Full Hand is poised to make up for a disappointing city debut, according to trainer Brian Cox.

The well-bred four-year-old runs in the Alternate Railway Handicap (1600m) at Moonee Valley on Saturday.

His only Melbourne start came towards the end of a winter campaign when he finished down the course on a rain-affected track at Flemington.

But Full Hand won at Wodonga last start and Cox believes now is his time, despite an obvious jump in class.

"He went fantastic at Wodonga but we're going from playing Ovens and Murray League football to AFL football," Cox said.

"But the way he won was fantastic. There will be a bit of pace on and it's a different pattern of racing, but I can't fault the horse."

Full Hand will also move up in trip which carries a query, but Cox hopes other factors will overcome that issue.

"The 1600 (metres) just concerns me a touch. We've just got to hold him up and hope he can see the journey out.

"I think Moonee Valley will suit him. He's a big-striding horse, he's a Bel Esprit horse and I can't ask for any more," he said.

He also takes encouragement from the fact that Full Hand's second at Seymour last month came behind the Robbie Griffiths-trained It is Written, which won at Moonee Valley at its next start.

Cox also has Sumakaray and Chinzia set for a decent showing on Saturday.

Sumakaray, a three-year-old, lines up in the Chandler Macleod Handicap (1000m) after winning at Wodonga before a cautionary scratching at Moonee Valley two weeks ago.

"She had a little infection, a bit of cellulitis which blew up, We could have run her but we just didn't want to chance her," Cox said.

Saturday will be a serious test for the filly, according to Cox.

"We've got to place them right. We took her to Flemington last month - her only city start - but down the straight she got lost.

"She's drawn 12 tomorrow which is our only real concern, we just hope she doesn't get trapped too wide," he said.

He also feels his four-year-old mare Chinzia will be competitive in the Mitchelton Wines Handicap (1200m).

"Every time we've raised the bar with her she's held her head high," Cox said. "We're going to raise it again and we just hope she can be right there."
