Saratoga was in focus for horse players last Saturday, featuring seven G1 races, including the $1.25 mil. Travers stakes for three-year-olds over 1 1/4 mi. on dirt. Unlike the previous Breeders Cup Qualifying race for three-year-olds in the Haskell, where the Handicap Wizard predicted the winner in Good Magic, the model ranked Gronkowski best this time. The horse did not win, and it is important to know why in order to understand the limitations of the model. Gronkowski had only one speed figure from its last race, which happened to be the highest in the field at 107. Consequently, there was no data to simulate with the horse; and unless the other horses had simulated speed figures that exceeded 107, a number that appeared dubious on its face because of the low E1 and LP figures that factored into it, Gronkowski would have had a 100% speed estimate, which is exactly what happened. This is a rare occurence and shows the pitfalls of applying the HW to a race with scant data, as there was with Gronkowski and Mendelsohn with three data points, who ended up placing 2nd. Even so, Catholic Boy’s win was not improbable, as the program rated his winning percentage fourth best at 10.26%, which was in-line with his post-time odds of 8-1. The other two top-three finishers, Mendelsohn and Bravazo, the HW rated in the top six according to WP.
