Riccarton trainer Andrew Carston made the bold decision to bypass the Karaka Million 2YO (1200m) last week with Miss Federer in favour of the Gr.3 Woburn Farm 2YO Classic (1200m) at New Plymouth on Saturday and his charge duly delivered for her connections.
Miss Federer was pushed forward by jockey Lisa Allpress and was caught in a speed duel early with Amazing Team and Folk Dress, which resulted in the Swiss Ace filly being posted three-wide the trip.
She was able to account for the two early aggressors in the straight and had to draw on all her reserves to holdout fast-finishing race favourite Hasstobegood to win by a long neck, with 3-1/2 lengths back to Last Light.
"It's unbelievable. That was just unreal," Carston said. "She is very tough, it was a very hard run.
"She has always been a filly who has never really showed us anything at home, but raceday is a different story.
