BALTIMORE (AP) -- The field for tomorrow's Preakness was reduced to 12 horses Friday morning when Behindatthebar was scratched with a bruised left front foot.

The Todd Pletcher-trained thoroughbred was listed at 10-to-1 for the 133rd Run for the Black-Eyed Susans.  Kentucky Derby winner Big Brown is an early 1-to-2 favorite to put himself in position to become horse racing's first Triple Crown winner since Affirmed in 1978.
