Kris Lees will be keeping a close eye on apprentice Samantha Clenton on Saturday and not just because he trains the horse which will be her only Rosehill ride.

Clenton will join the Newcastle trainer on a three-month loan, starting in two weeks.

The opportunity has come at the right time with Lees recently adding Melbourne Cup winner Protectionist to a stable that already boasts Group One winner Lucia Valentina.

"Hopefully it leads to bigger and better things," she said.

"It's going to open a lot of doors at the provincials and metropolitan area."

Clenton, who is based at Muswellbrook with master Tim McIintosh, has made a big impact despite limited city opportunities.

Rated one of the most promising junior talents in NSW racing, she will take confidence into the Rosehill meeting after riding her first city double at Canterbury on Wednesday, including a victory aboard the Bjorn Baker-trained One More.

Baker is a fan of Clenton and believes she has a bright future.

"She's only ridden a few horses for me but she's going to keep winning races, that's for sure," Baker said.

With three stakes races at Rosehill on Saturday, opportunities for apprentices are limited but Lees has entrusted Clenton with the ride on Terra Amata in the TAB Rewards Handicap.

The mare has won her past two starts, including a Canterbury victory two runs ago with Clenton in the saddle.

It has been a roller-coaster journey for the junior rider who grew up in the NSW mid-north coast town of Port Macquarie and was originally apprenticed to Mark Quinn.

Clenton said she wanted to be a jockey all her life but gave it away for two years for several reasons, including weight issues, before returning to the saddle 12 months ago.

She hasn't looked back.

"Mum reckons I could ride a horse before I could walk," she said.

Meanwhile, Melbourne jockey Dwayne Dunn has four Rosehill rides for Hawkes Racing, including Our Boy Malachi which will be trying to stay unbeaten for the stable in he Starlight Stakes.
