With the victory, Ad Valorem remained undefeated in three career starts and was installed as one of the favorite for next year's classic Two Thousand Guineas (Eng-I)."It didn't look like he was stopping and was holding on strongly," O'Brien told Racing Post. "Jamie thinks he will stay further than six, but the colt has a lot of natural speed too."
Mrs. John Magner's Ad Valorem, a 2-year-old son of Danzig--Classy Woman (by Relaunch) gave trainer Aidan O'Brien his group I victory of the British racing season with an impressive victory in the Shadwell Stud Middle Park Stakes (Eng-I) at England's Newmarket racecourse.Ridden by Jamie Spencer, Ad Valorem was well-placed near the front as Prince Charming set the early pace. Ad Valorem was set down for the victory a furlong from the finish and held off a fast-closing Rebuttal, a U. S.-bred son of Mr. Greeley for a three-quarter length triumph. The final time for six furlongs was 1:12.19 as favored Iceman finished third.Bred in Kentucky by Calumet Farm, Ad Valorem was purchased by Thomas Magnier for $450,000 from his breeder's consignment to the 2003 Fasig-Tipton Saratoga selected yearling sale.
