Bob Baffert is back at the Kentucky Derby for the first time in four years, having served his punishment for Medina Spirit’s failed drug test and coming to the place where he’s won a record-tying six times. He’s settled in at his old Barn 33, the signs boasting of his Churchill Downs triumphs again hanging on the outside wall.

Three years after Medina Spirit's victory was stripped due to a failed drug test, Baffert looks to reclaim his place at Churchill Downs.

No horse trainer has won the Kentucky Derby more times than Bob Baffert, who will be chasing a record seventh title at Churchill Downs this weekend when he returns following a suspension that kept him on the sidelines for the last three years.
