Sea Siren wasted little time transferring her three-year-old form to her four-year-old year with victory in tonight's $750,000 Sportingbet Manikato Stakes (1200m) at Moonee Valley.

The classy Sydney mare registered Group 1 number three at her first start as a four-year-old when she proved too good in the feature event on the opening night of the inaugural Sportingbet Cox Plate Carnival.

The daughter of Fastnet Rock followed wins in the BTC Cup and Doomben 10,000 at the highest level during May to make it six wins from nine starts and bring a big smile to the face of proud trainer John O'Shea.

"She doesn't make too many mistakes and she put in a really good performance tonight," the Randwick trainer said.

"Right from the time she stepped back in the stable this time we felt she had made good improvement and it has just been a matter of getting her fit gradually and having her right tonight.

"It was probably a testament to her performance because those horses that travelled around her in the run finished well back in the field so she was probably entitled with her condition to give out late."

Sea Siren joined Dane Ripper, Sunline and Miss Andretti among the mares to have won the Manikato Stakes in the past 15 years with her victory.

After jumping well for Hall of Fame jockey Jim Cassidy, Sea Siren was put in the gun spot one horse back on the outside before being produced rounding the home bend.

The $5.50 chance powered to the front inside the 200m and kicked a length clear before holding on to score by a neck for another resuming runner, the Peter Snowden-trained Mental ($14), who rocketed home along the fence after having trouble obtaining a run until well into the straight.

Third, 2-1/4 lengths away, was We're Gonna Rock ($10), marginally in advance of Hallowell Belle ($14). Buffering, the $2.60 favourite, led and was pressured by Satin Shoes, but was beaten soon after straightening and finished sixth, 3-1/4 lengths from Sea Siren.

Cassidy was delighted with the way Sea Siren travelled in the run and knew a long way out it was going to take a good horse to beat her.

"I knew the way I was travelling on the corner they would have to be good to come from behind me and beat me," he said.

"She won the way I thought she would, with a bit up her hand."

Sea Siren will get her shot at back-to-back Group 1 wins in the $1 million Patinack Farm Classic (1200m) up the famous Flemington 'straight six' on 10 November.
