And they're off .... bettors are already suing Bob Baffert over the Kentucky Derby, claiming he knowingly cheated and screwed gamblers out of serious cash.
Baffert has been hit with a class action lawsuit by several gamblers who claim they had money on the Kentucky Derby ... and feel Baffert cheated them out of their winnings by running a "drugged horse."
As we previously reported, Baffert -- the most famous trainer in the history of the sport -- trained Medina Spirit, which won the 2021 Kentucky Derby.
After the race, Medina Spirit tested positive for the banned substance betamethasone, an anti-inflammatory steroid.
