Owen and Georgina Rinehart’s Isinya HDC (horse development corporation) was essentially started in 1993. With Georgina’s insight and love of animals her dream of having foals running around the farm started with the purchase of Amber Shoes, a Topsider stallion bred by the Centennial farms of New York. Owen first viewed Amber Shoes playing at Vero Beach polo club for Adam Snow and after the purchase took him to California in 1993 to play in the U.S. open.
He produced many foals that went on to play in high goal polo, not only for Owen but for high goal sponsors such as John Goodman, Skeeter Johnston, Michael Price and Melissa Ganzi. The Busch’s and Orthwein’s jumped on board and sent mares to be bred to Amber Shoes. His foals have raked up numerous Best Playing Pony awards in Florida and South Carolina.
In 1996 Dicky and Francis Santamarina generously gave an agricultural award winning stallion to the Rineharts to continue the famous La Fortuna line in the United States. This stallion’s name was Lord Franco. His foals are just coming into their own in Florida playing in the 22 and 26 goal polo. In 2007 Owen’s horses won the Best String in the US Open and 4 out of the 7 were Lord Franco’s Offspring.
In 1999 River became the next generation of polo stallions. He was the son of Amber Shoes and New Zealand bred Angie. River followed in his father’s foot steps by being one of a few polo playing stallions. An injury as a foal prevented him from realizing his full potential that his BPP full sister and brothers have but his incredible heart and intelligent mind made him ideal for not only Owen to play but for Georgina also. Sponsors and Pros that played Amber Shoes babies have sent their mares to River to continue on the Isinya line. His babies have already gone on to win BPP in Aiken and are playing in 26 goal in Florida.
Not to be out done, Dicky SantaMarina offered to Georgina the pick of the stallions on a visit to Argentina in 2000. She picked Lord Lizard. As it turned out he is by the same stallion as Aiken Cura the 2005 and 2006 BPP for Palermo’s Susan Townley Trophy. The stunning almost Black stallion has amazing strength and athletic ability. With the solid La Fortuna breeding behind him he has all the ability to carry on the La Fortuna line in Aiken. His babies are showing his speed, athleticism and love of Polo.
RiverDance has followed in his fathers and grandfathers footsteps by playing and breeding. His first season in Florida he would play for Owen then load up in the trailer and go play PeeWee polo for Mike Azzaro’s 10 year old son. He has won Best Playing Pony in both the Skeeter and Hitchcock Memorials all before the age of 8. His foals are carrying on the incredible easy and intelligent attitude he possess.
In 2005 Owen was awarded Best Mounted Player for the whole tournament in the 26 goal Gold Cup with 6 out of 8 of his horses from the Isinya horse development corporation.
In 2007 Owen received the highest award of the year for winning the best mounted player in the U.S. Open, with 7 out of the 8 horses being homebreds.
In 2009 Owen’s Isinya HDC was awarded best breeder of the year by the American Polo Horse Association (APHA).
The Isinya line is being carried on by Stallions like Aslan, son of Lord Franco and Angie, Lord Easy son of Lord Franco and Cool N Easy, RiverDance son of River and Local Dancer, Pi son of River and Lady Laurine and more young stallions up and coming.
