Chester House, the son of Mr. Prospector who won the Aug. 19 Arlington Million Stakes (gr. IT) as a homebred for Khalid Abdullah’s Juddmonte Farms, is likely to enter stud at the farm’s North American division near Lexington in 2001. A group winner in England, Chester House is scheduled to close out his career in the Nov. 4 Breeders’ Cup Classic (gr. I) at Churchill Downs. He ran fourth in last year’s running in his first start following his arrival from England.“It’s 99.9% certain he will enter stud next year,” said farm manager Garrett O’Rourke, who added that a possibility exists that Chester House will remain in training if he wins the Classic in overwhelming style. Chester House currently is tied with Montjeu and the recently retired Dubai Millennium in the International Emirates Racing Series. The Classic is a part of the series. “Chester House is a good-looking, strong horse with good bone,” O’Rourke said. “He proved last year in the Classic that he could compete on dirt at the highest level. He’s a son of Mr. Prospector out of a fantastic (female) family and is racing during a year in which Fusaichi Pegasus (by Mr. Prospector) was valued at $60 million for stud.”Chester House’s dam, Toussaud (by El Gran Senor), was a grade I winner in Southern California for Juddmonte, and his 4-year-old half-sister, Honest Lady, is a grade I winner. Chester House, who placed in three graded stakes this year, has won six of 21 starts and earned $1,944,545.
