Lift is not the answer. In my opinion the answer is in your wrist. The bowlers that rev the ball have a greater angle change in their wrist during the thumb exiting the ball.

提拉并不是解决之道，我觉得问题在於手腕的运用，高转速的球员在姆指脱离球孔以后，手腕会作出相当程度的角度变化。

Most players who want to create greater revolutions on the ball usually overturn the ball with the thumb. But, it must be noted that unusually high revs are not dependent on raw power and speed. For example, Bob Vespi, now retired, generated great revolutions (six revs before rolling past arrows; taped by Don Johnson), yet Vepsi threw one of the slowest deliveries on the tour.

很多球员为了想得到较高的转速，姆指往往都转过了头，还有，快的转速并不纯然来自於手给予球的提拉力道及速度，举个例来说： Don Johnson 曾录下己退休球员 Bob Vespi 的掷球过程，他的球速在巡回赛的职业球员中算是超级慢的，但是他的球在还没到达箭头前却已经转了6圈。
