The early favorite for the 145th Kentucky Derby this weekend will not race after a breathing issue was detected Wednesday. Omaha Beach will need surgery to fix the issue and will be forced to the sidelines for this Saturday’s opening race of the Triple Crown. The revised odds give five-time Derby winner Bob Baffert the top three choices in the 20-horse field. Game Winner is the new favorite at 9-2. Improbable and Roadster are next at 5-1. Baffert can tie trainer Ben Jones for the most Derby wins if one of the three tops the field.
