Curlin’s incredible streak of classic success is likely to come to an end this season. The stallion, who produced a classic winner or classic-placed runner from each of his first six crops, didn’t have a starter in this year’s Kentucky Derby or Preakness, and does not have any progeny currently under consideration for the Belmont Stakes. However, the Hill ‘n’ Dale Farm stallion is streaking through an outstanding spring, and is set to be represented on the star-studded Belmont Stakes undercard.
