“Dual-hand serving is a radical concept that will become more commonplace in tennis in the future.
The advantages in terms of preventing injuries in the shoulder are reason enough to teach both lefty and righty serving.
Dual-hand servers reduce the load on the shoulders, elbows and wrists by reducing the total serve count per shoulder per match.
In addition, the tactical advantages of having both a lefty and righty serve are manifold, including being able to slice wide to both boxes, and create a variety of spins on the ball.”
