LOUISVILLE, Ky.—Bob Baffert endured the lowest of lows and highest of highs within minutes in the Kentucky Derby.
He was bummed before the horses left the paddock after Thousand Words reared up and fell on its side, getting disqualified and injuring Baffert’s assistant trainer. That emotion was quickly replaced by Authentic’s front-running victory that gave Baffert a record-tying sixth Derby win.
