Final time was 1:43 4/5.Dyna Club went to the lead soon after the start and held it through fractions of :25 and :49 4/5 for the half-mile before picking it up in the stretch. Tropical Lady finished third behind Four Plus Four. Noches De Rosa, a first-time starter in the United States from Chile, closed strongly to finish fourth after encountering early trouble from her rail post. Irish-bred Reine De Romance, the 2-1 favorite, was no factor after a wide pulling trip.
