Leigha Miller ($5) had enjoyed a trip as comfy as they come when leading from the inside gate and had no issues when she was asked to dial up the tempo along the back straight, winning by five metres over Myra Dawn ($7, Mitch Turnbull) and Mister Haywood ($21, Blake Micallef).

It was the third win in the space of just five starts for the five-year-old Art Major mare, who had joined the Shane Sanderson stable after finishing her work for owner and previous trainer Gary Donaldson.

Wednesday's success made it two for two at Bathurst Paceway for Leigha Miller.

Winning trainer Sanderson said it was a textbook case of utilising the inside draw to your advantage.

"With the way the race was run she got away with some cheap sectional times early and that was always going to make it hard for the opposition once she got away with those times," he said.

"We've been happy with her. She hasn't been with us long but she's already built up a good record for us.

"I think she's capable of winning something like a mares race on a Saturday night, I think she's up to that standard. Hopefully she can have another couple of wins in the country areas before we try her at a metropolitan meeting."

Leigha Miller got to the lead unchallenged at the green light while the rest of the field took some time to sort themselves out.

Karinya Rocco got to the leader's outside but had that spot taken away by Rock Fisherman, who was caught wide with no cover and was forced to put in the extra effort to find the front.

Favourite Obi One ($2.40, Amanda Turnbull) was restrained early from the wide draw and bided his time at the back of the field.

Leigha Miller cruised along with quarters of 29.2 and 32.1 before Sanderson asked his mare to put the field under the pump.

Rock Fisherman and Myra Dawn, on the leader's back, came along for ride.

Sams Express was pulled to the outside by Phoebe Betts when a gap presented itself and the four horses gained a small break on the turn for home.

The favourite was left with far too much ground to make up, eventually finishing seventh, and no-one was mounting a challenge to the leader.

Leigha Miller won in a mile rate of 1:56.5, four tenths off her career best winning time she set a month ago at the same track.
