Triple Crown champion American Pharoah is the early 6-5 favorite in a field of 10 for the $5 million Breeders' Cup Classic, the last race of his career.
The colt will break from the No. 4 post on Saturday at Keeneland. He is coming off a loss in the Travers two months ago.
Beholder drew the far outside post and is the 3-1 second choice for the 1 1/4-mile race against male horses.
Tonalist, the 2014 Belmont Stakes winner, and Honor Code are the co-third choices at 6-1. Tonalist, who ended California Chrome's Triple Crown bid last year, drew the No. 1 post, while Honor Code is in the No. 9 position.
