The silks of the Annus Mirabillis Syndicate were carried to their first success as Donnacha O'Brien doubled his score at Dundalk with his father Aidan's Stone Mountain landing the spoils in the Money Back 2nd At Titanbet.co.uk Handicap.

Donnacha had won on Pat Shanahan's Split The Atom earlier but here he got Stone Mountain through a gap between horses around a furlong out.

Favourite Spruce Meadows had looked a likely scorer at that stage but the O'Brien owned and bred 5/1 winner showed a good attitude and level of ability to come out on top by three parts of a length.

Aidan O'Brien also supplied the third home, the Mick Hussey-partnered Ineffable who ended up two and a half lengths further back.

Head of the successful syndicate, Donal O'Mahony said: "The syndicate is made up of some people from the financial services and some who aren't. What binds us all is that we are racing enthusiasts.

"We're delighted to be involved with Aidan. We have half a dozen horses and that's our first winner so we're all thrilled."
