Duncan said Dzsenifer had every chance in last month’s Silk Stocking on her home track and will appreciate a softer surface at Doomben following recent rain.
“She doesn’t like hard tracks any more and is more at home on softer tracks,” he said.
“She’s a chance in this race but she’s not as good as she once was.
“Her last run was very good and she wasn’t beaten far and her run just petered out near the line.
“We’re looking at retiring her soon and if she doesn’t win or run well then this could be her last run.”
Duncan also has booked Collett to partner stable mate Goldsborough in the Listed Chief De Beers over 1110 metres.
Goldsborough has drawn barrier four and is coming off a first-up run when he dead-heated with the Stuart Kendrick-trained La Amigo in the Bat Out Of Hell over 850 metres at the Sunshine Coast on May 6.
“He’s going well and his win in the Bat Out Of Hell was his first run since he finished fifth in the Magic Millions Sprint in January,” Duncan said.
“There are no big plans with him. We’ll keep looking for suitable races and dodge the good ones during the carnival.”
