Mike Moroney isn't pretending he can recapture past glories with the one-time star "miler" Wall Street.

But he is more than happy to try and coax another Group One victory out of an old horse who is as honest in his old age as he was talented in his prime.

"I wouldn't ask him to do anything that he wasn't comfortable with," Moroney said.

"He's been too good a horse."

Wall Street continues an interrupted spring campaign in Saturday's Group One Emirates Stakes (1600m), a race he won in 2010 when trained by New Zealander Jeff Lynds.

That was Wall Street's last victory, although he managed a fine fourth to Pinker Pinker in last year's Cox Plate.

Moroney is encouraged by the horse's last start third behind Fawkner in the Group Three TAB.com.au Stakes (1400m) which came after he had an injury enforced two-month break.

"He cut his leg in his first-up run in the Memsie Stakes, which was a shame because he'd been going really well," Moroney said.

"But his last start was one of the best he's put in for us, so I'm happy to give him his chance on Saturday.

"I'd thought of running him in the Eclipse Stakes in two weeks, it would have been easier for him, but he'd have got 60kg."

The Emirates at Flemington will mark the Group One debut of Fawkner, a stablemate of Melbourne Cup winner Green Moon and the winner of his past four starts.

Owner Lloyd Williams named the horse as his next big-race winner as he showed off his fourth Cup.

"He's been beating some good fields and he deserves his chance," Williams said.

"I'll run him on Saturday and then we'll probably give him a rest until the autumn."
