What has been the biggest change in tennis?
In my opinion, the biggest change in tennis has been the advent of technology. Modern gadgets like Hawk-Eye have revolutionized the way decisions are made, reducing human errors significantly. Moreover, the physical fitness and power of players have changed the game dramatically. From wooden rackets to graphite ones, the equipment evolution has also played a huge role. Lastly, the introduction of professional tennis in the open era, which allowed professionals to compete with amateurs, has made the sport more competitive and exciting.
