For a couple of hours, second emergency Kermadec was safely in the Doncaster Mile field and close to being favourite.

But with Saturday's Randwick meeting postponed until Monday because of the weather, trainer Chris Waller is again playing a waiting game with scratchings reinstated.

The Waller-trained Moriarty was withdrawn early on Saturday morning because of the extremely heavy track while Godolphin's It's Somewhat came out with a temperature.

That gave Kermadec and first reserve Sweynesse, also from Godolphin, starts in the $3 million race.

But after a second track inpsection on Saturday morning the meeting was rescheduled.

If the surface improves with Sunday's fine weather, Waller said Moriarty could take his place while John O'Shea, trainer of It's Somewhat, said the horse's temperature was back to normal.

"We'll see how it is in the next 24 hours," O'Shea said.

"I want to do what is right by both horses."

Both Sweynesse and Kermadec are also entered for the Carbine Club Stakes against their own age group.

Waller is also represented by Sacred Falls and Royal Descent who ran one-two a year ago, leading in an historic first four for the trainer.

"They are both well and the wet track suits them," he said.

"Kermadec has never been on it while Moriarty has been placed on a soft track but not heavy."

The situation has had a flow-on effect for other trainers with Joe Pride unsure if he has a rider for Destiny's Kiss.

If Sweynesse gets a start, Sam Clipperton will switch from Destiny's Kiss.

When It's Somewhat came out on Saturday, Pride snapped up his jockey Craig Williams.

"I'm going to the races not knowing who will ride him," Pride said.

"But I am going with a horse I know can defy his odds ($51). He is a freak on wet tracks and it will still be heavy even if the weather holds."

Pride also has another dilemma with Destiny's Kiss who he had planned to back up into the Sydney Cup.

"It leaves just five days instead of seven so that is looking less likely now," he said.

Hallowed Crown remains the $5 Doncaster favourite ahead of Kermadec and Pornichet at $7 and Royal Descent at $7.50.

Royal Descent's wet record has attracted punters and she accounts for 20 per cent of bets taken by the TAB since the market re-opened.

Kermadec finished third in the Group Two Hobartville Stakes behind Hallowed Crown and Sweynesse before an unlucky fourth in the Australian Guineas at Flemington.

He returned home for an eye-catching third in the Group One weight-for-age George Ryder Stakes won by Japanese visitor Real Impact who has drifted to $15 with concerns over his wet track credentials.
