Jesus Castanon has ridden in the United States for a little over 22 years. He is originally from Mexico, where he rode for three to four months before moving his tack to California. Castanon has ridden more than 2,000 winners; his win aboard Shackleford in the 2011 Preakness Stakes was his first Grade I stakes victory. Shackleford and Castanon did not duck a race for the entire 2011 campaign, with strong efforts in the Grade I Haskell Stakes (second) and the Grade I Breeders’ Cup Dirt Mile (second). However, it was a little over 50 weeks before they returned to the winner’s circle, in the Grade II Churchill Downs Stakes on Saturday.
