Bob Baffert is back at Churchill Downs.
It's the biggest storyline Saturday ahead of the 151st running of the Kentucky Derby in Louisville, Kentucky, as the embattled trainer makes his return for the first time in three years.
A win on Saturday with Citizen Bull would give him 17 wins at Triple Crown race tracks. It would also put him in a class by himself with seven Kentucky Derby victories, which would be the most all-time by a trainer. Baffert originally had two horses running in the derby, but Rodriguez was scratched from the field on Thursday.
