European invader Heart Shaped finished second and Laragh, the favorite, finished third after setting a brisk pace most of the way. The 1 mile race over the firm turf took 1:35.15.
With Jose Lezcano in the irons for trainer Chad Brown, Maram rolled down the center of the track to take the lead in deep stretch, then held off the late, outside run of Heart Shaped. Maram is a Kentucky-bred filly by Sahm.
It was only the third start for the dark bay or brown filly. She won her first start in a claiming race over the grass at Saratoga, then followed that with a neck victory in the Grade III Ms Grillo at Belmont park in New York over yielding turf.
Laragh also won her last start, the Jessamine at Keeneland. Before that, she raced at Woodbine in Canada. Heart Shaped had only a single win in five tries in Ireland and England before shipping to California for the Breeders' Cup.
