The previously unbeaten Spectator, who won the Grade 2 Sorrento Stakes at 6 1-2 furlongs on Aug. 5, finished third as the 2-1 second choice, beaten 5 3-4 lengths. 

Dancing Belle finished fourth, followed by Just a Smidge, Poetic and Gabrieleelizabeth. Just a Smidge was the 9-5 favorite.

Moonshine Memories, who was ridden by Flavien Prat, was timed in 1:23.61. The Del Mar Debutante was the top race of the track's summer meeting, which ends on Monday.

Trained by Simon Callaghan, Moonshine Memories won her debut in a six-furlong race here on Aug. 19.
