Owned by the China Horse Club, the daughter of Exceed And Excel broke smartly from stall ten under Andrea Atzeni and she was soon up with the pace as the early tempo proved steady.
Angled between horses to challenge outside the two-furlong marker, Prosper knew job well enough to mow down long-time leader Music Lesson and get the better of a warm field of juvenile fillies by a comfortable half-length.
A half-sister to Doncaster Cup winner Pallasator from a stout staying family on the dam’s side, Prosper ought to improve with a winter on her back and middle-distances are likely to be in reach next season.
Roger said: “I thought Propser made a lovely introduction here. She showed an excellent attitude and the race looked useful on paper beforehand. I am delighted for the China Horse Club and she is something to look forward to for next year.”
