Delta Princess, dam of Royal Delta, euthanized at age 15

Delta Princess, the dam of champion distaffer Royal Delta, was euthanized on Tuesday due to a degenerative stifle condition at the age of 15.

By A.P. Indy out of the Group II winner Lyphard’s Delta, Delta Princess was a multiple graded stakes winner on the track, retiring with earning of $740,918. It was in the breeding shed where she truly distinguished herself, producing three graded stakes horses from her first four foals, including three-time Eclipse Award winner, Royal Delta.

Royal Delta captured back-to-back editions of the Breeders’ Cup Distaff in 2011 and 2012 and retired with 12 wins from 22 starts and $4,811,126 in earnings. Days after her first Breeders’ Cup triumph, Royal Delta was purchased for $8.5 million by Ben Leon at the 2011 Keeneland November Breeding Stock sale, the same auction in which Adena Springs purchased Delta Princess for $2.6 million.

“It is with great sadness that we had to humanely euthanize Delta Princess early this morning,” said Adena Springs’ general manager, Eric Hamelback. “Her chronic stifle issue caused her significant discomfort overnight and it was clear that it was our only course of action. She was a remarkable producer throughout her career and we are all deeply saddened that it was cut so short.”

Beyond Royal Delta, Delta Princess’ produce have been highly sought-after at the sales. Her daughter Crown Queen sold as a weanling for $1.6 million at the same  2011 Keeneland November sale and her current two-year-old son Khozan sold for $1 million at the Fasig-Tipton March 2-year-olds in training sale.

Delta Princess produced a colt by Street Cry in 2013, and was barren for 2014. She was in foal to Awesome Again at the time of her death.
