With his ban from Churchill Downs-owned tracks behind him, horse racing's most famous trainer knows this week is "all about the horses."

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.
