Peter Moody-trained Star Scream remains only a rough chance of contesting next month's Queensland Derby despite his powerhouse performance to win at Caulfield.

The three-year-old produced a stunning form reversal after being easily beaten at Flemington to snatch long neck win over Fieldmaster and Cabeza in Saturday's PDF Food Services Handicap (2000m).

Stablemate Garozzo, who is also nominated for the Queensland Derby, finished fourth.

Moody's leading Queensland Derby candidates Tee Emar and Arvan are already in Brisbane.

The Caulfield trainer said Star Scream and Garozzo were still under consideration for the classic but would only start if he thought they would be competitive.

"I am happy to go if we think they can run well but we're not going to make up the numbers," Moody said.

"We have three weeks to assess it."

Star Scream has won three of his nine starts but Moody doubts he is seasoned enough for a Derby.

"He is quite immature and everything says he will be better at four and five," Moody said.

Two starts ago Arvan beat Star Scream in a photo finish at Sandown and ridden by apprentice Jack Hill on Saturday he was given little hope of winning at $20 after his last start 10th to Kutchinsky at Flemington.

Hill was under similar instructions to last start when he was told to ride for luck from back in the field and this time it paid off.

"It is good to see the horse hit the line well," Moody said.

"Last start he peeled out and got knocked sideways but it came off this time."

Moody said Star Scream, a son of Testa Rossa, would win his share of races but he believed at this stage of his career he would be better placed staying in Melbourne for one more run at Flemington in the Rod Johnson Handicap (2000m) on June 12, the same day as the Queensland Derby at Eagle Farm.

He said Garozzo, who was one of the favourites on Saturday at $4.40, was paying the penalty for his consistency with big weights.

This campaign he has raced five times for two wins and two minor placings.

"He is doing a good job but he is still learning," Moody said.
