The battle for Horse of the Year honours started to heat up last month, with the modern record of females looking likely to continue.
With just a few months of the season left to run, Miss Finland and Miss Andretti have established themselves as the front runners.
Miss Andretti notched up Group 1 win number four for the season in the Newmarket Handicap.
It completed a unique quartet for the mare, becoming the first horse to win the Manikato, Lightning, Australia Stakes and Newmarket in the one season.
She also lumped the biggest winning weight a mare has carried (56kg) for 18 years in the Newmarket.
The Sean Buckley owned mare has gone from strength to strength under the care of Lee Freedman this season.
She is now the holder of the Moonee Valley 1000m and 1200m track records, alson with the Caulfield 1200m mark, which had stood for more than a decade. Miss Finalnd became just the second filly (after Triscay) to win the Australian Guineas.
She also joined Flying Spur as the only Golden Slipper winners to take the Guineas.
Miss Finland is making a habit of setting new benchmarks and Group 1 win number five followed two weeks later when she took the Arrowfield Stud Stakes.
With four Group 1 wins each to the end of March, these two have put themselves in a position to join the likes of Makybe Diva, Sunline, Let’s Elope and Research as filly/mare winners of Australian racing’s top honour.
