Glowing Tribute, the dam of Kentucky Derby (gr. I) winner Sea Hero and six other major stakes winners, died Aug. 5 of colic. One of the top broodmares of recent times, the 31-year-old daughter of Graustark was owned by John R. Gaines at the time of her death.She was boarded at Waggoner Farm near Lexington."I always found myself to be very privileged to have purchased Glowing Tribute from the Paul Mellon consignment at the Keeneland breeding stock sale in 1992," Gaines said. "She was a foundation mare of Mr. Mellon's famous Rokeby Stables, was certainly one of the premier broodmares of her time, and was voted Broodmare of the Year in 1993."Bred by Mellon, Glowing Tribute gave him one of his greatest thrills in a lifetime of breeding and racing when her son Sea Hero (by Polish Navy) won the 1993 Derby. For trainer Mack Miller, Sea Hero also won the Travers (gr. I) and Champagne Stakes (gr. I) and earned $2,929,869.She produced five other grade/group stakes winners: Hero's Honor (by Northern Dancer), Wild Applause (by Northern Dancer), Glowing Honor (by Seattle Slew), Coronation Cup (by Chief's Crown), and Mackie (by Summer Squall).She was carrying Mackie when Gaines purchased her for $460,000. Besides Mackie, she produced just two other foals since. She was last bred in 2001.Out of the Hail to Reason mare Admiring, Glowing Tribute won nine of 24 starts during her racing career. In 1976, she won the Diana Handicap (gr. IIT) and a division of the Sheepshead Bay Handicap (gr. IIT), and came back to also win the latter in 1977.Her name is prominent in many pedigrees today. For example, her son Hero's Honor, is the broodmare sire of Elusive Quality, the sire of this year's Derby and Preakness Stakes (gr. I) winner Smarty Jones. Also, her daughter Wild Applause is the dam of four stakes winners including Yell, who runs in today's Honorable Miss (gr. II) at Saratoga.
