Puzzle was a well-named filly when she arrived at Heath Conners' stable.

She had shown talent in barrier trials in Sydney but had not lived up to that promise in three starts for her previous trainer, Heath's father Clarry Conners.

The two-year-old's owners sent her to the younger Conners whose smaller operation at Geelong allows him to spend more time learning about his horses.

"She was running in really hard races but doing everything wrong," Heath Conners said.

"The owners were quite happy to send her down to me and the first thing I had to do was figure her out."

Conners found Puzzle's biggest problem was a lack of concentration in her races, which prevented her from doing her best.

Puzzle previously raced in a lugging bit and a tongue tie but Conners went for winkers and ear muffs for her return to racing at Sale on May 29.

The changes worked perfectly and Puzzle showed her abundant talent with a two-length win, convincing Conners to send the Shamardal filly straight to town to tackle Wednesday's Polytrack Plate (1200m) at Sandown.

Nicoscene ran third at Sale and buoyed Conners's confidence in Puzzle's chances at Sandown when he won at Moonee Valley last Saturday.

"Nicoscene winning at Moonee Valley certainly helped to assess the strength of her Sale form," Conners said.

"She has to be a really good chance on Wednesday with that form line."

Conners says Puzzle, the first foal to race out of the Group Two winner Court, could develop into a spring prospect if she continues her improvement at Sandown.

Luke Nolen will ride Puzzle and her stablemate Belcrest Lady, who runs in the Betty McDowell Elsternwick Plate, while Dean Yendall will partner Esprit's Choice for Conners in the Bushnell Outdoor Products Handicap at Sandown.

"The stable is going well and this always is our best time of the year so all three of our runners have good chances," Conners said.

"We target the off-season period with our team. We aren't the biggest stable so we place them as best we can and hopefully get the results."
