Now standing in Japan at Shadai Farm, Harbinger, a son of Dansili out of the Bering mare Penang Pearl, won six of his nine starts for Sir Michael Stoute and Highclere Thoroughbred Racing, including Royal Ascot’s Hardwicke Stakes in record time.

Standing for a fee of ¥3,500,000 (approximately £20,000), Harbinger has proved popular with Japanese breeders and covered in excess of 200 mares in each of his first two seasons at stud.

He has had nine runners to date in Japan and has had three placed horses along with the Northern Racing-bred winning colt Suave George.
