The five-year-old will contest a 1400 metre benchmark 88 at Randwick in what his trainer hopes will be the first run of a successful campaign.

With a talented horse on his hands and the coronavirus pandemic likely to limit the number of international raiders arriving on our shores, Parker is thinking big.

While he recognises his goals are lofty, the veteran trainer is buoyed by fourth-place finishes in the listed Canterbury Cup and Group 3 Manion Cup in the autumn.

"He'll be nominated for the Melbourne Cup," Parker said. "That's just a wing and a prayer, but we'll aim high.

"We'll focus on heading through the Sydney carnival and hopefully picking up some good results. We're aiming for the Metropolitan and St Leger, so he's got to be competitive in those races to warrant going down.

"Getting horses across the border could prove challenging, but with less international horses it could open up more opportunities for the Australian horses."

Parker sent Think It Over to the paddock hoping to see a bigger and more mature horse return to his care.

That is what transpired, with the trainer pleased to see his gelding had filled out during the time off.

Having won a trial on Randwick's polytrack last week, Parker is confident his charge can now mix it with Sydney's top stayers.

"He's come back a stronger horse. He came a long way last prep, he started off in a class two and ended up running around in a Group 2.

"I'd watch him in the enclosure and he looked like a teenager among men. Now he won't look out of place at all. He's mentally and physically stronger."

Think It Over is the headline act in a talented crop of horses moving through Parker's stable.

Recent addition Cyber Intervention enjoyed city success throughout the winter, while Tampering impressed in winning three-straight races at country and provincial level earlier this year.

The four-year-old returned to the track with a solid trial at Kembla Grange on Thursday, a heat won in impressive fashion by Gwenda Markwell's promising four-year-old Electric Girl.

Also back in action is Kembla Classic runner Sorridere, with Parker nominating the mare for a 1400m class one in Nowra on Sunday.

"We just had a throw at a few of those three-year-old races," Parker said. "She was bred to stay, but 2000m was probably too far at that stage.

"This prep we'll try to win one race, then knock off another race and take it race by race. We have no set plans, we'll just try and keep building and winning races."
