A change in her training routine has helped Bengal Cat return to form and has brought a Group One race into focus for the filly.

Trainer John Sadler has always had a healthy opinion of Bengal Cat but until Saturday's Sandown meeting she had only one win as a late-season juvenile from 11 starts.

After she finished out of the placings at Moonee Valley in the Group Three Alexandra Stakes late last month, Sadler decided to change a few things in Bengal Cat's training with the desired result.

Ridden by Sadler's son Tom in Saturday's 1600m-race, Bengal Cat raced near the speed and went on to score by three lengths over Bendigo Guineas winner Silent Sedition.

"Her last start she got locked away on the fence at Moonee Valley when we thought she'd run really well," Sadler said.

"A couple of days later I was bringing her home from the pool and she was up on her hind legs and I thought 'maybe you haven't tried too hard'.

"So she just had to do a bit of schooling and then she went off to the bull ring for two or three sharp sessions there. Sometimes it does the trick and sometimes it doesn't.

"It's obviously done the trick with her."

Sadler said he would now look at the Group One Australasian Oaks (2000m) at Morphettville next month.

"I'm not certain that she'll get the mile and a quarter. I know she'll run a strong 1800 metres, but I thought there was quite a bit of depth in Saturday's race," Sadler said.

"I don't think it would be foolish to take her over and give her a try at a Group One."
