Ricardo Santana Jr., the leading rider at Oaklawn, and Luis Quinonez, the 2007 title winner in Hot Springs who also won five championships at Canterbury, will be based at Churchill Downs for the first time in their careers following the end of the Oaklawn meet April 13.
Santana, 19, had won 52 races at Oaklawn through Wednesday. Last year, he took the title at Delaware Park. The next stop will be the Churchill meet that opens April 27, said his agent, Ruben Munoz.
