Sealy Hill (foaled April 14, 2004 in Ontario) is a Canadian Thoroughbred racehorse who won three Sovereign Awards in 2007, including Canadian Horse of the Year. In 2013, she was inducted into the Canadian Horse Racing Hall of Fame.
Owned and bred by Canadian businessman Eugene Melnyk, Sealy Hill was named for a village in the Melnyk's adopted home, Barbados. She was sired by 2001 American Horse of the Year, Point Given. Her dam is Boston Twist, a daughter of the 1996 American Champion Two-Year-Old Colt and Breeders' Cup Juvenile winner, Boston Harbor.
Trained by Mark Casse, as a two-year-old, Sealy Hill got her first stakes win in the 2006 Glorious Song Stakes. In 2007, after defeating the highly regarded Panty Raid in the Bourbonette Breeders' Cup Stakes at Turfway Park in Kentucky, she finished far back of winner Rags to Riches in the Kentucky Oaks at Churchill Downs. Back home in Canada, the filly returned to form, winning four stakes races while becoming the first-ever winner of the Canadian Triple Tiara. On grass she earned a second in the Grade I E. P. Taylor Stakes and the GII Canadian Stakes.
Casse said she was a temperamental filly who was her own worst enemy, especially in the starting gate. “Her mood swings and antics changed from minute to minute. You never knew which direction she was going to go, what she was going to do. At times she was more concerned with running over the competition than actually running by them.”
