The pro coach shares the “Doorknob Drill” to help teach young players how to naturally hit topspin and focus on getting the ball up and down quickly.

“Because they’re so close to the net they’re going to be more apt to swing up and across,” Macci says about why this drill is so effective.

He explains how the wrist movement in his drill is very similar to that of turning a doorknob, making it easier for players to pick up the concept.
