Owen Burrows Wants to Assert a career win, on his move back up to Group Three Degree for Its John Guest Racing Stakes.
The colt has been carefully campaigned far, winning four times.
A measure up into Group business saw him beaten for the first time when 12th of 21 at the Jersey Stakes at Royal Ascot last year.
He bounced back to win the course and distance in his second beginning of Saturday over – and made an impressive return in August from a 10-month lack at Doncaster.
He is a horse with a great deal of ability, said Angus Gold, racing manager to owner Sheikh Hamdan Al Maktoum.
He desires easy ground, so that ought to suit him. He is only a horse to train. He has had plenty of difficulties, but hes a horse that is good.
We have not run him at a proper race, thus we cant tell, but hes possibly a smart horse.
Thrilla represents Richard Spencers Newmarket lawn, together with the three-year-old producing his reappearance.
The son of Iffraaj was a winner in his first and only start to date last October, when claiming a maiden at Newbury.
Were anticipating working on Saturday, said Spencer.
Hes a horse that has taken the time to come to hand this season, but we are hoping for a good run.
Elsewhere on the card, the Michael Dods-trained Dakota Gold leads the area for the Listed Rous Stakes over five furlongs.
The gelding finished half a length behind In India at the Group Three World Trophy Stakes last month, putting an end to his series.
He ran a terrific race at Newbury, explained Dods.
Connor (Beasley, jockey) just felt that, even though the floor was loose on surface, it was still quite firm underneath.
Hed have got off with it on six furlongs, but over five he just lacked that little fur. He will be all right on soft earth, which we understand he manages over five.
We will see how he goes. Hes had lots of rushing this year, but he seems well.
If Dakota Gold work nicely at Ascot, he can wrap up the year with a visit to Doncaster in November to contest the Proper Wentworth Stakes.
Dods added:If he comes out of the weekend nicely we might give him yet another run from the Listed race at Doncaster at the conclusion of the year – otherwise, well simply put him off before next year
