Grade I winners Urbane and Prenup head the list of 140 horses entered to run on the Oct. 14 Maryland Million card at Laurel Park.
The actual starting fields and post position draw will be held Thursday.
Urbane ships in Tuesday from California and is scheduled to race in the Maryland Million Oaks at 1 1/8 miles on the dirt. Owner Samantha Siegel said she is trying to line up Corey Nakatani to ride the 3-year-old daughter of Citidancer.
Prenup, headquartered at Belmont Park, will try for a repeat victory in the Sprint.
