This week's Winning Post will be available online here from 3pm AEST Thursday.

The Group 1 racing continues at Caulfield this Saturday with the running of the Underwood Stakes and the return to September of the Sir Rupert Clarke Stakes.

In the Underwood some smart middle-distance horses will be looking to add a major to the mantelpiece at the Heath, with the Chris Waller-trained Buckaroo looking to go back-to-back.

The undercard at Caulfield includes the Caulfield Guineas Prelude for the three-year-olds, the Jim Moloney and the Naturalism.

In Sydney the action is at Randwick for the $1 million 7 Stakes for the weight-for-age milers, The Shorts for the sprinters, the Tea Rose for the fillies, the Bill Ritchie and the Kingston Town.

Our form coverage kicks off on Friday with a full form guide for Ballarat, plus fields, colours and tips for the other Friday TAB meetings.

The metro racing this Saturday is at Caulfield in Melbourne, Randwick in Sydney, Morphettville in SA, Eagle Farm in Brisbane and Belmont in Perth.

Winning Post carries full-colour liftout guides for all those meetings plus bet365 Echuca (Vic/SA edition), Newcastle (NSW edition) and Gold Coast (Qld edition), as well as fields, tips, ratings and/or colours for other TAB Saturday cards.
