O'Brien-trained Starspangledbanner retired to stud

Royal Ascot winner and European champion sprinter-elect Starspangledbanner has been retired to stud at Coolmore for the 2011 season.

The Aidan O'Brien-trained four-year-old proved a huge hit following his transfer from Australia, winning the Golden Jubilee Stakes at the Royal meeting and following up in the July Cup at Newmarket.
