"LaPenta bought (apparently, the listed buyer was Whitehorse Stables) Cool Coal Man for $200,000 as a yearling at Keeneland and then bought him back for $850,000 at the Fasig Tipton 2yo sale last year. He was entered in the Keeneland 2yo sale in April but withdrawn."

Obviously the Mineshafts don't move well and are possibly sore.
