Talented sprinting mare Viddora posted a career best performance when winning the Group III SAJC RN Irwin Stakes at Morphettville on Saturday beating Illustrious Lad and I Am a Gypsy to give I Am Invincible a rare graded trifecta. Trained on the track by Lloyd Kennewell, Viddora was narrowly beaten into second place at her last three starts so was well overdue for a win. She settled just behind the leaders for Chris Parnham and forged clear to win the 1100 metre sprint by a length. A $40,000 Magic Millions Adelaide purchase for her trainer from the Riva Ridge draft, Viddora has won six of 19 starts earning over $550,000 in prizemoney. Bred by Riva Ridge, Viddora is the first winner for good metropolitan winner Snow Flight, a daughter of blue-blooded Zabeel stallion Colombia. I Am Invincible has had a benchmark year both in the sale ring and on the racetrack and as a result his service fee has been raised to $110,000 for 2017.
