In the absence of unbeaten star Turk Warrior, trainer Adam Trinder had three of the five runners and punters landed on the right one.

Miss Tuppence was backed from $4.20 to $2.70 before getting up in the last stride to beat stablemate and favourite Outbound by a short half head.

Winning jockey Troy Baker said Trinder and owner Wayne Roser had given him a lot of confidence before the race.

"They told me this filly has an explosive turn of foot and, if I could get her to settle, she'd run over the top of them," Baker said.

"And she did."

Roser said it was a pleasing result heading towards the $100,000 3YO Cup in a fortnight.

"I thought she was very impressive - she hit the line well after a fantastic ride by Troy," the owner said.

"She can get a bit on her toes from time to time which is why we like to ride her from behind.

"I used to think 1100m might be it, but it looks like she'll get 1200m and maybe a bit further."

Baker settled Miss Tuppence in third place as Outbound bowled along freely in front ahead of Coeur De Lyon.

Miss Tuppence went inside the second horse at the top of the straight to give chase and made up two lengths on Outbound in the last 100m.

Coeur De Lyon was 2-3/4 lengths away third.

Adam Trinder and Wayne Roser are also likely to be represented in the 3YO Cup by Majestic Diamond who made it two wins from two starts in the Class 1 Handicap.

"We've always rated her in the top three seeds of our three-year-olds so she'll step out against the big boys next start," the trainer said.

"We thought we'd take the easier option with her first-up and go for the Class 1 rather than the 3YO Handicap but it turned out to be a deep, strong race."

Majestic Diamond worked to the early lead and, although headed mid-race, Erica Byrne Burke held the rail and the Trust In A Gust filly was back in front on the home turn.

She kicked clear at the top of the straight and went on to score by 1-1/2 lengths.

"She came here off the back of only one trial so was probably half a run short," Trinder said.

"We expect her to go on with it but I'm dubious about whether she'll get the distance of the three-year-old classics later on.

"She might even find herself in Melbourne at some stage."

Trinder said Majestic Diamond had always shown good talent.

"But we've had to be gentle with her because she's had a lot of shin-soreness issues," the trainer said.

Belle Cadeau emulated her talented half brother Le Cadeau when she made a winning debut in the Vale Rosanne Roles Maiden.

Le Cadeau also won his first start at Mowbray, almost two years ago to the day.

It was a good result for punters as the Barry Campbell-trained filly was backed from $9.50 to $4.80.

Campbell said the daughter of Tasmanian-bred group 1 winner Palentino had been a really slow maturer.

"She was thick as a brick," the trainer said. "So we've given her four trials before taking her to the races.

"Her two trials at Longford were good but the two at Spreyton were poor so she might not go on the synthetic."

Le Cadeau also won later in the night.

The heavily-backed Chosen Eagle got punters away to a good start won the opening race but not before giving them some anxious moments.

The Adam Trinder-trained three-year-old was caught three wide just behind the leaders and it took him the length of the straight to overhaul rank outsider Her Thoughts.

Chosen Eagle opened anywhere between $3.50 and $2.90 with the corporates and just kept shortening to start $1.65.

Trinder said the Alpine Eagle gelding was still "a work in progress" and was still mentally immature.

"He's just starting to get an idea of what is required of him," the trainer said.

"He travelled well tonight but wobbled a bit at the top of the straight before knuckling down to his task.

"So he should continue to improve."

Trinder said Chosen Eagle didn't cope with life at his on-course stables at Spreyton.

"So we now train him from the farm and just keep him happy," he said.

After well-backed winners in the first three races, punters came back to earth with thud when $26 chance Good Luck Bob won the 1400m Maiden.

It was a nice result for well-known owner Bob Milne, who also bred the Unusual Suspect gelding, as he picked up $20,000 in Tasbred bonuses on top of the $13,125 stake.

Good Luck Bob had his only previous start almost a year ago when Spreyton trainer Liandra Gray said he was too immature, mentally and physically.

"He had a long time out and he's grown up a lot," Gray said.

"His trials have been much better this time in and, although I'm probably surprised he won, I expected him to go pretty well."

Good Luck Bob, ridden by Siggy Carr, made the most of a soft run behind the leader Belmista and ran down that horse in the closing stages to score by a half neck.

Favourite Bell Ringer Boy finished a luckless third.
