So You Think has run his last race.
So You Think was found to be lame after exercise and appears to have pulled a muscle in his hind quarter which precludes him from running in the Eclipse Stakes on Saturday after which he was already due to retire.
He will enter quarantine on Saturday as originally planned and will stand at Coolmore Australia at a fee of Aus$66,000.
"So You Think is an extraordinary horse and it was a real privilege to have had him here at Ballydoyle on loan from Australia," said Aidan O'Brien (pictured with So You Think at Ballydoyle) who took over the son of High Chaparral from Bart Cummings to win the last five of his 10 Group 1's.
"It's a big disappointment that he'll miss the Eclipse, but he's had a wonderful racing career and now it's time for him to shine at stud," said Coolmore Australia's Tom Magnier.
"His book reads like a who's who of all the best mares and breeders so he'll get the best possible start."
So You Think retires as a 10-time Group I winner of $8 million in prizemoney and will be greeted by a stellar line-up of mares when he arrives in Australia this spring.
