O’Brien dominates Moyglare entry
Last year's renewal of the Moyglare Stud Stakes produced the first three home in this season's 1000 Guineas at Newmarket and Aidan O'Brien saddles four very promising fillies at the Curragh on Sunday.
Hydrangea and Rhododendron take each other on again
His team is headed by Rhododendron, who claimed the Debutante Stakes last time at the expense of reopposing stablemate Hydrangea.
The unbeaten Promise To Be True and Royal Ascot winner Brave Anna complete the Ballydoyle challenge.
O'Brien's son Joseph fields Intricately on the back of his fleeting return to the saddle in the Leger Legends race at Doncaster on Wednesday.
The Mick Halford-trained Rehana beat Rhododendron comfortably at this track back in June, but the tables were turned in the Debutante, with Rehana only fourth.
Halford said: "We have a bit to find on her last run, but she worked very well the other day and we're very happy with her at home.
"I think good ground is the key to her, so any rain that falls won't be to her advantage. If the ground were to deteriorate too much we mightn't run her, but we'll see what happens."
The seven-strong field is completed by a fascinating newcomer in the form of Dawn Of A New Era.
Jim Bolger's filly is pitched in at the deep end for her debut, but is bred to be top-class as a full-sister to 2000 Guineas hero Dawn Approach and Group Two winner Herald The Dawn.
