Multiple Group 1 winner Streama has been scratched from the Group 1 2012 Emirates Stakes (1600m) at Flemington on Saturday.
The Guy Walter-trained mare was found to have heat in her leg meaning she will end her spring campaign without a win in the top grade.
The Stratum mare experienced mixed results throughout her campaign, with her won win from four starts coming in terrific style in the Group 2 Tristarc Stakes.
The withdrawal of Streama sees a jockey change with leading Sydney hoop Hugh Bowman now taking the ride on Rolling Pin.
Rolling Pin is rated a $61 chance to score his first Group 1 win in what will be his second start in Melbourne this spring.
The Gwenda Markwell-trained gelding is at the end of a long campaign that began in August with a third-place finish in the Group 3 Missile Stakes at Warwick Farm.
He then produced two back-field finishes before turning his spring around with wins in both the Group 3 Cameron Handicap and the Group 2 Shannon Stakes.
The son of Pins was strong when third in the Group 1 Epsom Handicap before travelling to Melbourne and finishing seventh in the Yellowglen Stakes.
Despite his big price, Rolling Pin is not without a chance in the Emirates and long-priced runners have experienced plenty of success in the $1 million event in recent years.
Currently heading the market for the Emirates is Lloyd Williams-owned gelding Fawkner is at $4.80 to record a fifth consecutive win this weekend.
Queensland gelding Solzhenitsyn is second in the betting at $6.50 where he will chase his second Group 1 win after taking out the Toorak Handicap earlier this month.
