Peter Hall will replace William Pike on star filly Delicacy in Saturday’s $400,000 Group 1 Australasian Oaks (2000m) at Morphettville.
Pike, who had been named, dislocated his left shoulder in the barriers at yesterday’s Lark Hill trials and will be sidelined for at least three weeks.
“I was out of luck in a barrier incident,” Pike said from hospital.
“It’s the same shoulder I’ve injured before. I definitely can’t take the Adelaide mount on Saturday.”
Owner Bob Peters booked the in-form Hall after confirming Pike was unavailable.
Pike’s racing manager Dale Verhagen said the injury was a bitter blow.
“William will meet doctors (today) to discuss the shoulder dislocation,” Verhagen said.
“The best-case scenario is a three-week absence. It could be longer.”
Hall rode Delicacy to win the Ascot 1000 Guineas (1800m) and Natasha Stakes (2200m) before Pike piloted the filly in her WA Oaks (2400m) and WATC Derby (2400m) victories.
“Peter Hall is going to Adelaide to ride Delicacy,” Peters said. “He knows the filly well.
“Today, she had her first work-out since arriving there. This was the gallop which decided whether we accepted for the Oaks.
“Reports were good and all seems on target for her to start on Saturday.”
Delicacy drew barrier 11 and was quoted at $6.50 with the TAB behind Victorian filly Fontein Ruby ($3.50 favourite) and Fenway ($4.60).
Perth mare Magnifisio drew gate four for Saturday’s other Group 1 feature in Adelaide, the $400,000 Robert Sangster Stakes (1200m).
The TAB had the Jim Taylor-trained mare at $12 yesterday.
Vain Queen was the $5.50 favourite in an open race.
Meanwhile, brilliant sprinter Black Heart Bart, a Lark Hill trial winner yesterday, leaves for South Australia today.
Trainer Vaughn Sigley confirmed a start in the Group 1 $500,000 Goodwood (1200m) at Morphettville on May 16.
“Glenn Smith retains the ride and will be there to work him in the week leading up to the Goodwood,” Sigley said.
Black Heart Bart clocked 55.18sec. yesterday and beat stablemate Dawn Approach by a neck. Sigley said Takahide Ikenushi would again ride Dawn Approach when he clashed with Barakey in Sunday’s $125,000 Northam Toyota Stakes (1100m) at Northam.
A second swab from the Sharon Taylor-trained Ignition has tested positive to cobalt.
