Sold late on the second day, the Mount Eaton Stud consigned colt fetched €165,000 when purchased by former champion jockey Mick Kinane on behalf of the Hong Kong Jockey Club.
"He is by the exciting sire No Nay Never, he is a lovely big horse who will need time," said Kinane. "It is nice to be able to buy one by the stallion."
The colt is out of Rio's Pearl, a Captain Rio sister to Listed winner Agony And Ecstasy and a half-sister to Medicine Jack (Equiano), winner of the G2 Railway Stakes and third in the G1 Phoenix Stakes.
Kinane, in his new role for the HKJC, also paid the top price on day one when he went to €100,000 for a colt by Holy Roman Emperor.
The two-day September Yearling Sale concluded with 388 lots sold for an aggregate of €9,415,500, a fall of 10% compared with 2018 but reflective of the 80-lot smaller catalogue.
The average price of €24,267 was just 5% off 2018's figure, while the median value of €20,000 was level with last year. The clearance rate over the two days was a strong 86% - up eight points on 2018.
