BC Stables’ Virginia Derby winner American Promise wasted no time going to the track Saturday morning, working five furlongs in :59.40 with jockey Nik Juarez up.

American Promise worked by himself at 5:30 on a track rated sloppy.

Churchill Downs clockers timed American Promise in fractions of :12, :23.80, :35.40, :47, :59.40 and out six furlongs in 1:12.40 for trainer D. Wayne Lukas.

Juarez arrived in Louisville at 8:30 Friday night after driving to Kentucky from Oaklawn Park.

“Got here last night, ready to work this morning,” Juarez said. “He was ready to work too and the off track was not a problem.”

Juarez rode American Promise for the first time in the Virginia Derby when the Justify colt won by 7 ¾ lengths. American Promise broke his maiden over a muddy track at Oaklawn Park on Dec. 29. Juarez, a Maryland native, will ride in his first Kentucky Derby.

American Promise is a half-brother to Grade II stakes winner Hoosier Philly who will be shooting for millionaire status Saturday afternoon at Oaklawn Park in the $200,000 Dig A Diamond Stakes. She has earned $974,465.

American Promise was among five Kentucky Derby hopefuls with timed workouts Saturday morning at Churchill Downs under three track conditions. Others were Burnham Square, Render Judgment, Final Gambit, and Tappan Street.

However, one of the five, WinStar Farm, CHC Inc. and Cold Press Racing’s Tappan Street will not be participating in Kentucky Derby 151. The Brad Cox trainee exited his five-furlong work in :59.60 with a right foreleg injury.

That opens the door to Render Judgment, who, after some waffling on the part of his connections, now appears to be pointed to the Derby field. Julien Leparoux has been named to ride for trainer Kenny McPeek.

Santa Anita Derby runner-up Baeza now needs one scratch to draw into the Kentucky Derby.
