Drayden Van Dyke's seven-win day on Sunday has moved him into the lead in the jockey's standings with 26 wins one more than longtime leader Flavien Prat.
The competition may not be decided until the closing day of the summer meeting, on Sept. 3. Beginning with Wednesday's card, there are 11 racing days remaining.
Prat will have limited opportunities on Saturday. He is serving the final day of a three-day suspension from earlier this month, and has one mount - Ransom the Moon in the Grade 2 Pat O'Brien Stakes.
This afternoon, Prat has one mount - Siberian Iris (1) in the first. Van Dyke has three rides on the eight-race program, the first of which is Gunmetal Gray (2) in the second.
