LOUISVILLE, Ky. (AP) — Twenty-two horses have been entered for Saturday’s Kentucky Derby, two more than the maximum field of 20.

The entry box closed Wednesday morning, with the surprise late entry of Tale of Verve. The draw to determine post positions is set for later in the afternoon. The field is limited to the top 20 horses based on points earned in designated prep races.

Leading the way is expected favorite American Pharoah, winner of the Arkansas Derby. The colt is trained by three-time Derby winner Bob Baffert, who will also saddle likely second favorite Dortmund, undefeated at 6-0.

Todd Pletcher will saddle four horses: Blue Grass winner Carpe Diem, Florida Derby winner Materiality, Itsaknockout and Louisiana Derby runner-up Stanford.
