Kentucky Derby Field Set

ESPN:

Dialed In was listed as the 4-1 favorite by Daily Racing Form national handicapper Mike Watchmaker after being assigned post 8 in a full field of 20 3-year-olds entered to run Saturday in the 137th running of the $2 million Kentucky Derby at Churchill Downs.
Dialed In, with Julien Leparoux to ride, has won three of four career starts and will try to become the third Derby winner for trainer Nick Zito, who won in 1991 with Strike the Gold and in 1994 with Go for Gin. Dialed In won the Florida Derby in his last start.
Uncle Mo, the reigning divisional champion, was pegged as the close 5-1 second choice after being assigned post 18 for the 1 1/4-mile race. John Velazquez has the mount for trainer Todd Pletcher, who sent out the 2010 winner, Super Saver.
"I think he ought to be able to relax and track the main speed," Pletcher said before the draw. Asked whether Uncle Mo is healthy, he said: "He's doing well." Afterward, regarding post 18, Pletcher said, "I was okay with that."
Archarcharch (10-1) got the dreaded post 1.
"We're just going to make it work," said Jon Court, rider of Archarcharch.
Other choices on the morning line are Nehro (post 19, 6-1), Midnight Interlude (post 15, 12-1), Mucho Macho Man (post 13, 12-1), Shackleford (post 14, 20-1), and Soldat (post 17, 20-1).
Twice the Appeal (post 3), with Calvin Borel to ride, is listed at 30-1. Borel has ridden three of the last four winners of the Derby.
Watch Me Go (50-1) got post 20 on the far outside.

The entire lineup and morning line is posted at the link.  It looked like 30-1 was the field bet.  20 horses racing always makes things interesting.
