Earthquake clearly showed her superiority with an outstanding performance that saw her win the Blue Diamond Stakes at Caulfield.

She showed she is clearly among the very best two years old fillies we have seen out in a long while, and now a worthy Golden Slipper Stakes favourite.

The wide barrier was never a problem to her, she could have won the race from any gate, class carries you a long way, as it did with her.

When Rubick and Earthquake ran exactly the same time of 1.03.71in winning their respective Preludes, punters could not decide on a pronounced favourite.

Once the barrier draw was announced, with Rubick drawing more favourably than Earthquake, the colt was installed as favourite.

The flood of money came for Earthquake in the last 24 hours of betting, the market swayed in her favour.

Earthquake under Damian Browne winning the Blue Diamond

There are several factors about the win, not the least the ride of Damian Browne, he accepted the wide barrier and rode the filly accordingly, allowing her to settle and find her way into the race.

He had her in a winning position on the home turn, she put the race away within a couple of strides, they seldom win any easier than that.

Earthquake will now press on to the Golden Slipper Stakes in a bid to emulate the two state double as Sepoy did three years ago.

The win is another illustration of the success that Darley have had under trainer Peter Snowden, and his son Paul, they will move on after the Sydney Carnival to train in their own right at Randwick.

Both Peter and Paul Snowden have always been obliging with the media which has been most appreciated.
