After breaking through for a Group One win in the William Reid Stakes, Silent Sedition is favourite to snare a second at the elite level.

Silent Sedition gave Caulfield trainer Andrew Noblet his first Group One victory in the William Reid at Moonee Valley last Friday week when she dropped in distance from 1500m to 1200m.

The race was a stepping stone to Saturday's Group One Coolmore Legacy (Queen Of The Turf) Stakes (1600m) at Randwick.

At her only other Sydney start, Silent Sedition was a close second in the Group One Coolmore Classic (1500m) on March 11 when collared late by Heavens Above.

"I thought she would run really well in the William Reid but to win it was a huge bonus," Noblet said.

"I put her in there mainly because it was going to be a month between runs on a rain-affected track and she was feeling that well.

"I thought she could run in the first three and to go there and win it was just massive.

"After the frustrations of the start before when I thought she should have won the Coolmore Classic, to come out and do that was just really pleasing."

Noblet said Silent Sedition had trained on well and would gallop in the clockwise direction at Caulfield on Tuesday before travelling to Sydney on Thursday night.

Craig Williams reunites with the mare on Saturday after Katelyn Mallyon was aboard in the William Reid, which was also the jockey's first Group One win.

Williams has ridden Silent Sedition in nine of her 16 starts and has been booked for Saturday's race since after the Coolmore Classic in which she was ridden by Hong Kong-based Sam Clipperton.

Noblet is hoping there won't be much more rain in Sydney this week for Silent Sedition who is at $4.60 ahead of Foxplay ($6) and Dixie Blossoms and Heavens Above at $8.

Silent Sedition is untried on anything worse than a soft track which she handled in the Coolmore Classic.

"She's feeling very, very well so hopefully that translates on race day," Noblet said.

"But she doesn't know how to run badly.

"We had her in the Doncaster and decided to bypass that and go straight here. That's what we aimed her at and hopefully we get the job done."
