Coolmore has announced that dual Group 1-winning two-year-old Puerto Rico has retired to stand at Castlehyde Stud for the 2027 breeding season.

Trained by Aidan O'Brien, the outstanding juvenile sparked a dominant and flawless autumn hat-trick by winning the Group 2 Champagne Stakes at Doncaster. He proceeded to capture the Group 1 Prix Jean-Luc Lagardère over seven furlongs by two and a half lengths, and doing so in a faster time than his late sire, Wootton Bassett.

Surpassing his sire's own race record, Puerto Rico then completed back-to-back French Group 1 victories with a straightforward win in the Group 1 Critérium International over a mile at Saint-Cloud.

From an outstanding family of champions and multiple Group 1 winners, Puerto Rico is out of the Group 2-placed Galileo mare April Showers, a full-sister to four-time Group 1 and classic-winning champion two-year-old Misty For Me and Prix Marcel Boussac heroine Ballydoyle.

It is the immediate family of multiple Group 1 winners Roly Poly and unbeaten European champion two-year-old Fasliyev.

Trainer Aidan O’Brien highlighted Puerto Rico’s resemblance to his sire: “Wootton Bassett himself had tremendous speed, and this colt has just as much of it. He reminds me a lot of him. He's a lovely, big, powerful, mature horse.”

Castlehyde Stud manager Paddy Fleming added: "Puerto Rico is the best two-year-old by Wootton Bassett, and the reality is that he was a better two-year-old than him. He brings incredible two-year-old form and one of the best pedigrees in the stud book to the roster. His fee will be announced this week and breeders can anticipate exceptional commercial value from a horse of this calibre."
