William's tennis stroke analysis

William and Sim's stroke analysis. William: Pros William swung and finished up his stroke pretty good and accurate Cons Did not seem to always hit at sweet zone/find the ideal contact point(for right handed, it is about one racket length from your left foot toes, and at waist heights, we run to make this only ideal contact point if you do not run...your gesture will just incorrect ) It is about more practice for Williams..
