McCall holds a place in racing’s history books that no trainer can take from her when she became the first woman to train a Stradbroke Handicap winner with River Lad in 2014.
Her history making feat was equalled by Australia’s first lady of racing Gai Waterhouse, who along with co-trainer Adrian Bott, also won Queensland’s richest sprint with Alligator Blood three years ago.
A daughter of Rich Enuff, Tiger Shark has already won at Stakes level when she bowled over a slick field in the Listed Mick Dittman Plate at Eagle Farm in April last year.
Tiger Shark has won twice since her Mick Dittman victory and will be chasing her seventh win at her 21st start.
She also finished just behind the placegetters in Stakes races in the Listed Keith Noud at Doomben in November and Listed Bribie Handicap at Eagle Farm and last month.
