Sydney Cup winner Polarisation will most likely be back for the Melbourne spring, according to Charlie Appleby's assistant James Ferguson, trying to do a rare double.

Godolphin trainer Appleby added another big race win down under to his resume on Saturday - and his first Australian Group 1 - as Polarisation held out Who Shot Thebarman and Big Duke to win the $2 million dollar, two-mile race.

“(Polarisation) ran a personal best yesterday, he got into a dogfight and came out on top,” said Ferguson, who added he’s now likely to try and emulate the likes of Carbine (1890) and Makybe Diva (2004), who won both the Sydney and Melbourne Cups in the same calendar year.

"He's definitely deserved his spot [on the plane back]," Ferguson told RSN 927's Correct Weight on Sunday.

"He's proven that he suits Australian racing more than he suits English racing.

"The way he won, you'd almost have to bring him back for a Melbourne Cup.

"But he's had two hard races in a row, so we'll take him home, and we won't worry about a future just yet.

"We'll see how he is when he gets back, and if he's fit and well and giving us all the right signs when it comes to choosing our Melbourne Cup team, then we'll definitely bring him back."

Appleby's Australian strike-rate is extraordinary. The English trainer has had runners in 10 individual races down under, and won six of them.

And in two of the races he didn't win, Appleby saw Scottish finish second in the Caulfield Cup, and Qewy fourth in the Melbourne Cup.

Had the original running of the Sydney Cup stood, Appleby had first (Polarisation) and third (Penglai Pavilion) past the post, and while Penglai Pavilion couldn't repeat his performance on Saturday when seventh, Ferguson said circumstances were against him.

"I wasn't disappointed, because he tried so hard and ran so well the time before, and that was his day," Ferguson added.

"And if things had gone right the day before, I think he'd have run better than third.

"But he needs everything to go right for him. He needs an easy lead. He needs not to be wound up so quickly.

"Kerrin [McEvoy] did a great job on him yesterday, it was everyone around him, it was the bigger field, it was Lasqueti Spirit going out in front, it was the whole race, Penglai Pavilion needs it to go right and he got knocked around a bit."

Running twice over two miles in a fortnight period is not usual practice in Australia, but it'd be even less likely to be an acceptable route in the UK where horses generally have bigger spaces between races.

Ferguson said as a result, freshening Polarisation up in 14 days was a task.

"We had them ready on the day [April 8]," he said.

"Polarisation went and won the first time... you have to take these situations as they come, that's racing for you, and there were more important things at hand. We respected the decision that happened.

"It was very important to freshen things up. We came over to run him fresh. Everyone was asking if he's OK to run first-up two miles, but that was our plan.

"It was very important to let these horses get back to enjoying themselves. They did everything right for us. We were very, very easy on them in the first week.

"Then we stepped their work up that last week going into the Cup. I didn't do any fast work with them at all.

"They were thriving, [but] you can't really tell until you get to the races.

"But we had never been in that situation. At home, you'd never run two miles two weeks after running a two-mile race, so it was a bit of an experiment."
