Unbeaten filly Stroak recorded slow time when she won at Doomben on Saturday but trainer Bryan Guy and jockey Michael Cahill defended her performance.

Despite racing on a good track, Stroak ran the 1200m in a moderate 1min12.44sec, 4.56secs outside the course record.

Guy said the slow time wasn't a true indication of her ability.

"They didn't roll along early and she just put her head on her chest until it was time to get serious," Guy said.

"They ran the last two furlongs in 22 seconds and not many two-year-old fillies win with 58kg on their back."

Stroak will have her next start in the Group Three BJ McLachlan Stakes (1200m) at Doomben on December 28 which will be her final outing before the $2 million Magic Millions Classic (1200m) at the Gold Coast on January 11.

Cahill said Stroak will be better suited when she can settle off the speed in a high-pressure race.

"In a Magic Millions I'd imagine she'll be sixth, seventh or eighth in the run and if she can find a bit more natural improvement there's no reason why she can't be competitive in a race like that," he said.

Rocky King won't have another lead-up race before the Magic Millions Sprint after he led throughout to win the Madame Wu Handicap (1020m).

"I'd rather he went five weeks without another run then start him in the Bat Out Of Hell and have to back him up the following Saturday in the Sprint," trainer Tom Bourke said.
