The field is set for the 146th Preakness Stakes at Pimlico Race Course in Baltimore, Maryland. Kentucky Derby winner Medina Spirit is the nine-to-five morning line favorite in Saturday’s race.  He’ll break from the number three post position in the ten-horse field.  An agreement was reached to allow the Bob Baffert-trained colt to compete despite a failed drug test after his Derby win.  The horse must undergo pre-race drug testing and he’ll be scratched if any banned substances are detected.  Another Baffert horse, Concert Tour, will break from the number ten post.
