Asking continued Ana O'Brien's flying start to the season when getting off the mark in the mile maiden at Dundalk.

The Ballydoyle filly was sent off 6/4 favourite on her return to action having been runner-up on her final start at Leopardstown last season.

The daughter of Zoffany tracked the leaders before launching her challenge a furlong and a half out.

She wore down front-runner Sir Danilo inside the final furlong to gain a length victory.

The winner's stable-mate Music Box was a big eye-catcher as she stayed on strongly close home on her debut, just denied for second by a nose.

“She travelled well and picked up well. She loved the surface, and is a filly that will like fast ground. I'd say she will get a bit further,” said the winning rider.

Ana O'Brien had partnered a double for her father Aidan on the opening day of the Flat season at Naas.
