The Jim Bolger-trained filly had run consistently well in defeat since her last success at the Curragh in September 2017 and enjoyed herself after herself on the rain-softened ground.
Wearing the Godolphin colours, the daughter of Pivotal led before the home turn, but was strongly pressed by Ship Of Dreams in the closing stages.
However, Panstarr (8-1) kept on gamely for Kevin Manning to get the verdict by a neck. The leading pair were four and a half lengths ahead of Hence in third.
“She is a very versatile four-year-old filly and is now a Group Three and Listed winner,” said Bolger’s travelling head man, Ger Flynn.
“She likes the soft ground and goes on good and is one hopefully we may keep in training next year.”
He added: “It was good to get the win with her and Kevin was fantastic on her.
“The draw was key and he was very positive and strong from the get-go, an unbelievable drive to the line to get her to win.”
