Trainer Steve Asmussen’s Derby 134 duo of Pyro and Z Fortune had just completed their final workout before Saturday’s Kentucky Derby. Both 3-year-old colts looked sharp during their half-mile breezes. Pyro, the more playful of the two, covered the distance in 49.80 seconds; Z Fortune, the laid-back one, went in 51.00.

Shaun Bridgmohan will be back aboard Pyro, while Curlin’s regular rider, Robby Albarado, has the call on Z Fortune.
