The last stop on the road is within sight. After 44 points-scoring races over 11 months, those desirous of running at Churchill Downs in the Kentucky Derby on Sept. 5, and their rankings on the points list, are set. As of Wednesday, there were just 21 horses still under consideration for the Derby, with at least two of those not certain to run in the race, leading to the very real possibility that fewer than the maximum of 20 will enter, let alone run.
