Death of Big Brown's
sire Boundary aged 22
BOUNDARY, sire of the Kentucky Derby hero Big Brown and Aidan O'Brien's Middle Park Stakes winner Minardi, was put down at Claiborne Farm in Kentucky on Saturday due to the infirmities of old age. The son of Danzig was 22-years-old and had been living in retirement at the farm since 2005.
He had been in good condition until the weekend, according to farm spokesman Bernie Sams.
Boundary retired to Claiborne in 1995 following a racing career in which he won six of eight starts including the Grade 3 Phenomenen Stakes and Grade 3 Roseben Handicap for breeders Claiborne Farm and William H. Perry's Gamely Corporation.
Boundary stood for a high of $30,000 in 1999 but otherwise his fee fluctuated between the $10,000 - $15,000 mark during a successful stud career which yielded 26 stakes winners.
His major runners are headed by the 2008 Kentucky Derby and Preakness Stakes winner Big Brown, whose first crop are two-year-olds, and the 2000 champion British and Irish champion two-year-old colt Minardi, a $1.65 million yearling purchase by Demi O'Byrne who captured the Group 1 Phoenix and Middle Park Stakes.
Another son, Grade 1 King's Bishop Stakes Pomeroy, is the sire of last season's Grade 1-placed filly Pomeroy's Pistol from his first crop.
Boundary has been represented as a broodmare sire in Europe by the Group 3-winning juveniles Long Lashes and Jupiter Pluvius.
Out of the Grade 3-winning Damascus mare Edge, Boundary was a brother to the Listed-placed Danzig's Edge.
Boundary has been buried at Claiborne.
