Brosnan is already a Group 1 placegetter and co-trainer Gerald Ryan has reason to believe the colt can continue to build on that record this spring.
Third behind Sheeza Belter in the JJ Atkins Stakes, the three-year-old will resume in the Ming Dynasty Quality (1400m) at Rosehill on Saturday.
A $15 chance in pre-post markets, he is on the sixth line of betting but Ryan can make a genuine case for Brosnan featuring in the finish.
“It wouldn’t surprise me. We’ve always had a good opinion of him and he was always going to be better as a three-year-old,” Ryan said.
“He is bred on the same cross as (Ryan’s multiple Group 1 winner) Trapeze Artist, by Snitzel out of a Domesday mare.
“If he goes well enough on Saturday, he’d go to the Golden Rose, then he’d go to the Caulfield Guineas and that would probably be it for him.
“He had a pretty tough two-year-old autumn in the sense he did a bit of travel as well as racing.”
Brosnan had just under a month off after his Brisbane winter carnival campaign and carries residual fitness into Saturday’s assignment.
Ryan’s only caveat to the horse’s chances are track conditions with Brosnan producing his best results on firmer surfaces while the two times he finished outside the top four were on heavy tracks.
“I wouldn’t like to see too much rain. His three runs on good tracks were good, his three on heavy tracks were so-so,” he said.
“Although they were heavy 10s he was running on too.”
Brosnan will be joined in the Ming Dynasty by stablemate Williamsburg, who under the steadier of 59kg and an outside draw will be ridden quietly and produced late.
He is on a Spring Champion Stakes path and will be better suited under set weights conditions and once he steps up in journey.
“I doubt whether he could beat these horses over 1300 metres with that weight,” Ryan said.
“But after this race he goes three weeks into the Dulcify (Quality) and that’s set weights. Then he goes to the Gloaming which is set weights again and then the Champion Stakes which is set weights again.”
