Evergreen jockey Jim Cassidy wrapped up a winning double for trainer John O’Shea with Sea Siren taking out the Group 2 $175,000 Patinack Farm Light Fingers Stakes (1200m) at Warwick Farm on Saturday.

Cassidy had early in the day scored on Warwick Farm for O’Shea in the Group 2 $175,000 NSW Thoroughbred Breeders Classic (1200m) and showed that he has lost none of his skill and determination with a top class ride on Sea Siren.

The Fastnet Rock filly was stepping up sharply in class but with a solid barrier trial under her belt Cassidy was certain he had a fit horse underneath him.

“She is a very, very good filly,” Cassidy said.

“We knew she had to be up in the first three and we thought she was up to them.

“The way she worked on Tuesday we came here very confident,” Cassidy said.

All pre race plans had to be thrown out the window when predicted leader Karuta Queen missed the start again and Cassidy was quick to react and pushed Sea Siren up outside the leader.

Sea Siren hit the lead in the straight and held off the late challenge of the short priced favourite Streama who was held up in traffic at a crucial stage.

O’Shea’s foreman Bryce Heyes agreed with Cassidy’s thoughts that Sea Siren was an above average filly.

“She was dynamite when she worked on Tuesday,” he said.

“It was a massive step in grade for her but we were very, very confident.”

Queanbeyan trainer Neville Layt will be giving Karuta Queen a short break after her below average performance to finish ninth, seven lengths from the winner after missing the start for the second time in her last two starts.

Layt took Karuta Queen to Melbourne for the Rubiton Stakes last week when she ran an unlucky fourth behind Eagle Falls after blowing the start and then saddled her up a week later in the Light Fingers.

“She just raced flat and that’s not like her,” Layt said.

“We’ll give her three or four weeks off and freshen her up.”
