Homebuilder, a millionaire and sire of 25 horses that won or placed in stakes, has been euthanized because of a heart condition. The 21-year-old son of Mr. Prospector stood most of his career for the late breeder/owner John Franks and the last couple of years at Jay Adcock's Red River Farms near Coushatta, La.Homebuilder initially raced for his breeder, James P. Ryan. A home builder, Ryan campaigned Homebuilder in the name of Ryehill Farm and won seven stakes with him, chief of which was the 1988 Fayette Handicap (gr. II) at Keeneland. Shortly after winning the Fayette, Ryan sold Homebuilder as part of the Ryehill dispersal at the Keeneland November sale to help raise money to fund programs for backstretch workers. Bought by Franks, Homebuilder fetched the dispersal's second-highest price, $1.6 million.For his new owner, Homebuilder won the 1989 Baltimore Budweiser Breeders' Cup Handicap (gr. III) in what was his last season of racing. He retired with 30 stakes wins or placings from 60 starts and earnings of $1,172,153.Homebuilder stood several seasons at Josephine Abercrombie's Pin Oak Stud in Kentucky before being moved to Franks Farm (Southland Division) near Ocala, Fla. His 11 stakes winners included graded winners Built Up, who won or placed in 24 stakes, and Built for Pleasure, whose memorable victory came in the 1996 Fountain of Youth Stakes (gr. II) at 143-1.Homebuilder, who stood for a time at Ryder River Ridge Farm in Louisiana before moving to Red River, covered one mare this year before being euthanized in the spring. "She's in foal, and we're hoping it's a special foal," Adcock said. "We don't get too many millionaires down here, and it was a thrill standing a horse like Homebuilder."
