Iridessa has put herself in the spotlight ahead of next year's Classics, as she landed the bet365 Fillies' Mile at Newmarket on Friday. That result proved to be a landmark victory, with the daughter of Ruler of the World giving Joseph O'Brien his first Group One training success in Britain.
The 2-year-old filly had previously made a big impression when winning on debut at Killarney back in July, before a fifth placed effort in the Group 2 Debutante Stakes at the Curragh. That performance was then followed up by a third placed finish in a Listed race at Leopardstown.
It appeared that she would struggle with the step up into Group One company when reflecting on her previous performances, however she sprung a surprise much to the delight of her trainer, as Iridessa came home in first at 14-1 under jockey Wayne Lordan.
Iridessa, under a patient ride from Lordan, quickened up best going into the final furlong, holding off the efforts of Hermosa, to score by a length and a half. Michael Bell's Pretty Pollyanna finished another three-quarters back in third.
O'Brien speaking after the race said: "I couldn't say we expected her to win, but we always loved the filly and we expected her to run well.
"She did it well and Wayne gave her a great ride. She travelled well and I thought she quickened up well. We're delighted."
Betfair went 16-1 for Iridessa to land the Qipco 1000 Guineas, whilst some bookmakers made her a 20-1 fancy for the Investec Oaks.
O'Brien added: "She's definitely well entitled to line up in it (Guineas). Being by Ruler Of The World, she's probably more of an Oaks filly, but we'll get today out of the way and worry about that when the time comes.
"We'll enjoy today and give her a nice break through the winter and dream about next year."
His father, Aidan O'Brien added: "I'm delighted for Joseph and she (Iridessa) is home-bred. I get great pleasure out of Joseph beating me, great pleasure.
"I half expect it now. We know how tough it is and how hard they work (at the yard). It's marvellous - he could well put me into retirement before too long!"
