Drayden Van Dyke won for the second time in as many mounts on Wednesday aboard Candura ($4.60) in the fourth race for 2-year-old maiden fillies.
Candura closed from fourth in a field of eight to win by three-quarters of a length over 7-1 Mo Me Mo My who looked like a winner - albeit briefly - in the final sixteenth.
Van Dyke won seven races on Sunday, equaling Victor Espinoza's 2006 record.
Candura, a filly by Into Mischief, races for Pete and Kosta Hronis and was purchased for $240,000 at the Fasig-Tipton October Yearling Sale in 2017.
Van Dyke's next mount is Don't Stalk Me (7) in the eighth race.
