Overview
Unbridled's Song (February 18, 1993 – July 26, 2013) was an American thoroughbred racehorse who won the Breeders' Cup Juvenile, Florida Derby and Wood Memorial. He was the favorite for the 1996 Kentucky Derby but suffered a cracked hoof in the weeks before the race and finished fifth. He finished his racing career with five wins from twelve starts and earnings of $1.3 million. He subsequently became a highly successful sire, with major winners including Breeders' Cup champions Arrogate, Forever Unbridled, Midshipman and Liam's Map. He also sired the filly Eight Belles who came second in the Kentucky Derby. He was posthumously the leading sire in North America of 2017.
Background
Unbridled's Song was a gray stallion who was bred in Kentucky by Richard Eamer's Mandysland Farm. He was sired by 1990 Kentucky Derby winner Unbridled, whose other important offspring included Derby winner Grindstone, Preakness winner Red Bullet and Belmont Stakes winner Empire Maker. His dam, Trolley Song, is a winning daughter of Caro out of Lucky Spell, a stakes winner and stakes producer.
Unbridled's Song was sold as a yearling in 1994 for $200,000 to Ernie Paragallo who then "pinhooked" the horse as a two-year-old in training for a world record $1.4 million. However, the high bidder returned the colt after his veterinarian detected a bone chip, a claim disputed by Paragallo. Unbridled's Song subsequently raced for Paragallo's Paraneck Stable.
At maturity, he reached high. He was trained for most of his career by Jim Ryerson before being handed over to Nick Zito for his final two starts.
