Beautiful Citi thunders home© Photo Healy Racing
Beautiful Citi gave Joseph O'Brien and across-the-card treble with an authoritative display in the mares' bumper at Clonmel.
She made good headway on the outer to get on terms in the final half mile and eased to the front approaching the home bend.
The Fame And Glory filly was shaken up by Tom Hamilton as they hit the two pole.
She was well in command in the final furlong and drew clear by seven and a half lengths at 4/1. Vic's Little Miss took second at 25/1 with Villa Moura half a length back in third at 13/2.
Joseph O'Brien, at the Curragh, said: "She had a lovely run first-time out and we thought she would come forward from that.
"We thought she would run well. I haven't see the race yet but I'm delighted she has won."
He saddled Dom Carlos (11/1) and Remmy D (7/2) to win at Headquarters.
