Champion mare Winx will have only two rivals when she lines up in the Group One Caulfield Stakes.

Chasing her 12th straight win and an eighth at Group One level, Winx will be opposed by the Darren Weir-trained Black Heart Bart and Lindsay Park’s He Or She on Saturday.

Black Heart Bart is chasing a third Group One win of the season while Lindsay Park has had a change of heart electing to start He Or She on Saturday instead of Sunday’s Cranbourne Cup.
