Kentucky Derby Clocker Report - Monday, May 1

Trainer Dan Hendricks waited until 8:30 a.m. before finally deciding to work Brother Derek on Monday, and another hour for the arrival of jockey Alex Solis.

Brother Derek, the likely favorite for Saturday's Kentucky Derby, breezed a half-mile in 49.36 seconds over a muddy track at Churchill Downs. Brother Derek was one of three Derby hopefuls to work on Monday morning, along with Storm Treasure and Private Vow.

Hendricks postponed a decision on whether to work Brother Derek until right after the renovation break because of the condition of the racetrack, which took a lot of rain on Sunday. Solis arrived late after taking the red eye from California and making the two-hour drive to the track from Cincinnati.

Earlier in the morning, trainer Steve Asmussen sent out Storm Treasure and Private Vow to work over a track that had a bit more moisture in it than when Brother Derek breezed three hours later.

Storm Treasure, working in the dark shortly after the track opened at 6 a.m., went five furlongs in 1:00.20. He was followed about 30 minutes later by Private Vow, who covered the same distance in :59.82. Both horses had Asmussen's exercise rider Carmen Rojas aboard.
