Ambitious spring carnival goals are on the agenda for Missy Longstocking after her winning comeback at Eagle Farm on Saturday.

Ridden by apprentice Aidan Holt, Missy Longstocking, the $2.70 favourite, edged past Sinister Prince ($15) in the final stages of the Powerade Handicap (1000m) to win by three-quarters of a length.

Trainer Liam Birchley has a couple of options to choose from for Missy Longstocking's next start at Caulfield on October 12.

"There's a Group Three fillies and mares race or the Blue Sapphire which is worth $100,000 more but has no black type so we'll see what's entered for those races and try and pick the right one for her to run in," he said.

If Missy Longstocking performs up to Birchley's expectations at Caulfield he is keen to run her in the Group One Coolmore Stud Stakes (1200m) at Flemington on Victoria Derby Day, November 1.

Birchley admitted he was unsure how Missy Longstocking would measure up at her first test against older rivals at Eagle Farm.

"She was lining up against some specialist 1000-metre horses but I'm very happy with the result," he said.

"She was probably getting a bit tired towards the end but Aidan rode a very mature race and didn't overuse her until he had to go for her at the finish."

Holt, who has worked hard to keep his riding weight under control, was so confident of Missy Longstocking's prospects, he rode at 54kg for the first time in six months.

"She showed she's a class above the rest and I think she'll make the grade when she goes to Melbourne," he said.

"Towards the end of the race she was getting a bit tired and she's not a big fan of the stick so I went back to hands and heels and she did the rest."

A Melbourne trip is also being considered by trainer Kelly Doughty for Black Cash after his first-up win in the Channel Seven Handicap (1200m).

Doughty is toying with the idea of starting Black Cash in a race restricted to grey horses at Flemington on VRC Oaks day, November 7.
