Jockey Steven King has given Mornington train Shane Nichols nothing but confidence that his Quezette Stakes winning filly I Am A Star will see out the mile of the Thousand Guineas 2016 this spring.

Over the weekend King made it three-from-three aboard the daughter of I Am Invincible, guiding I Am A Star to a narrow long-neck victory over Leotie and Athena Lass in Caulfield’s Group 3 Quezette Stakes (1100m).

It was the filly’s first-up win since taking out the Group 3 National Stakes (1200m) in Adelaide back in May and showed she had come through her winter spell well.

Nichols has the long-term Melbourne Spring Racing Carnival goal of the $500,000 Group 1 Schweppes Thousand Guineas (1600m) at Caulfield Racecourse on October 8 pencilled in for I Am A Star.

A winner of three of her four career starters, the three-year-old is yet to race over further than 1200m but Nichols has gain confidence from King’s reports that the filly will see out a strong mile.

“[King’s] adamant she’ll run a mile,” Nichols told Correct Weight on RSN on Sunday.

“If she’s drawn a gate, she’ll be able to possie up pretty close to the speed and quicken off the mark.

“He’s always been a big advocate for her in how she runs her races, she doesn’t get pulling, she doesn’t hesitate whether it’s in between runners, or outside runners.

“She leaves the gates clean – she’s a very compliant racehorse.”

Next-up Nichols is looking at a run at Moonee Valley on September 3 in the $120,000 Listed Atlantic Jewel Stakes (1200m).

He could still bypass the race however depending on the penalty weight I Am The Star receives from the handicapper for the set weights plus penalties sprint.

“Probably the Atlantic Jewel, but we’ve got to have a look and see how the penalties treat us,” he said.

“We copped 1.5kg above some of those fillies yesterday, and we’ll go to 2.5kg above them for a Listed race like the Atlantic Jewel.

“That was the initial thought, but I’ll refine that over the next couple of days.”

The other confirmed run for I Am A Star leading up to the Group 1 on Caulfield Guineas Day is the $200,000 Group 2 Schweppes Thousand Guineas Prelude (1400m) on September 24.

“We’ll go to the 1400m lead-up to the Thousand Guineas, and assess her from there,” Nichols said.

“I would imagine the way she’s been racing, and how she’s worked, I think she probably will run a mile.”

Current Thousand Guineas odds at Ladbrokes.com.au are led by the David Vandyke-trained Yankee Rose ($6), runner-up in the Golden Slipper and winner of Randwick’s Group 1 Inglis Sires’ (1400m) from April, while I Am A Star is at a quote of $17.

Yankee Rose is down to return first-up on September 10 at Rosehill Gardens in the $1 million Group 1 Golden Rose Stakes (1400m) and is equal $7 favourite for the three-year-olds’ classic with the John O’Shea-trained Lonhro colt Impending ($7).

Former Golden Rose Stakes favourite Capitalist, winner of last season’s Golden Slipper, has eased out to $8 in pre-field betting after his shock fourth as the beaten favourite in Saturday’s Group 3 San Domenico Stakes (1100m).
