Spoke to Javier Castellano a little while ago who told me that he will ride Audible, the Florida Derby winner, in the Kentucky Derby. Castellano had ridden Bolt d'Oro to a second-place finish in the Santa Anita Derby and to a win, via disqualification, in the San Felipe.

Castellano told me that he chose to ride Audible more so out of loyalty to trainer Todd Pletcher and the connections that include WinStar Farm.

"I feel like I need to be with Todd," Castellano said.

Castellano rode Audible in the Holy Bull but was in Dubai when Velazquez rode him in the Florida Derby. Velazquez will ride Vino Rosso, on whom he won Saturday's Wood Memorial. Pletcher still needs a rider for Noble Indy, the Louisiana Derby winner.

Meanwhile, Mick Ruis, the owner and trainer of Bolt d'Oro needs to confirm a rider for his horse. It has been speculated that Victor Espinoza is the leading candidate to get that mount.
