Trainer Les Ross is looking for a change of luck with River Racer when she runs in the Group Three Gold Coast Guineas.

River Racer ran her sixth second in a 12-race career when beaten a nose by Guineas rival Tiyatrolani at Doomben in the Listed Mick Dittman Plate two weeks ago.

It was also the fourth time she had picked up minor prize money in a stakes race including a second to Winning Rupert in the Vo Rogue Plate in December.

She lines up in Saturday's Guineas (1200m) with Robbie Fradd to resume his association with the filly after being sidelined with injury.

"Most people thought she had won at Doomben last time. It about sums up my luck of late. I have been having a long run of outs when everything is running second," Ross said.

Although River Racer has won only one race, she has $261,000 prize money to her credit and Ross hopes she can press on to the Queensland Guineas on June 10.

"She had no luck in the Magic Millions Guineas when sixth but only about three lengths away and River Racer has drawn badly on Saturday in barrier ten," Ross said.

"But your luck has to change and hopefully it will be on Saturday."
