Rubick and Earthquake ran identical times to win their respective Sportingbet Blue Diamond Preludes and the exciting two-year-olds now share identical odds for Saturday’s Group 1 Sportingbet Blue Diamond Stakes following the barrier draw at Caulfield this morning.

In a fascinating betting race, Rubick firmed from $3.20 into $3 at Sportingbet after drawing favourably in barrier 10, while Earthquake drifted from $2.90 out to $3 after drawing wide in barrier 15.

Chivalry, who drew barrier 3, shortened from $10 into $8.50 third favouritism within an hour of the conclusion of the draw after attracting a number of significant wagers including one bet of $3,000.

Nayeli is the only other runner under double figures, firming from $10 into $9 at Sportingbet after drawing gate 9.

“There’s nothing between the top two so I’m happy to leave it up to the punters to decide which of them will start favourite“, Sportingbet CEO Michael Sullivan said.

“Rubick has the better gate but if you were an Earthquake fan before the draw you certainly wouldn’t be jumping off her.”
