The first Derby worker of the morning here at Churchill Downs was Bravazo, who went five furlongs that Daily Racing Form's early riser, Mike Welsch, caught in 1:01.71. Exercise rider Danielle Rosier was up.

After the work, trainer D. Wayne Lukas said Luis Contreras would have the mount. All 20 expected starters in the Derby now have confirmed riding assignments, with Noble Indy (Florent Geroux) and Instilled Regard (Drayden Van Dyke) also having been wrapped up in the past 72 hours.

Lukas conceded that coming into the Derby with Bravazo off a six-week break is not ideal.

“It’s a long time. You’ve got to do a little more work in the morning,” Lukas said. “He finished strong today, that’s the main thing. He puts a lot into his morning gallops. He’s got to improve. But he’s a tough horse. He’s a type you could take through the whole Triple Crown series.”

Lukas has won the Derby four times
