly not won this race but looks to have two decent prospects in the unbeaten Bronterre and Champagne Stakes winner Trumpet Major. A top-quality entry is completed by Ektihaam, Factory Time, Fencing, Most Improved and Red Duke.
Spiritual Star is owned by Thurloe Thoroughbreds, who were happy to stump up the cash for a crack at the Dewhurst.
"Spiritual Star won very nicely at Newmarket and he looked like a potentially smart horse in the making," said their racing manager James Stafford.
"We are very thrilled with him and we are stepping a little bit into the unknown but Jimmy Fortune said that he deserved a go in a Group race. We had the option of going to Newmarket or waiting until the Horris Hill Stakes (October 22) at Newbury and we thought that we would run him while he is in such good form."
