Trainer Adam Durrant is confident This’ll Testya can return to her imposing best at Ascot on Saturday.

The Testa Rossa mare was touted as the next star of Perth racing after winning her opening two races in explosive fashion.

Following a dominant Bunbury debut last November, This’ll Testya backed it up at Ascot a fortnight later and gave her rivals a galloping lesson.

In a brilliant display of sustained speed, the four-year-old commanded the pace and sprinted clear to win by a whopping 6 ¾ length margin over City Circle.

But the bubble burst in shock fashion at her next start when she faded to fifth after racing fiercely outside of the leader.

The surprising defeat as the raging favourite came just seven days after she was scratched from a 1200m event following a float accident on the way to the track.

Although her reputation took a big hit, Durrant believes it was trainer error that contributed to This’ll Testya’s first defeat and he expects her to bounce back.

“I’m going to put my hand up and I think it was my fault,” Durrant said on Tabradio.

“I should have put her in the paddock straight away after that float mishap.

“You get disappointed when that happens and you want to redeem yourself.

“I probably made an error in judgement taking her to the races so quickly.

“Hindsight is a wonderful thing, but I’ll put my hand for that one.”

This’ll Testa will tackle the Julie & Mike’s Birthday Handicap (1100m) from barrier one on Saturday.

It’s the ideal draw for Chris Parnham, replacing William Pike, who has commitments in Melbourne.

“She is just a running filly that needs to be left to control things herself, rather than us controlling her.

“But she’s in good order and her work has been spot on.

‘She is the same horse we took to the races with those two good victories.

“Hopefully we see the best of her Saturday.”

Meanwhile Durrant says he can see no reason why Star Exhibit can’t win the Listed Detonator Stakes (1800m) in successive years.

The eight-year-old won the Group 2 Lee Steere Stakes (1400m) over Gatting when first-up last November.

The Statue Of Liberty gelding ended his campaign with a fourth placing to Mississippi Delta in the Perth Cup (2400m) in January.

Durrant said Star Exhibit had worked well since running a close second to Lonsdale Lady in an 1100m barrier trial.

“They’ll know he is out there on Saturday,” Durrant said.

“He’s work has been good and he has done really well.”

Peter Hall will ride Star Exhibit in the Detonator Stakes.

This’ll Testya and Star Exhibit are $1.60 and $1.75 respectively with Tabtouch.
