Looks like the same three that won the Derby, maybe in the same order. The favorite, American Pharoah, runs from the dreaded #1 post position, but it's a much smaller field than usual, and stablemate, Dortmund, running from the #2 post shouldn't intentionally trap Pharoah on the rail.
Funny, they misspelled Pharoah.
