DEL MAR, Calif.- Hall of Fame jockey Mike Smith’s description of Lady of Shamrock’s rally best describes her style of victory in Saturday’s $300,000 Del Mar Oaks. “She goes from last to woom,” he said. “She’s got a great turn of foot. You’ve got to trust her.” Smith rode Lady of Shamrock ($4) confidently in the Grade 1 Del Mar Oaks and was rewarded when the filly closed with a remarkable rally to win by a half-length over 43-1 Stormy Lucy. Open Water, a 25-1 shot, finished third in the field of nine.
