Trainer announced Sunday morning Kentucky Derby winner Medina Spirit tested positive for betamethasone.

Trainer Bob Baffert told reporters the horse has never been treated with that drug and has promised an investigation.

Most horses from the Kentucky Derby are not expected to race in the Preakness on May 15, but Kentucky Derby winner Medina Spirit could make a run.

Jim McIngvale – also known as “Mattress Mack” – is driving down the odds on Essential Quality as insurance to cover promotion at his stores.

King Fury, a $950,000 purchase who won the Grade 3 Lexington on April 10 at Keeneland, will be added to the Kentucky Derby field.
