Jockey Craig Newitt believes Miss Andretti has what it takes to complete a famous sprint double at Royal Ascot on Saturday.
The 22-year-old partnered the Australian speedster to a record-breaking triumph in the King’s Stand Stakes on Tuesday.
And he expects another “big performance” from Lee Freedman’s mare as she goes for the second leg, the Group One Golden Jubilee Stakes.
Newitt said: “The word I use to describe all this is ’privilege’ – I am so lucky and so honoured to ride such a brilliant mare.
“At this stage, she looks well and I’m sure she’ll be at her top for Saturday.
“She’s such a gutsy mare and she has this incredible toughness about her.
“The quick back-up shouldn’t be a problem and I’m expecting another big performance,” Newitt told www.theage.com.au.
Miss Andretti’s rivals include compatriots Magnus and Takeover Target, third and fourth respectively in the King’s Stand.
Magnus’ trainer Peter Moody said: “I thought he was a bit fresh before the King’s Stand and the run will do him a world of good.
“Potentially, the horse could stay here for the July Cup at Newmarket or the Nunthorpe at York – both races would suit him.”
Takeover Target was third in the Golden Jubilee last year after winning the King’s Stand.
His trainer Joe Janiak said: “Everything is good. The run didn’t knock him around too much. He is having an easy week.
“The six furlongs will suit him better.
“They just went too quick for him early on the other day. Now he is older, he has lost a little bit of that early sprint so the extra distance will suit him.
“I wouldn’t be worried about ground and the 10 draw is fine.”
