When asked if the David Hayes-trained new sensation has any chinks in his armour, Williams delivers a sure and certain 'no'.
"If you're winning the international races up there and you're coming back to the domestic horses, it is going to be very easy for Ka Ying Rising," he said.
So, with that sorted, the immediate attention of Magic Million races under lights on Friday, Melbourne's current leading jockey teams up with Brisbane's leading trainer, Tony Gollan, to ride $6.50 chance La Bella Boom in the Magic Millions 2YO Classic (1200m).
"Tony said that she is one of the toughest two-year-olds he has trained and she eats up everything and is so sound," Williams said.
"The extra six days was favourable for her but it wasn't necessary either.
"As a rider, you're always guided by the trainer and their team around them.
"If she turns up like she did at Sunshine Coast, I was impressed and the confidence that brings to young horses is always an advantage."
Craig also rides Nettuno and Skirt The Law for Gollan's stable.
After the Gold Coast, an early flight to Melbourne sees Williams with eight rides at Flemington before his Saturday night flight to Hong Kong.
To New Zealand later in the week, he will partner Captured By Love for Te Akau Racing in the Group 1 Railway Stakes (1600m) next Saturday.
Captured By Love is rated a $6 chance and is third favourite for the Ellerslie feature.
