The five-year-old mare was impressive with a two-length win when odds-on favourite at Canberra on Friday.

And the lure of the new Breeders and Owners Bonus Scheme (BOBS) platinum level cash provided every incentive for Superhorse manager Ross Williams and trainer Markwell, to chase a second success in a week.

"She pulled up really well, we're very happy with her," stable representative Nigil Monahan said. "It's taken a little while, but she was sent away to run in some country races and now looks really to move up in grade. There's plenty of improvement in her."

Racing NSW last year announced a major overhaul of the BOBS structure, implementing a platinum level worth $100,000, including $80,000 for the owner, $12,500 for the breeder, as well as $5000 for trainers and $2500 for the winning jockey.

Wednesday's meeting will be the first time the new incentive will be included at Kembla Grange.

There is also a gold level scheme worth $50,000, with Superhorse stablemate I Am Magnificent nosed out of a Class 3 victory at Tamworth by the Stirling Osland-trained Heaven's High. Jockey Rachel King has the tricky duty of pushing up from gate 10, while Chad Lever will be aboard Markwell's four-year-old gelding Hamogany, who races for the first time since July, having been in the top three in all of his five runs, including breaking his maiden at Kembla Grange.

Hamogany is listed at $8, behind Gerald Ryan's Peace of Mind, favourite at $4.20, with Heavenly Glory at $12.

Markwell was left to make a decision over the third of the Williams' runners in the Class 2, Philanthropist, who made the field after scratchings, but the 1500m trip looms as a test.

Philanthropist was also in a Benchmark 64 over 1300m on Wednesday, with star jockey Tommy Berry booked to tackle a wide barrier.

Markwell is also ready to unleash first starters Burning Need, a three-year-old filly - who won her only trial - in a 1200m Maiden and two-year-old filly Stolen Glance in a 1000m Maiden, as well as five-year-old gelding Pioneer, having his first runs since March 2018.

Kerry Parker also has a first starter in I Like Toucans, to be ridden by Jay Ford in the 1000m Maiden, following a Kembla Grange trial two weeks ago.

Meanwhile, Kembla Grange trainer Michael Tubman endured his first setback since returning to training, as raging favourite Wild Chap flopped at Goulburn on Tuesday.

The three-year-old gelding was sent out at $1.50 on the back of his stunning first-up four length win at Wagga, but after leading from the inside barrier into the straight, Wild Chap struggled to be five lengths off the Snowden-trained Invincible Dash at Goulburn over 1400m.

Tubman opened his 2020 account on January 9 with Wild Chap, his first runner since a four-month ban after EPO was found on his property, a substance he maintained having no knowledge of how it came to be there.

In October, trainer Mark Davies suspended for a year after a Racing NSW stewards hearing into the use of performance agent EPO this week. Davies was found guilty of possession and supply of a prohibited Erythropoiesis-stimulating agent.

Tubman's three-year-old gelding Delileo ($14) was impressive when a half-length second in a Goulburn 1400m Maiden on Tuesday.
