After jumping well, Dealmaker looked in danger of being caught three deep, so Kerrin McEvoy elected to do some work to sit outside of the leader Battle Plan.
Under strong riding, Dealmaker took the lead at the 300m but came under immediate attack by the Snitzel colt Morpheus who looked to get his head in front before the Chris Waller-trained colt fought back and was doing much the better in the closing stages to win by a long-neck.
The Kris Lees-trained Miss Earth (Stratum) was two and a quarter lengths back in third.
"I was a big fan of Dundeel, he was a tough racehorse and there are a lot of similarities there," Waller told Sky Racing.
"This horse will certainly be there as a three-year-old – I don't know if he will quite get to the heights of his dad but he's a chance that's for sure.
"I thought we were a length closer than where I anticipated he would be and I wondered if that might soften him up at the finish.
"I knew he would see out the distance strongly, but I worried he may have done too much in the mid stages. It was good to see him fight - he was off the canvas and he looks to have a bright staying future."
Built in the mould of his sire, Dealmaker (pictured as a yearling ) was a $160,000 purchase by Star Thoroughbreds / Chris Waller Racing from the Arrowfield draft at the 2017 Inglis Classic Yearling Sale.
