Mike Moroney admits it will be a tough ask for Wall Street to match it with All Too Hard on Saturday but he still believes there's a big race win left in the veteran galloper.

The eight-year-old kicks off his campaign in Saturday's Group One C F Orr Stakes (1400m) at Caulfield, as does Cox Plate runner-up All Too Hard who is favourite.

Moroney says Wall Street appears in good order for his return following a summer campaign in Perth.

Wall Street finished eighth in the Group One Railway Stakes in late November before being scratched at the barriers prior to the Group One Kingston Town Stakes at Ascot.

"He didn't lose a lot of fitness in his time off and he'll kick off in this on Saturday and probably head towards the Australian Cup with one run in between," Moroney said.

"Obviously Hawkes' horse (All Too Hard) at weight-for-age is going to be pretty hard to beat."

Wall Street was third to the Team Hawkes-trained All Too Hard in a Flemington jump-out over 800m last Friday.

Winner of the Caulfield Guineas in the spring, All Too Hard impressed in the hitout which was run in smart time.

He is out to become the first three-year-old to win the Orr since Yell in 2003.

Wall Street hasn't won since taking out the Emirates Stakes in 2010 when trained by Jeff Lynds.

But Moroney believes he can still make an impact, evidenced by his luckless fifth in the Emirates last spring.

"He looks well and he didn't start racing until he was four so hopefully he has still got a season left in him," Moroney said.

Another of Moroney's Group One performers, Glass Harmonium, is preparing for his autumn return after having a bone chip removed from a fetlock.

"He might have a jump-out on Friday," Moroney said.

"He seems good and he'll go first-up into the 1800 metre race (the Peter Young Stakes) and then on to the Australian Cup."

Moroney will be represented in four stakes races at Caulfield with Octavia in the Listed Kevin Hayes Stakes (1200m), Bonnie Mac in the Group Three Bellmaine Stakes (1200m) and Zabisco in the Group Three Carlyon Cup (1600m).
