Nafzger told DRF that Street Sense would continue to be pointed for the Haskell (gr. I) or the Jim Dandy (gr. I), then the Travers (gr. I) and the Breeders' Cup.
Street Sense lost the Preakness Stakes (gr. I) on May 19 by a head to Curlin. He has won four of nine starts with earnings of $3.1 million.
