A stayer New Zealand trainer Roger James has earmarked as a potential star of the future will make a hit-and-run visit to chase Sydney prize money on Saturday.

A regular visitor to Australia for the country's major carnivals, James has decided to try a rare off-season trip with Enjay who will line up in the TAB Quaddie Handicap (2590m) at Randwick.

James had intended to spell Enjay due to the wet tracks in New Zealand but the enticement of a distance race and the chance to more than triple the mare's bank balance tempted him to cross the Tasman.

"The alternative was to turn her out but then I spotted this race and she looks well placed," James said.

"If she can win, it might set her up for something later in the year."

A daughter of noted sire of stayers High Chaparral, Enjay has won two of her 11 starts in her homeland, the most recent a 2100-metre victory two weeks ago.

Saturday will be the first time she is extended beyond that distance but James has no doubt she will relish the stamina test.

The four-year-old will be spelled after she races at Randwick and James doesn't envisage her being seasoned enough to take to Melbourne in the spring.

But he does believe Enjay is showing the hallmarks of a classy stayer and he rates her a potential Cups horse in 2015 and beyond.

"I've trained a few out of the family and they are better at five and six," he said.

"They're a late-maturing breed and she's no different."

Jay Ford has picked up the mount on Enjay at Randwick and she is on the second line of betting at $5.50 behind Tonopah.

James also reported BMW and Ranvet Stakes winner Silent Achiever was back in work and likely to kick off her spring assault in the Memsie Stakes at Caulfield on August 30.

He confirmed Nash Rawiller was keen to stick with her in a campaign aimed at the Melbourne Cup.
