Abstract: By using the Delphi method, and taking the mini baseball event for example, the author probed into the mode of “competition ranking + general standard score” for sport rating, built a standard index system for mini baseball competition general rating, which includes 35 Class A indexes, 22 Class B indexes and 8 Class C indexes. The research indicates that this “competition ranking + general standard score” evaluation system is easy to be popularized, highly operable and inclusive, widely applicable, and not restricted by age or gender, having great re-alistic significance and social value for increasing the national fitness population and competition organizers’ enthu-siasm, expanding event influence, and improving the public health level. This evaluation method can be referred to by the rating systems of other ball events.
