A recent barrier trial win has given Merlin Mustang's new trainer David Vandyke optimism ahead of the five-year-old's race return at Rosehill.

The winner of seven races for his previous trainers Mick Tubman and Michael Murphy, who is also a part-owner, Merlin Mustang has settled into life at his new Warwick Farm home.

He runs in Saturday's 1400m open handicap, a similar race to his most recent win in July last year.

Merlin Mustang, who has not raced since November, is also adept on wet ground which he is likely to encounter on Saturday.

"He has had a decent break and is certainly in a good place within himself at the moment," Vandyke said.

"I keep him away from the main track as much as possible and he is very relaxed.

"His barrier trial win was pleasing and I'm looking forward to getting him to the races and I know how well he goes on wet tracks.

"Tim Clark will ride him."

Merlin Mustang beat Sir John Hawkwood in the trial with the Craig Ritchie-trained former English horse among the 15 entries for the Rosehill race.

Vandyke is sending last-start Randwick winner Breakfast In Bed to Queensland where the mare will attempt to add black type to her record when she runs in the Listed Gai Waterhouse Classic (1350m) at Ipswich.

"I think it is a suitable race for her but I would love a good barrier for her," Vandyke said.

"She drew well last time and it made a big difference.

"Queensland's leading jockey Michael Cahill will ride her which is a plus."

While Breakfast In Bed heads north, Vandyke is pleased to see Arabian Gold back home after her Queensland Oaks second.

The filly injured herself during the race and the trainer feared the worst.

"Within ten minutes after the race, she couldn't put her foot on the ground," he said.

"It was very concerning and I feared the worst. But she came home yesterday and the foot has improved a lot.

"She can go out to the paddock for a rest now and hopefully she is back for the spring."
