The Cox Plate beckons for outstanding filly Samantha Miss but for now trainer Kris Lees is happy to savour the history-making victory in the Group One Flight Stakes at Randwick.

Samantha Miss and Angst (1993) are the only two horses to win all four legs of the Princess Series - the Silver Shadow Stakes (1200m), Furious Stakes (1400m), Tea Rose Stakes (1500m) and the 1600-metre feature.

"The Cox Plate is still in our plans but I'd rather not take the gloss off what she has achieved here," Lees said.

"We'll start thinking about the Cox Plate next week.

"She's an absolute champion in her own right and deserves her place in history."

Ridden by Hugh Bowman, Samantha Miss was taken out the back early where she stayed on the fence until near the 800 metres before being taken three wide and presented for a barnstorming finish.

The Gai Waterhouse-trained Maybe I led at the 400 metres but it was soon evident that Samantha Miss had the race in her keeping and she quickly put paid to her rivals, going on to score by 2-1/2 lengths over Portillo with Kimillsy three-quarters of a length away third.

"I was a little concerned when Hughie got her over on the fence after a furlong (200m) but he popped her out and she relaxed beautifully and she stayed right out of trouble," Lees said.

"She's got that great turn of foot and when they straightened she was always going to be hard to hold out."

Bowman was delighted with the performance but warned Australia's weight-for-age championship, the Cox Plate (2040), would be a massive test for the filly.

"She proved that she's a champion today," Bowman said.

"Physically she's ready for the Cox Plate but mentally you just don't know until you have a crack at it.

"It's a huge step for her but she is very special and these special ones are capable of anything."

Darley Australia's Trevor Lobb said Portillo would head to Melbourne for Wednesday week's Group One Thousand Guineas (1600m) at Caulfield.

"That's always been the plan and there's no need to change it," Lobb said.

Trainer Kim Waugh said Kimillsy would also target the Thousand Guineas.

The Cox Plate is at Moonee Valley on October 25.
