Spinning of ball as explained by Bernoulli's theorem

As it is the cricket world cup season, the scientific explanation of spinning of balls is as follows --------- When a spin bowler is spinning the ball by his fingers, due to spinning of air layers around the ball, there will be more velocity at upper side of ball than at the lower side . According to Bernoulli's theorem, this results in more pressure at the lower side of ball than the upper side . This difference of pressure gives rise to dynamic lift on ball , giving rise to bounce and also the drag of ball. Thus a spinner is able to spin the ball .
