The no-nonsense attitude of Dupe `em has fuelled jockey Craig Newitt's belief that the youngster can make a seamless transition to Saturday grade at Flemington.

The Chris Waller-trained Dupe `em impressed on debut at Sandown when he finished strongly from back in the field to win over 900m.

He steps up to 1200m in the Hong Kong Jockey Club Handicap and Newitt sees no reason why he won't handle it.

"He's a really nice horse and is just one of those two-year-olds that everything he does, he just pleases you," Newitt said.

"He hasn't done a thing wrong to date and I can't see that changing on Saturday.

"I think he will be very hard to beat."

Newitt's only query going into Dupe `em's debut on July 2 was whether he would find the 900m too short.

He managed to win but Newitt expects the galloper to be in his comfort zone over the extra distance.

"Especially down the straight," he said.

"The first half of the race will probably be run pretty leisurely and it will just give him a chance to really travel underneath me.

"You saw how good his acceleration was the other day after being off the bit for so long, so I would expect him to be very strong again late on Saturday."

Dupe `em, a $5 chance in early betting, is one of three horses Newitt is booked to ride for premier Sydney trainer Chris Waller along with Fulgur and Amovatio.

Fulgur, an acceptor in Melbourne and Sydney, is expected to run in the Ascot Racecourse Handicap (2000m) at Flemington for which he is an early favourite.

Newitt's book also includes the Ciaron Maher-trained Seven Falls who resumes in the Bruce Gadsden Hcp (1000m).

Newitt rode the horse to a seven-length win on debut at Mornington on wet ground but was unavailable to ride the three-year-old at his second start when he finished fourth at Moonee Valley in December.

"I gave him a jumpout last week and he was pretty impressive in his trial without letting him off the bridle," Newitt said.

"He is a horse that really appreciates soft ground. The 1000 metres first-up looks ideal. It looks a pretty tough race - there's a couple of handy ones in it - but I think he's above average himself."
