Chris Waller will set his sights on the Princess Series with Tutta La Vita after she added to his brilliant juvenile season with a gritty, albeit narrow victory at Rosehill.

Having made a clean sweep of Sydney’s two-year-old triple crown with Shinzo and Militarize, Waller has unearthed a host of other promising youngsters throughout the term, Tutta La Vita among them.

While the daughter of The Autumn Sun gave punters who took the $1.85 some anxious moments, Kerrin Mcevoy was able to lift her over the line to nail Canadian Ruler ($12) by a neck in Saturday’s The Agency Real Estate Handicap (1400m).

Waller said the decision to ride the filly closer might have dulled her finishing sprint, but he felt it would make her a more furnished racehorse next preparation.

“It wasn’t pretty for a short-priced favourite,” Waller admitted.

“But Kerrin took bad luck out of the equation and having her further forward probably took away a little from her finishing sprint.

“She got the job done. She is a two-year-old winner and can go out and come back to be aimed at the good three-year-old fillies’ races.”

Waller trained The Autumn Sun, who won five Group 1 races from just nine starts and McEvoy was in the saddle for four of them.

He expects the stallion’s progeny to improve with time and distance and as he did with stablemate Zougotcha last year, Waller is looking to pick and choose his way through the four-race Princess Series with Tutta La Vita.

“The series is great, but it is a long path for the girls,” Waller said.

“We have had success by missing some of them. Zougotcha won three out of three (and missed the Furious Stakes).”

Tutta La Vita gave Waller his 20th juvenile winner this season in what has been his most successful term with his young horses.

His tally is just 10 less than Godolphin’s James Cummings and eight behind Tulloch Lodge partners Gai Waterhouse and Adrian Bott, who are renowned for having their horses up and running early.
