Mark Newnham, keeping the Tulloch Lodge winners flowing in the absence of holidaying trainer Gai Waterhouse, is counting on the stable's former No.1 jockey Nash Rawiller to help continue the run at Randwick on Friday.

Now riding freelance, Rawiller has the mount on Driefontein when the mare has an important lead-up run to the Magic Millions carnival in the Flying Handicap (1000m) on the Kensington track.

A winner of almost $1.7 million in stakes, Driefontein has been asked to carry 61kg, 3kg more than her nearest rival in the weights.

It's a challenge that became harder at acceptance time when Driefontein was given 2kg more than the stable expected.

"Originally we were told she was going to carry 59 kilos but then the field changed a bit and she has the 61," Newnham said.

But that's where Newnham expects Rawiller's reputation as one of Australia's best heavyweight riders to come to the fore as he partners Driefontein for the first time since the autumn carnival.

"With Nash you are not carrying much dead weight and you get the best," Newnham said.

"She's not the right horse to claim on and she needed the run prior to going to the Magic Millions as well."

Newnham said Waterhouse was weighing up two Magic Millions options for Driefontein during the Gold Coast racing and sales extravaganza next month - the $400,000 Cup and a 1300-metre race for fillies and mares.

"We'll let Gai decide which race she contests closer to the event," he said.

Driefontein hasn't been seen at the races since she finished fourth in a Group Three event for fillies and mares at Randwick on October 19 but she accounted for Shelford in a Randwick barrier trial at the start of the month.

She is getting ready for her third Magic Millions carnival appearance after winning the $2 million Classic on protest in 2012 and finishing third in this year's Guineas.

Since Waterhouse left for her annual European holiday, the stable's strike-rate has been holding up with King Cobia successful at Randwick last Saturday and Laidback Larry and Tamariz giving her a winning double at Canterbury on Wednesday.
