Surgeonor trains a small team at Ardmore, primarily for owner Peter Walker and his wife Sherin, who race Showoroses.
Walker was a part-owner of Fully Funded, who gave Surgeonor her biggest moment in racing when he won the 2017 Listed Counties Bowl (1100m) at Pukekohe.
"I've had a few other stakes placings but never won or placed in a group race," Surgeonor said.
"It's a group three race and she's a filly. It would be nice even to place to get black-type to her name," Surgeonor said.
"She ran well last week and pulled up well so we thought we'd have a go."
Bred by the Walkers out of their group three-winning and group one-placed mare Rodrigo Rose, Showoroses finished second on debut as a two-year-old last season before an unplaced run in stakes company at Te Rapa.
She returned at three with a narrow maiden win at Avondale and a gritty Rating 65 win at Ellerslie last week.
"It was an amazing win. She broke 1:10 for 1200m and she's done it all herself out in front. She's coped amazingly," Surgeoner said.
"She's always given me the feeling she was above average. Everything she's been doing up to now has been easy for her. It all comes naturally. She's a happy horse."
