Silwana (8/1) demolished her 15 rivals in Leopardstown's mile and six 'Pettingo' handicap.

Dermot Weld's filly was a close third in this valuable handicap last year but made no mistake in this renewal.

The four-year-old held a prominent position under Pat Smullen before being pushed into second at the three pole. She then had the leader Roheryn in her sights approaching the home turn.

She raced up on the outside of Roheryn and took up a narrow lead entering the home straight.

She opened up with a furlong and a half to go and readily asserted. She moved clear in the final furlong and powered away to put four and three quarter lengths on Western Boy (9/1).

Roheryn (16/1) came home third, a further length and three parts back. Alton Bay at 33/1 completed the placings. Renneti the 4/1 favourite, finished 14th.

"She's progressed this year and battled well when winning on Derby Day at the Curragh," Dermot Weld said.

"She ran a very good race behind Fields Of Athenry. She's a good filly and is improving all the time. She's been a model of consistency.

"It was a good renewal of the race. She had to be at her best to win it and she was. She always appreciates a little ease in the ground.

"She's stakes placed and hopefully is capable of winning a stakes race. The Loughbrown Stakes at the Curragh is definitely possible for her."
