John O'Shea is keen to target the Group One Stradbroke Handicap with Sea Siren but first hopes to land the Surround Stakes with the exciting filly.

Sea Siren handled the step up to stakes company with a narrow victory over Group One winner Streama in the Group Two Light Fingers Stakes (1200m) two weeks ago.

Streama is favoured in betting to turn the tables on Sea Siren in the Group Two Surround (1400m) at Warwick Farm on Saturday but O'Shea can't fault his charge.

"She's going well and I'm really happy with her," O'Shea said.

"We were pretty confident she would run very well in the Light Fingers, she's a good filly that has made good progression very early in her career.

"Hopefully she'll be competitive again on Saturday."

Sea Siren's four starts have all been on good tracks but Warwick Farm was rated a heavy (10) on Thursday which is an unknown for O'Shea.

"She had a good gallop on the Kenso (Kensington track at Randwick) on Tuesday and looked OK," O'Shea said.

"And I think as a rule the Fastnet Rocks are OK on it. I would be surprised if she didn't at least get through it on Saturday."

Sea Siren was confidently ridden by Jim Cassidy first-up and O'Shea believes the champion jockey is once again the key to getting the best out of her in the Surround.

Streama is the $1.80 favourite on TAB Sportsbet ahead of Sea Siren at $4.80.

O'Shea admitted the Guy Walter-trained Streama was capable of turning the tables given the small margin between the pair last time out but is hoping for the same result.

"I think luck in running is paramount and capacity to handle the ground is going to be relevant as well," O'Shea said.

"Jimmy will try to be relatively positive and this is the sort of filly that can handle that."

O'Shea said he had the option of progressing to either the Phar Lap Stakes or Coolmore Classic over 1500m on March 24 with Sea Siren after Saturday, but the trainer has the Group One Stradbroke (1400m) during the winter in Brisbane in mind.

O'Shea won the Stradbroke with three-year-old filly Private Steer in 2003.

"I do want to run her in the Stradbroke, that's her main goal," O'Shea said.
