 The Kentucky Derby began using a starting gate in 1930 and is limited to 20 post positions. Based on 43 starts, not one single horse has won from post-17. The last horse to finish second or third from post-17 was 35 years ago. And even worse, the average finish from this post is 11th. I think I know which post position I'm not going to bet. By contrast, the top three best positions based off 20 or more starts are post-5 with a win percentage of 10.8%, post-10 at 10.5%, post-15 at 9.8%. In the Kentucky Derby, where you start may determine where you finish. Bet the Kentucky Derby Saturday, May 6 with Fandall Sportsbook.
