当我在教选手们发球的时候,常常把发球比喻成棒球里的投手。在棒球运动中,有投掷的动作。大多投手可以把棒球投得非常快,但一个好的投手可以将速度、旋转和投掷方位完美的结合。这些方法同样可以在你的发球中得以运用。不要在每一次发球中玩命暴击,不要总是将球发向同一落点,首先你必须思考,之后才是发球。 When I teach tee-offs, I often compare servings to baseball pitchers. In baseball, there is a throwing action. Most pitchers can baseball very fast, but a good pitcher can be the perfect combination of speed, rotation and throwing. These same methods can be used in your serve. Do not crit crit in every service, do not always send the ball to the same place, first you have to think, then is the serve.
