Melbourne mare Secret Agenda will be on the road again after claiming a Group Two win at Randwick.

The Mick Price-trained four-year-old was a dominant winner of Saturday's Sapphire Stakes (1200m) to confirm a trip to Adelaide for a tilt at the Group One sprint double of the Goodwood and the Robert Sangster Stakes.

"She's a good mare and she's a good wet tracker which is why we brought her here," Price said.

"She is on the way up this preparation and we will take her to Adelaide for the Group Ones, the Goodwood which is worth a million dollars and the Sangster.

"We won one of those races a few years back with Velocitea."

Price trained Velocitea to run second in the 2010 Sangster before she won the Goodwood."

Ridden by Damien Oliver, Secret Agenda ($9.50) raced just behind the leaders and unleashed a powerful finishing sprint to beat Missrock ($21) by 1-1/4 lengths.
