New Zealand Derby placegetter Platinum Invador will try to bounce back from a Rosehill disappointment when he lines up in Saturday’s Gr. 1 Australian Derby at Randwick.

After a powerful finish from last to run third in the Ellerslie classic on March 2, the Redwood gelding carried high expectations into his Sydney autumn campaign.

But he made a disappointing start in last Saturday’s Gr. 2 Tulloch Stakes at Rosehill, finishing eighth of the nine runners.

“He was really disappointing,” trainer Lisa Latta told www.theinformant.co.nz. “His work leading into it had been so good and we were expecting him to run well, but he was really battling. He might not have handled the track.

“But he’s come through it really well and hasn’t left an oat. We ran a blood test and everything looks fine, so we’re happy to carry on with him.”

Platinum Invador will be ridden on Saturday by Jonathan Riddell, whose relatively rare trips to Sydney in the past have included a Gr. 1 Rosehill Guineas win on Jimmy Choux in 2011 and the Gr. 3 South Pacific Classic at Randwick on the Latta-trained Platinum Kingdom in 2013.

Meanwhile, Latta will talk with connections in the coming days to determine whether New Zealand Oaks winner Sentimental Miss takes a shot at the Gr. 1 Australian Oaks on Saturday week.

“We’ll make a decision on that later this week,” she said.
