Pressureless is a Privilege
Each Wednesday this site examines, dissects, and generally overthinks the rules of tennis. Currently we are examining the specifications for the different types of balls that are approved by the ITF for sanctioned competition. Last week I stumbled across an article on the USTA Colorado website that provided a tidbit of information that had eluded me in previous analysis. Pressureless tennis balls are recommended for play at high altitude. In fact, pressureless balls have previously been used by ATP tournaments played in Mexico City. I was astonished to learn that fact.
