Smokin' Romans was beaten favourite in the Caulfield Cup the start after his Turnbull win and finished seventh in that year's Melbourne Cup but his only start at Flemington this year prior to the Queen Elizabeth Stakes realised a second placing to Horrifying back in July.
Ben Melham was able to do as he pleased aboard the son of Ghibellines in the Queen Elizabeth Stakes, leading at a pedestrian tempo before giving a good kick early in the straight.
The $13 chance scored by half-a-length from Star Vega ($6.50), who made good ground from the back, with Berkeley Square ($6) 3-3/4 lengths away third.
"He's been a little bit out of form this horse, but he's a good galloper on his day," Melham said.
"He just loved that – finding a rhythm in front today – and he's returned to his best.
"You have to have ability to win a Group One and you can never discount horses in this yard. He's a master, Ciaron, and I just sat on top and pointed."
The Queen Elizabeth Stakes was the first Australian start for Chris Waller-trained import Kinesiology ($3.80 fav), who travelled behind Smokin' Romans but seemingly did not appreciate the slow tempo and failed to run on in the straight, finishing a 7-1/4-length fifth.
