Order Of St George completed a St Leger double for Aidan O'Brien with a runaway win under jockey Joseph O'Brien at the Curragh yesterday.
However, the race produced more sadness than jubilation after last year's winner, Brown Panther, owned by Michael Owen, sustained a fatal hind leg injury nearing the turn for home, reported the Racing Post.
The decision to reroute Order Of St George to the Irish St Leger instead of the Ladbrokes St Leger on Sunday proved an inspired move by connections as he eased to success, while Bondi Beach scored at Doncaster in his absence.
O'Brien anchored the well-backed 5-4 favourite at the back of the pack as Good Tradition set a solid pace, with Brown Panther taking up a role behind the leader.
The race changed approaching the turn for home as Richard Kingscote sent Brown Panther in pursuit of the leader, at which point disaster struck and the popular 7-year-old was pulled up. He could not be saved.
