Hours before the 139th running of the Kentucky Derby at Churchill Downs, $9.1 million of bets have already been placed, according to the track’s official site.

A scratch by the initial favorite, Black Oynx, has opened up the legendary race for a number of horses, and new favorites have emerged.

Based on overnight betting, Revolutionary comes in at 5-to-1 and Goldencents at 6-to-1, supplanting Orb and Verrazano, though both are still among the top four favored.

Giant Finish and Falling Sky are the biggest long shots, at 40-to-1 and 39-to-1, respectively.

The lines will continue to move throughout the day, and updates will be posted leading up to the race.

Coverage of the race begins at 4 p.m. and the Derby is scheduled for 6:24 p.m. EDT. It will be broadcast by NBC, or you can watch the live online stream at NBC Live Extra here.
