The importance of assessing the jockey is critical when selecting a horse on which to bet. On average, only about 20 percent of all jockeys win about 80 percent of all races. A big reason for such consistent success is due to the jockey’s special riding abilities, but an equally big part is the fact that the owners of the best race horses also want the best jockeys to ride them. Once a jockey has established that he or she is among the best, owners of top horses will seek the jockey’s assistance in winning as many races and as much money as possible. The more races won and the larger the purses, the more likely a horse will remain a strong earner well into its retirement years through stud and breeding fees, and that requires putting the best jockeys on the best horses. So knowing which jockeys are the best in a given field can help improve handicapping results.
