Expected Stephen Foster Handicap (gr. I) favorite Mineshaft turned in a spectacular work Tuesday, breezing five furlongs in :59.60 over a fast Churchill Downs track. The move under exercise rider Annie Finney came just after the regular break for track maintenance and was the fastest of 31 at that distance."He went really, really well -- nice and easy," said trainer Neil Howard. "He usually does things in hand and today was no different. I didn't know he would go in 59-and-change, but he went good. Those kind of horses work like that. He did it well and the last quarter was phenomenal."Fractional times for the 4-year-old son of A. P. Indy were :12.40, :24.60, :36.80, and :48.20.
