5. It's all about the points: For the first time in Derby history, the field of 20 starters is being determined by points. Churchill Downs instituted a tiered system that awards a sliding scale of points to the top four finishers in 36 designated races. The top 20 point earners at the end of the series will earn a spot in the Derby starting gate if more than 20 horses enter. If two or more horses have the same number of points, earnings in non-restricted stakes races will be the tiebreaker. From 1986-2012, earnings in graded stakes were used to decide which 20 horses ran in the Derby.
