Monarchoftheglen, a $1.5 million Coolmore yearling purchase in 2000, died March 11 from apparent heart failure after finishing last of eight in a six-furlong claiming race at Mountaineer Park. The 7-year-old gelding, by A.P. Indy out of the Alydar mare Milliardare and trained by Bart Baird, collapsed in the paddock following the race. He had been claimed by Bradley Thoroughbred Enterprises LLC for $5,000. Acquired by Coolmore at Keeneland's July yearling sale in 2000, Monarchoftheglen was shipped to Ireland, where he broke his maiden first time out and raced to a game third-place finish in the Chesham Stakes and fourth-place finishes in the National Stakes (Ire-I) and King of Kings Futurity (Ire-II). A three-quarter brother to multiple grade I-winning filly Lakeway, he returned to the United States in 2001 and made his dirt debut on Gulfstream Park's Fountain of Youth undercard, finishing second to Nick Zito trainee American Style.
Nominated to the 2002 Triple Crown races as well as the Wood Memorial and Bluegrass Stakes (both gr. I), Monarchoftheglen raced for trainer Niall O'Callaghan on that year's early Triple Crown trail but failed to start in the significant spring races. He went on to earn a career total of $141,204, mostly in allowance and claming races, with a 7-9-4 record from 36 starts.
