Boundary, sire of Big Brown, euthanized

LEXINGTON, Ky. – Boundary, the Claiborne Farm stallion who sired 2008 Kentucky Derby and Preakness winner Big Brown, was euthanized Feb. 4 due to the infirmities of old age, according to the Paris, Ky., farm. Boundary, by Claiborne’s late sire Danzig, was 22. He had been pensioned at Claiborne since 2005.

Big Brown, the 2008 champion 3-year-old, was Boundary’s most famous son. He won the Derby and Preakness but was pulled up in the Belmont Stakes. He now stands at Three Chimneys Farm in Kentucky. Boundary also sired English and Irish juvenile champion Minardi and Grade 1 winner Pomeroy.

Boundary was out of the Damascus mare Edge. He was a homebred for Claiborne and William H. Perry’s The Gamely Corporation. For that partnership he won the Grade 3 A Phenomenon and Roseben handicaps in 1994. He also placed in the Grade 2 True North and Tom Fool that year and closed the book on his racing career with wins in six of eight lifetime starts for earnings of $217,777. Boundary began his stud career at Claiborne in 1995.

His owners have buried Boundary at the farm.
