Popular mare Single Gaze has retired after being withdrawn from the Sydney Cup due to a lower than usual red blood cell count.
Trained in Canberra by Nick Olive and ridden by Kathy O'Hara, the five-year-old finished second in last year's Caulfield Cup after finishing fourth in the Caulfield and Underwood Stakes during the spring.
She finished down the track in the Melbourne Cup but bounced back in the Autumn to finish runner-up in the CF Orr Stakes on her way to a fifth place in the Australian Cup.
The Sydney Cup was to be her last race but Olive notified stewards on Thursday that she would not be able to run after she failed to eat up on Wednesday, which led to the trainer taking a blood sample.
Single Gaze was also runner-up in last year's Brisbane Cup after she emerged in 2016 with a win in the group 1 Vinery Stud Stakes.
