Best Of Bordeaux has been absent from the racetrack since last spring and Coolmore on Thursday announced that his racing days were over with the Golden Slipper runner-up to stand at stud this year.

The son of Snitzel's summer/autumn campaign was aborted early after he contracted pneumonia, which ensured he was unable to add to racing record that features two Group 2 wins and a couple of Group 1 placings.

But the rising four-year-old is fit to go at stud and will be a welcome addition to a Coolmore roster that includes two other Silver Slipper winners, Pierro and Home Affairs.

"Like his sire, Best Of Bordeaux was a natural, forward-running speed horse, faster and more accomplished at two than other effective sire sons of Snitzel such as Shamus Award and Russian Revolution," Coolmore Australia's Tom Moore said.

"Best Of Bordeaux has a wonderful group of leading breeders involved in his ownership, each of whom will support him with quality mares.

"He was bred by Gerry Harvey who remains in the ownership, and we feel that he is the perfect horse for breeders to target, with sales like the Magic Millions January yearling sale in mind."

Best Of Bordeaux was the highest-rated two-year-old colt of his generation on the Timeform scale, ending his juvenile season with a peak figure of 115, which was two pounds higher than the only Group 1-winning colt of that season – Blue Diamond victory Daumier (113).

That peak rating came when second in the Golden Slipper, which followed wins in the Group 2 Silver Slipper and Group 3 Canonbury Stakes.

The Kacy Fogden-trained colt lifted that peak rating to 116 with his first win as a three-year-old, in the Group 2 Roman Consul Stakes, while he added a weight-for-age Group 1 placing to his resume with his Manikato Stakes third on Cox Plate Day.

Best Of Bordeaux will stand at Coolmore's Jerry's Plains property in the Hunter Valley at $27,500 a serve.
