Holy Bull was the favorite in the 1994 Kentucky Derby but after breaking poorly, he finished a distant 12th on a sloppy track. Croll later claimed that the horse must have been tampered with, as he had behaved in an uncharacteristically lethargic manner before the race. The purpose of the tampering, in this claim, was to knock out the odds-on favourite to create a dutch book. Holy Bull was treated for several days after the race with antibiotics against a possible infection and missed a few days of training.
