The Group 1 racing continues at Caulfield this Saturday with the running of the Underwood Stakes and 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 Waterhouse/Bott-trained Sir Delius 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. It's Pink Ribbon Cup day at the Gold Coast.
