Sadler was the foundation trainer for Aquanita in 1998 but after leaving for several stints overseas and more recently Flemington in partnership with Troy Corstens, he re-joined Aquanita and moved to its training complex at Caulfield last Sunday.

On Saturday, smart mare Vain Queen made it two wins from two runners, after taking out the Dominant Handicap (1200 metres) at Moonee Valley following on from Gallant Harmony which won at Geelong last Tuesday.

"With the way the structure is there you just slot in, it's a bit like taking a horse to Adelaide or Sydney," Sadler said.

"My assistant trainer said to me that after a week it already feels like home and that's exactly how it feels."

Vain Queen had been beaten at her first two runs this campaign after winning her first four starts but returned to something like her best after a nice ride from Kayla Nisbet.

At those beaten runs, Vain Queen had raced too keenly but Nisbet was able to settle her out three wide just off the leaders.

After making her move as they cornered, Vain Queen ($5 fav) drew away to win comfortably from Nautical ($7.50), with Jolie Blonde ($15), which stuck to the fence, a long head away in third placing.

Sadler said he had been concerned with the way the track was racing but said in the end Nisbet had been able to position Vain Queen perfectly in the best going.

Before she resumed, Sadler had intended taking Vain Queen to Queensland but with the mare taking time to find her best form, he said he will probably keep her in Melbourne in an effort to pick up some black type.

The option in Queensland is the group 1 Tatts Tiara but Sadler said the listed Creswick Series Final over 1200 metres at Flemington on July 12 will probably be the better option for Vain Queen.

"We were thinking about Queensland but I'm not sure she's good enough for that, so we might look at a race up the straight at Flemington because she goes well there," Sadler said.

Changing stables was something of a theme for the day with Chris Waller, who is shifting into half of Anthony Freedman's old stables at Flemington, winning the Dominant Handicap (1600 metres) with consistent mare Mossmoney ($7).

Freedman, who will retain stables at Flemington while also shifting part of his team to Pinecliffe at Mornington, also had success at Moonee Valley with progressive two-year-old Nicoscene ($12) taking out the Slickpix Sprint.

Apprentice Jackie Beriman made the most of the opportunity to ride for Mick Price and, at her first outing for the Caulfield trainer followed instructions perfectly with a rails-hugging run, getting home Fast And Free ($15) in the final race.

"I told her to stick to the rails and I'd take the rap from the owners if he got beaten," Price said.

Price said Fast And Free, which was having his second run from a spell on Saturday, had plenty of improvement in him and he would attempt to qualify him for the final of the Winter Championship Series at Flemington on July 12.

Meanwhile, former long-standing Queensland race caller Wayne Wilson passed away in Brisbane on Friday after a long battle with cancer.
