Though I respect Forever Unbridled, who is easily the most accomplished filly in the upcoming Fleur De Lis at Churchill Downs, I'm inclined to take a shot against her given she is unraced since running third in the Breeders' Cup Distaff last fall.
Big World (5) is my alternative play - a horse that figures to start at around 6-1 based on Pick 3 will-pays heading into this race.
Though Big World enjoyed a favorable trip in winning the La Troienne earlier at this meet on the lead, and against a field that seemed soft by Grade 1 standards, it is important to realize that she made her own luck in terms of trip. A filly with tactical speed, she often finds herself in a sweet spot, either close to a slow pace or stalking when fractions are quick.
