If unbeaten filly Appalachian Annie was racing anywhere but Flemington, trainer Vincent Malady would be feeling a little more confident.

The Geelong-based trainer makes one of his rare visits to Melbourne on Saturday with the unbeaten three-year-old who is the $4 favourite for the Euroa VCs Handicap (1000m).

But Malady said he would be happier if the race was run at Moonee Valley or Caulfield.

"I'm a bit worried about her up the straight," Malady said.

"I think her strength, being a little filly, would be around Moonee Valley or Caulfield where she can use her good gate speed and horses then have to finish over the top of her.

"Running up the straight at Flemington gives those horses more of a chance."

Malady said Appalachian Annie stood not much higher than 15 hands and she had overcome adversity in both her wins.

The filly started from the outside barrier on debut at Yarra Valley last October and again drew wide when first-up at Sandown earlier this month.

Malady said the Sandown win surprised him as she did it the tough way from the front on the long uphill straight.

Appalachian Annie's performance in her first shot at Saturday company will determine the rest of her campaign.

Malady has recently increased his numbers to 16 after restricting his team to around a dozen horses for most of his career.

"The only way to get more winners is to have more horses on the books, so I'll have a try at getting more numbers into the stable," he said.
