Wilson has updated the Pro Staff for 2023 with their version 14 edition, introducing the latest iteration of this legendary tennis racquet series. This new racquet, called the Pro Staff X, boasts a larger head size of 100 square inches. The Pro Staff X features Wilson's new paradigm bending carbon-fiber construction that optimizes the flex between the hoop and the shaft, resulting in even more precision and feel, which are the hallmarks of the Pro Staff franchise.
