Mackie, who sold for big prices at auction, was euthanized March 18 because of foaling complications while delivering an offspring by Any Given Saturday . The foal also died. Mackie, a 16-year-old daughter of Summer Squall, was owned by Sheikh Mohammed’s Darley. Any Given Saturday stands at Darley near Lexington.
Bred in Kentucky by John R. Gaines, Mackie sold as a weanling for $550,000 at the 1993 Keeneland November breeding stock sale, for $5 million at the 2000 Keeneland January horses of all ages sale, and for $3,255,168 at the 2006 Tattersalls November sale. Her price at the 2000 Keeneland January sale when she was in foal to Mr. Prospector remains a sale record, and her price at Tattersalls when she was in foal to Unbridled's Song was the fourth-highest at the sale that year. John Ferguson Bloodstock bought her for Sheikh Mohammed at Tattersalls from Britton House Stud, agent.
Mackie, who was foaled several days before her half-brother Sea Hero won the 1993 Kentucky Derby (gr. I), raced for Dr. Thomas F. VanMeter and Ben P. Walden Jr. She was named for Walden’s mother, Margaret, Mac, whose nickname was Mackie.
Trained by Ben Walden’s brother, Elliott Walden, Mackie won the 1996 Busher Stakes (gr. III) at Aqueduct and placed in that year’s Ashland Stakes (gr. I) at Keeneland and the Fair Grounds Oaks (gr. III). She was retired after two years of racing with three wins from eight starts and earnings of $164,579.
Mackie, who was one of seven stakes winners out of 1993 Kentucky Broodmare of the Year Glowing Tribute (by Graustark), produced nine named foals, six of which are winners, including grade II winner Mr. Mellon (by Red Ransom), Japanese group winner Seeking the Best (by Seeking the Gold), and two stakes-placed runners. Seeking the Best sold for $1 million and Mr. Mellon fetched $950,000 at their respective Keeneland September sales.
