Is it because of the flick of the wrist necessary to generate the spiral? Same principal holds true in golf ... if you want to generate massive clubhead speed, it's all about waiting until the last moment to 'pull the trigger' and break your wrist to bring the clubhead through. Watching Serena's serve in slo-mo, the wrist snap is ridiculous.
