When Be Your Best finished a well-beaten third Saturday at Saratoga after running out to a big lead in the Flower Bowl Stakes, her trainer, Saffie Joseph Jr., praised the way the mare was ridden. For her best chance, Be Your Best needed to press her advantage as the race’s lone speed horse. Well, here we go again. The Joseph-trained No Mo Candy can control the pace Thursday at Kentucky Downs in the $500,000 One Dreamer Stakes. And it might behoove jockey Irad Ortiz Jr. to let the filly rock and roll.
