O'Brien's team top the Pretty Polly stakes at the Curragh
Aidan O'Brien is responsible for five of the 14 remaining fillies in the mix for Sunday's Oxigen Environmental Pretty Polly Stakes at the Curragh.
The master of Ballydoyle has saddled two previous winners of the 10-furlong Group One in Peeping Fawn (2007) and Misty For Me (2011) and this year's quintet is headed by 2012 Epsom Oaks heroine Was.
O'Brien also has last week's Ribblesdale Stakes runner-up Just Pretending, Magical Dream, Say and Moth engaged, although the latter has been declared to run at Naas on Wednesday evening.
John Gosden's The Fugue was interestingly among the entries having run an excellent third on her seasonal reappearance in the Prince of Wales's Stakes at Royal Ascot.
However, Curragh general manager Paul Hensey revealed on Twitter she would not be lining up this weekend.
He said: "The Fugue will not run in the Oxigen Pretty Polly Stakes. Her inclusion on the runner sheets is an administrative error."
Among the leading contenders are Dermot Weld's Princess Highway, Tommy Stack's Alive Alive Oh and Kevin Prendergast's La Collina.
Prendergast said: "She ran a good race over a mile the last day at the Curragh and hopefully she's come on for that.
"I think she's more of a 10-furlong filly now and I'm hoping for a big run from her."
