Volume handled the step up to Listed level in style when making every yard of the running in the Swettenham Stud Fillies' Trial at Newbury.
Beaten in a handicap, which has worked out well, last time out, Luca Cumani's filly was given a clever ride by Richard Hughes.
He steadily increased the pace in the straight, as gradually his rivals dropped away one by one.
Irish raider Lahinch Classics looked to have her measure, though, with Wayne Lordan appearing confident at the furlong pole.
However, she could never quite get on terms and the 9-4 favourite held on by a neck.
Hadaatha was two lengths away in third with Inchilla fourth.
Sara Cumani, the trainer's wife, said: “The idea was to possibly make the running if nobody else wanted to and just ride her forgetting about what else was in the field. Richard Hughes said she jumped out nicely, found herself in front and he was happy to make the running on her.
"He asked her to go a nice easy pace as she has a high cruising speed and she's very genuine and she did it well.
"We're thrilled and it's very good for the owner.”
The race often serves as a trail for the Oaks, but Cumani sounded a warning note to ante-post punters, saying: “No plans as to where we'll go next although Richard did say he thought she wouldn't handle Epsom."
