Simon Miller won’t come out a declare Iowa a sure thing in Sunday’s Boulder Cup (2116m), but the Ascot trainer is a big believer in his Galileo gelding.

Former West Australian mare Amelia’s Jewel will debut for a new stable at Randwick.

After initial hesitancy from connections, Iowa has rubber-stamped his incursion into WA racing and ominously hovers over the upcoming Kalgoorlie carnival after another successful performance at Belmont on Saturday.

Amelia’s Jewel will take her first step towards a race return in a Warwick Farm barrier trial.

After a winless winter campaign, the veteran gelding’s career isn’t finished yet and he’ll return to defend his Idyllic Prince Stakes (1300m) crown on August 24.
