The 148th edition of the Kentucky Derby is set to take place on Saturday as the iconic race looks to move on from last year's controversy.

Medina Spirit crossed the line first in 2021, but the horse later tested positive for a banned substance, meaning the result was nullified.

The horse's trainer, Bob Baffert, was subsequently banned for two years from Churchill Downs and initial runner-up Mandaloun was announced the race winner.

Baffert later provided a lengthy statement claiming an ointment used to treat dermatitis may have caused the positive test.

The episode, which took another sad twist after Medina Spirit unexpectedly died in December,

arguably continues to overshadow the spectacle which was first held back in 1875,

but the Derby is keen to leave the controversy in the past.

Without Baffert, who has won the race a record-equaling six times, the field is wide open for what promises to be an exciting contest.
