Best In The World completed a double at the Curragh for Aidan O'Brien (also had a winner at Limerick) and Ryan Moore as she took the Listed Staffordstown Stud Stakes.

Second on her debut at Gowran last month the daughter of Galileo, who is a full-sister to Found, was well-fancied to get off the mark today.

Available at evens this morning she opened on-course at 10/11 before going off the clear 4/6 favourite.

Settled behind the leaders on the inner she was switched out with three furlongs to race and came with her challenge between horses with two furlongs to go.

She was ridden to lead inside the final furlong and kept on well in the closing stages to see off the late challenge of Dolce Strega by half a length.

The runner-up was returned at 16/1 under Billy Lee for Willie McCreery while Rayisa (7/1), who beat the winner at Gowran, was a further half a length back in third under Shane Foley for Mick Halford. Red Stars had no luck in running on the rail and she finished fifth.

Aidan O'Brien said afterwards: "She came on nicely from Gowran, and will make a lovely middle distance filly next year. Ryan said she feels like her sister (Found).

"You would have to be happy with that, and Ryan was kind to her."
