The brilliant mare Winx confirmed her place among the greats of Australian racing with a devastating victory in the Grade 1 William Hill Cox Plate at Moonee Valley this morning.

Ten horses lined up for this 1 ¼ mile contest, including the outstanding 2015 winner Winx, improved former Mark Johnston inmate Hartnell and the Andre Fabre trained Vadamos.

At the break it was Yankee Rose on the inside who got away best but Black Heart Bart went on from Hartnell and Awesome Rock, as the field headed away from the stands.

Vadamos and Mark Zahra were not content however and went into a five length lead from Black Heart Bart and Hartnell, with Winx closing.

Vadamos was soon a spent force however and Hartnell and WInx joined issue ahead of the home turn.

The filly, racing wide, went clear on the home turn and bounded emphatically clear by six lengths from Hartnell, Yankee Rose and Vadamos.

In a tactical race, Hugh Bowman remained calm throughout on the five year old daughter of Street Cry and the result was a stunning second win in the Plate.
