AIDAN O’BRIEN hailed So You Think as “an incredible specimen of a thoroughbred” after his latest success in the Red Mills Irish Champion Stakes at Leopardstown on Saturday.

The Australian import has made a huge impact since joining O’Brien and has now won three Group Ones following earlier wins in the Coral-Eclipse and the Tattersalls Gold Cup.

Sent off the 1-4 favourite under Seamie Heffernan, the five-year-old had to work hard for victory to hold of the determined challenge of the Ed Dunlop-trained Snow Fairy.

Options remain open for So You Think with all the top autumn races from a mile to a mile and a half possibly on the agenda.

O’Brien said: “It’s a long time since he ran, and you’d always be worried about that.

“We’ll discuss things during the week now as to where he’ll go next.

“He cruises through his races and all options are open to him.

“He is an incredible specimen of a thoroughbred.”

John Magnier, of the Coolmore triumvirate, added: “He’s the kind of a horse who we are spoilt for choice with options.

“He could run in the mile race at Ascot (Queen Elizabeth II Stakes), the mile-and-a-quarter race (Qipco Champion Stakes, Ascot), or he could run in the Arc.”

Of a potential return to Australia, Magnier added: “You could never say never, but it’s not imminent.”

Derrick Smith, also of Coolmore, continued: “The English Champion and the Arc are there for him and we’ll leave it to Aidan now.”
