Sir William Bruce had all the answers to the Cabinteely Handicap in Leopardstown to give Aidan O'Brien and Ryan Moore a treble on the card.

He sat third in the mile and half assignment as Sassified took the field along closely followed by Supposedtobe

Sassified had burnt off Supposedtobe turning for home but Sir William Bruce picked up the baton in second.

He whittled away the gap and collared the leader over a furlong out. He was soon ridden to go and win his race and held on as the closing Snowy Owl came at him late.

The 11/2 chance won by half a length from 20/1 Snowy Owl. Britzka (15/2 from 10/1) also finished well for third, beaten a length by the winner.

O'Brien said: “He’d a better run than it looked in Naas as he had a very bad draw and hit a number of ridges down the back.

“He’s a grand horse and anything from a mile and a quarter to a mile and a half would suit him.

Ideally, he’d prefer a more strongly run race but Ryan gave him a good ride and had him in a good position.

“We might go back for another handicap and give him time to progress.”

Scot Sir William Bruce (1630 - 1710) was considered to be the foremost architect of his generation.
