It seems like when I watch the pros return a big serve they are just blocking the serve for the return. Is this true? I just tried practicing my returns by blocking, standing closer in and taking a step forward when the server serves. I would block in a the direction that I thought would put the server in a defensive position so that they wouldn't be poised to hit a winner fo my return. If the serve is smaller (second serve) I stand a bit more back and take a small swing at it to make the return a little more difficult to handle. Am I taking the right approach? Is blocking okay for a return?
