(1) There is an edX course entitled Math in Sports, with the following prereqs:
Participants will be expected to have a basic knowledge of high school math up to Algebra II, exposure to some probability, statistics, and geometry will be helpful, but is not required.
It could be worthwhile to enroll in this course.
Taught by a professor of Math and a professor of Physics, Notre Dame.

Minton, Roland B. Sports Math: An Introductory Course in the Mathematics of Sports Science and Sports Analytics. CRC Press, 2016.
Here from Mathematical Reviews, 2017:
The book is written at a level that is accessible to a large audience. It contains a small number of applications that make use of calculus; otherwise, only a high school level mathematics background is required. Furthermore, one can easily skip over those sections that require calculus and still have plenty of accessible material to read.
Sports Math is well written and easy to read. The book should appeal to anyone interested in the quantitative aspects of athletics. Each chapter of the books ends with a fairly large number of exercises and also pointers to further reading. Thus, the book could be used not only as a textbook for a course but also as a nice resource for student projects.

Caveat: I have not used either of these resources.
