JOCKEY Daniel Moor celebrated his 37th birthday on Saturday with his first Australian Group 1 win, piloting the Trent Busuttin and Natalie Young-trained Sierra Sue to victory in the Sir Rupert Clarke Stakes over seven furlongs at Caulfield.

The Darci Brahma mare had been ridden by Johnny Allen in her past three starts which included wins in the Midura Cup and the Group 2 Lawrence Stakes but, with 52.5kg in the Group 1 handicap, Moor made the most of his opportunity.
