Jaqen H'Ghar provided the O'Brien's with another family success when justifying favouritism in the Leopardstown Club Members Nursery Handicap.

The 15/8 favourite opened his account at Gowran Park on Tuesday, and followed up here over a mile under a mandatory 5lb penalty.

The home-bred son of Fastnet Rock, trained by Aidan O'Brien for his wife Annemarie and ridden by their son Donnacha, led just inside the furlong pole.

He edged a bit left when striking the front but quickened well to score by a length and three quarters from Don't Quit. Fire Tree and Super Bowl took third and fourth in a bunch finish for the minor placings.

The stewards held an enquiry into possible interference but found that any was accidental and the placings remained unaltered.
