Miracles Of Life is likely to go out on top with co-trainer Peter Snowden saying her win in the Robert Sangster Stakes is a perfect way to end her career.

The mare began her career in Adelaide and returned to Morphettville on Saturday to win the Group One fillies and mares sprint.

Formerly prepared by Dan Clarken who trained her to win the 2013 Blue Diamond Stakes, Miracles Of Life joined Peter and Paul Snowden in Sydney last year after Stonestreet Farm paid $900,000 for her at a broodmare sale.

"This was what her whole preparation was about. We identified the race early," Snowden told Sky Sports Radio.

"It is very fulfilling.

"She has no more to prove and I'll be suggesting she goes to stud now.

"She is a two-time Group One winner and going out in the best possible way you can go out - as a winner."

Snowden said he thought it would be impractical to extend her campaign to Brisbane, particularly with the prospect of wet winter tracks.

"We need to give her time to get over the trip and she doesn't love it in the float," he said.

"She doesn't move in the float but she lightens off.

"Brisbane to me is out of the question."

The Robert Sangster was the fourth Group One win this season for the father and son training team who left Sheikh Mohammed's Darley a year ago to set up their own operation.

Pride Of Dubai won the Blue Diamond Stakes and ATC Sires' Produce Stakes while Shooting To Win took out the Caulfield Guineas.

"I said to Paul when we started the Group Ones won't come like they did before so to think we have won four Group Ones in our first year is very satisfying," Snowden said.

"We started with a lot of young horses and we are still building up."
