His trainer says Hallowed Crown is the best three-year-old colt in the country and his jockey is now a believer.

James Cummings and Hugh Bowman were searching for superlatives after Hallowed Crown's tenacious win in Saturday's Group One Randwick Guineas (1600m).

The colt's senior trainer Bart Cummings was watching from home but his grandson was on hand for Hallowed Crown's second Group One win over a quality field.

Despite his Hobartville Stakes victory over Sweynesse and Shooting To Win, Hallowed Crown was not the punters' elect.

Shooting To Win was sent out at $2.50 and led the field at a seemingly comfortable pace with Hallowed Crown ($2.90) tracking him.

At the business end of the race, Hallowed Crown moved up a level with Sweynesse ($3.90) looming. But he held off his rival by three-quarters of a length with Shooting To Win a short head third after finding little inside the 100m.

"Bart has been saying to just get off the fence and although I told him it wasn't easy from barrier one, he said it was," Cummings said.

"Hallowed Crown is the best three-year-old in the country.

"We will take on the Japanese horses now in the George Ryder and then go to the Doncaster.

"He has proven how well he goes at the Randwick mile now."

Two visiting Japanese horses - World Ace and Real Impact - are scheduled to run in both the weight-for-age George Ryder and the Doncaster.

Bowman, who won the Golden Rose on Hallowed Crown in the spring, said the pair had formed a more meaningful partnership this time around.

"Before the Golden Rose I didn't have much to do with him but I have been with him all the way along this campaign," he said.

"He just does enough to win.

"He is very laid back and relaxed. Maybe that's why we get on so well together.

"I thought I had Shooting To Win covered and I was more worried about Sweynesse.

"The thing about him is you don't know what's there. He is right up with the best three-year-olds I have ridden and the world's his oyster.

"I'm a believer."

Shooting To Win's co-trainer Peter Snowden said his plans for the colt remained the same - to take on Hallowed Crown again in the George Ryder.

"He was just a bit keen. He is much better off when he can find a sit," Snowden said.

"With everything behind him he just wanted to do a bit much too early."
