Country Day finished second at long odds and Perfect Officer was up for third.
Regally Ready, a 4-year-old, Kentucky-bred More Than Ready gelding, finished the 5 furlongs on "good" turf in 56.48 seconds. The Churchill Downs turf course condition was upgraded to "firm" immediately after the race.
With Corey Nakatani up, Regally Ready was behind the early speed into the turn. When he found room on the inside, he sped through and opened up in the final sixteenth for the win.
Regally Ready started the year in California but recently has traveled North America for trainer Steve Asmussen. He won the Turf Sprint on Kentucky Derby Day at Churchill Downs, competed in New Jersey and Pennsylvania and then won the Grade I Neartic Stakes at Woodbine near Toronto in his last outing.
