So You Think's sire High Chaparral (IRE) has died in Ireland at age 15.
The six-time Group I winning son of Sadler's Wells had just returned from his Southern Hemisphere season at Coolmore Australia Jerry's Plains and was put down at Fethard Equine Hospital during exploratory colic surgery due to a perforated intestine.
A superior racehorse that won Group I events at two, three and four including the Epsom Derby and Breeders Cup Turf, twice, High Chaparral proved equally successful at stud.
Shuttling to Windsor Park Stud in New Zealand at the start of his stud career, High Chaparral made his mark first in the Southern Hemisphere with a string of top class Group I winners headed by So You Think, who won 10 Group I events and competed successfully all over the world.
High Chaparral has sired 61 stakes-winners, 11 of which are Group I winners with So You Think joined by other star performers such as Dundeel, Shoot Out, Toronado, Descarado and Monaco Consul, etc.
He is also making an impact as a broodmare sire, his daughters producing this year's French Group I winning two year-old The Wow Signal (by Starspangledbanner) and Suavito, winner of the Group II Matriarch Stakes.
High Chaparral has a dozen entries at the 2015 Magic Millions, where the first yearlings by So You Think will also make their sale ring debut.
