Vasilika rallied wide in the final quarter-mile to win her third consecutive start and give leading rider Flavien Prat his third winner of the afternoon.
Prat's next mount is Aunt Lubie (3) in the sixth race, for maiden fillies and mares.
Vasilika ($4.20) won Friday's race, an allowance race at 1 1-8 miles on turf, by 3 1-4 lengths over The Tulip, a 3-1 chance. Vasilika was timed in 1:46.67.
Trained by Jerry Hollendorfer for a partnership, Vasilika was claimed for $40,000 in February. She was second in an optional claimer on March 4 and has won her last three - the March Madness starter handicap and two optional claimers.
A 4-year-old by the Skip Away stallion Skipshot, Vasilika has earned $107,088 since being claimed.
