Chaos continues: Longshots won the final two Grade 1 Kentucky Derby prep races on Saturday, keeping the Run for the Roses wide open. In the Arkansas Derby, it was Archarcharch who scored the victory, making a strong move in midstretch and holding off the hard-charging Nehro. The son of Arch was sent off as a 25-1 shot despite his solid record at Oaklawn this winter; he won the Sugar Bowl and Southwest, then finished third in the Rebel. The latter race was won by The Factor, who was sent off as a heavy favorite in the Arkansas Derby, with a chance to cement his credentials moving on to Kentucky. But the colt appeared rank early when he didn't make the lead and faded badly down the lane to finish seventh. The Factor's loss, coupled with Uncle Mo's loss in the Wood Memorial last week, means that Florida Derby winner Dialed In will likely be a lukewarm Derby favorite - although Nehro, who was also a closing second in the Louisiana Derby, is likely to take some wide-guy action. Meanwhile in Kentucky, Brilliant Speed closed furiously from last to first to nail Twinspired on the wire in the Blue Grass Stakes. The son of Dynaformer, trained by Tom Albertrani, will be looking for his first victory on dirt in the Kentucky Derby. Favored Santiva was never in the mix and finished ninth, putting his Derby status in doubt, as he failed to move up the graded earnings list.

Feeling good: Risen Star winner Mucho Macho Man zipped seven furlongs in 1:23.66 at Gulfstream Park on Saturday morning. Going in a light rain, the colt ticked off fractions of :11.98, :34.98, :46.33, :58 and 1:10.66 despite going wide into the stretch. He galloped out in 1:38.70. The colt is scheduled to leave his Florida training base for Kentucky tomorrow.

Making plans: Trainer Kiaran McLaughlin detailed the schedule for Fountain of Youth winner Soldat on Saturday. The colt, who is based at Palm Meadows, will breeze on April 21 and April 29. He will ship to Churchill Downs on April 30 and gallop into the race. The colt is attempting to rebound from a fifth-place finish in the Florida Derby.
