The trainer of Kentucky Derby winner Mystik Dan is sounding more optimistic about his horse possibly running in May 18th Preakness Stakes in Baltimore.  Trainer Kenny McPeek said on Monday the colt ate all of his dinner on Sunday night, which he called an encouraging sign.  Speaking to reporters Sunday morning, McPeek said he’s not committed to the Preakness because of concerns about running the horse twice in two weeks.  McPeek indicated a decision on the Preakness will probably be last-minute, but he says the horse is “doing fine and seems to be bright and happy.”  Meanwhile, Hall of Fame trainers Bob Baffert and D. Wayne Lukas plan to saddle two horses each in the middle jewel of horse racing’s Triple Crown
